164-606: The Mazda Luce ( Japanese : マツダ・ルーチェ , Hepburn : Matsuda Rūche ) is an executive car that was produced by Mazda in Japan from 1966 until 1991. It was widely exported as the Mazda 929 from 1973 to 1991 as Mazda's largest sedan. Later generations were installed with luxury items and interiors as the Luce became the flagship offering. The Luce was replaced by the Sentia in 1991 which

328-511: A hardtop coupé and sedan , with a station wagon launched in 1973 to replace the Savanna Wagon . Under the hood at first was a 130 or 120 PS (96 or 88 kW) 12A engine, with the higher-powered version reserved for the five-speed GR-II and GS-II models. The extra power was due to a different exhaust and adjusted ignition timing. The emissions scrubbed "AP" models had five horsepower less, although after June 1973 they received

492-507: A 0 to 60 mph (0 to 97 km/h) time of 17.5 seconds and a 20.5 seconds and 105 km/h (65 mph) quarter-mile. Unlike the rotary cars, the 1800 was a flop. Road & Track magazine said it was solid to the point of being overly heavy, with pleasant handling but poor performance. It was gone from the market for 1972. Opposite to what happened in the US, in Europe the 1800

656-439: A 1974 comparison test of six wagons, with an 11.7 s sprint to 97 km/h (60 mph) and an 18 s/77.5 mph quarter-mile. The magazine noted that the wagon's brakes suffered from the extra 136 kg (300 lb) weight compared to the coupé. The RX-4 was on Road & Track magazine's Ten Best list for "Best Sports Sedan, $ 3500–6500" in 1975. The first Mazda 929 was introduced in 1973, as an export name for

820-545: A 2.2-liter four-cylinder, and a 3.0-liter V6. The V6 model was called the President trim level. In May 1997 the Potentia was given a thorough facelift, with a more bulkier, more aggressive front design and heavier looking taillights. Sold as the "New Potentia," this facelift was developed by Kia themselves and was not used by Mazda. The upper versions of the Potentia were replaced by the more expensive Kia Enterprise , which

984-482: A RWD configuration. This generation vehicle was sold in North America in sedan bodystyle only beginning with the 1988 model year; the hardtop was not available, nor were the rotary engines. Actor James Garner was used as a spokesman introducing the 929 to North America. The HC platform came out in two variations during its five-year span that had identical engines and interior but with two distinct body shapes;

1148-576: A Wankel engine are thus mainly limited by tooth load on the synchronizing gears. Hardened steel gears are used for extended operation above 7,000 or 8,000   rpm. In practice, automotive Wankel engines are not operated at much higher output shaft speeds than reciprocating piston engines of similar output power. Wankel engines in auto racing are operated at speeds up to 10,000   rpm, but so are four-stroke reciprocating piston engines with relatively small displacement per cylinder. In aircraft, they are used conservatively, up to 6500 or 7500   rpm. In

1312-405: A Wankel rotary engine, the chamber volume V k {\displaystyle V_{k}} is equivalent to the product of the rotor surface A k {\displaystyle A_{k}} and the rotor path s {\displaystyle s} . The rotor surface A k {\displaystyle A_{k}} is given by the rotor tips' path across

1476-400: A Wankel rotary engine, the eccentric shaft must make three full rotations (1080°) per combustion chamber to complete all four phases of a four-stroke engine. Since a Wankel rotary engine has three combustion chambers, all four phases of a four-stroke engine are completed within one full rotation of the eccentric shaft (360°), and one power pulse is produced at each revolution of the shaft. This

1640-637: A benefit from the in-group to the out-group) means "[I/we] explained [it] to [him/her/them]". Such beneficiary auxiliary verbs thus serve a function comparable to that of pronouns and prepositions in Indo-European languages to indicate the actor and the recipient of an action. Japanese "pronouns" also function differently from most modern Indo-European pronouns (and more like nouns) in that they can take modifiers as any other noun may. For instance, one does not say in English: The amazed he ran down

1804-399: A boundary layer from overheating working parts. The University of Florida proposed the use of heat pipes in an air-cooled Wankel to overcome this uneven heating of the block housing. Pre-heating of certain housing sections with exhaust gas improved performance and fuel economy, also reducing wear and emissions. The boundary layer shields and the oil film act as thermal insulation, leading to

1968-594: A complex system of honorifics , with verb forms and vocabulary to indicate the relative status of the speaker, the listener, and persons mentioned. The Japanese writing system combines Chinese characters , known as kanji ( 漢字 , ' Han characters') , with two unique syllabaries (or moraic scripts) derived by the Japanese from the more complex Chinese characters: hiragana ( ひらがな or 平仮名 , 'simple characters') and katakana ( カタカナ or 片仮名 , 'partial characters'). Latin script ( rōmaji ローマ字 )

2132-539: A coupé, also exported as the 929 coupé. The Luce and Cosmo both offered rotary, gasoline-powered piston-engines, and also a 2.2-liter diesel engine. An LPG -powered 2.0-liter version of the Luce sedan was also built for the Japanese market until December 1995 for taxi and other fleet usage. This generation Mazda Luce was known as the Haima HMC6470L in China and was produced from 1992 to 2002. A 2.0 or 2.2 liter engine

2296-414: A distinct language of its own that has absorbed various aspects from neighboring languages. Japanese has five vowels, and vowel length is phonemic, with each having both a short and a long version. Elongated vowels are usually denoted with a line over the vowel (a macron ) in rōmaji , a repeated vowel character in hiragana , or a chōonpu succeeding the vowel in katakana . /u/ ( listen )

2460-521: A facelifted version of the previous generation). The turbo version was never offered in Europe, and neither was the four-door hardtop, although parts of Europe bordering on Eastern Europe and the Middle East did receive it. Engines: The 1986 Luce was large and luxurious on the HC platform , now with the 13B turbo engine as one of many engine options. It was still exported as the 929, and differed from

2624-406: A fresh air supply to the exhaust port. It also proved that a Reed-valve in the intake port or ducts improved the low rpm and partial load performance of Wankel engines, by preventing blow-back of exhaust gas into the intake port and ducts, and reducing the misfire-inducing high EGR, at the cost of a slight loss of power at top rpm. Elasticity is improved with a greater rotor eccentricity, analogous to

2788-416: A fuel injected 120 PS (88 kW) version of the 2-liter engine was also introduced for the Japanese market; it was only available with the hardtop bodywork and full equipment. The 929 was replaced after November 1981 by the next generation Luce/929, although the second generation station wagon continued in production until March 1988 as no wagon replacement of subsequent generations was ever developed. At

2952-419: A glide /j/ and either the first part of a geminate consonant ( っ / ッ , represented as Q) or a moraic nasal in the coda ( ん / ン , represented as N). The nasal is sensitive to its phonetic environment and assimilates to the following phoneme, with pronunciations including [ɴ, m, n, ɲ, ŋ, ɰ̃] . Onset-glide clusters only occur at the start of syllables but clusters across syllables are allowed as long as

3116-439: A glow-plug for the leading site spark plug improved low rpm, part load, specific fuel consumption by 7%, and emissions and idle. A later alternative solution to spark plug boss cooling was provided with a variable coolant velocity scheme for water-cooled rotaries, which has had widespread use, being patented by Curtiss-Wright, with the last-listed for better air-cooled engine spark plug boss cooling. These approaches did not require

3280-431: A high incidence of sealing loss, both between the rotor and the housing and also between the various pieces making up the housing. Also, in earlier model Wankel engines, carbon particles could become trapped between the seal and the casing, jamming the engine and requiring a partial rebuild. It was common for very early Mazda engines to require rebuilding after 50,000 miles (80,000 km). Further sealing problems arose from

3444-441: A high-conductivity copper insert, but did not preclude its use. Ford tested a Wankel engine with the plugs placed in the side plates, instead of the usual placement in the housing working surface ( CA 1036073   , 1978). Wankel engines are capable of high-speed operation, meaning they do not necessarily need to produce high torque to produce high power. The positioning of the intake port and intake port closing greatly affect

3608-629: A higher roofline but retained the BMW-esque look. It was a front-engine, rear-wheel-drive four-door sedan , and featured a square 1490 cc 1500 SOHC engine, producing 78 PS (57 kW) at 5500 rpm and 114.6 N⋅m (84.5 lb⋅ft). It sold poorly at ¥ 695,000. The 1500 SS version with twin carburettors was introduced in June 1967, producing 86 PS (63 kW) at 5500 rpm and 117.8 N⋅m (86.9 lb⋅ft) at 5500 rpm. A stroked 1.8-liter (1796 cc) 1800 engine

3772-484: A listener depending on the listener's relative social position and the degree of familiarity between the speaker and the listener. When used in different social relationships, the same word may have positive (intimate or respectful) or negative (distant or disrespectful) connotations. Japanese often use titles of the person referred to where pronouns would be used in English. For example, when speaking to one's teacher, it

3936-423: A longer stroke in a reciprocating engine. Wankel engines operate better with a low-pressure exhaust system. Higher exhaust back pressure reduces mean effective pressure, more severely in peripheral intake port engines. The Mazda RX-8 Renesis engine improved performance by doubling the exhaust port area relative to earlier designs, and there have been studies of the effect of intake and exhaust piping configuration on

4100-412: A low temperature of the lubricating film (approximate maximum 200 °C or 390 °F on a water-cooled Wankel engine). This gives a more constant surface temperature. The temperature around the spark plug is about the same as in the combustion chamber of a reciprocating engine. With circumferential or axial flow cooling, the temperature difference remains tolerable. Problems arose during research in

4264-406: A more steady idle, because it helps to prevent blow-back of burned gases into the intake ducts, which cause "misfirings" caused by alternating cycles where the mixture ignites and fails to ignite. Peripheral porting (PP) gives the best mean effective pressure throughout the rpm range, but PP was also linked to worse idle stability and part-load performance. Early work by Toyota led to the addition of

4428-528: A pillared four-door sedan as well as a slightly larger pillarless four-door hardtop. While the pillared model was common in all countries that allowed the importation of the 929 (including the US and Canada), the pillarless model was predominantly seen in the Asian and Australian markets. The Canadian 929 came with a "Winter Package" option and included heated seats, a higher grade alternator, winter tires and non-recessed windshield wipers. A five-speed manual gearbox

4592-531: A result of the poor efficiency, a Wankel engine with peripheral exhaust porting has a larger amount of unburnt hydrocarbons (HC) released into the exhaust. The exhaust is, however, relatively low in nitrogen oxide (NOx) emissions, because the combustion is slow, and temperatures are lower than in other engines, and also because of the Wankel engine's good exhaust gas recirculation (EGR) behavior. Carbon monoxide (CO) emissions of Wankel and Otto engines are about

4756-410: A rotary type of engine in 1934. He realized that the triangular rotor of the rotary compressor could have intake and exhaust ports added producing an internal combustion engine. Eventually, in 1951, Wankel began working at German firm NSU Motorenwerke to design a rotary compressor as a supercharger for NSU's motorcycle engines. Wankel conceived the design of a triangular rotor in the compressor. With

4920-450: A second prototype of the DKM was built. It had a working chamber volume V k of 125 cm and also produced 21 kW (29 PS) at 17,000   rpm. It could even reach speeds of up to 25,000   rpm. However, these engine speeds distorted the outer rotor's shape, thus proving impractical. According to Mazda Motors engineers and historians, four units of the DKM engine were built;

5084-408: A sentence need not be stated and pronouns may be omitted if they can be inferred from context. In the example above, hana ga nagai would mean "[their] noses are long", while nagai by itself would mean "[they] are long." A single verb can be a complete sentence: Yatta! ( やった! ) "[I / we / they / etc] did [it]!". In addition, since adjectives can form the predicate in a Japanese sentence (below),

5248-428: A single adjective can be a complete sentence: Urayamashii! ( 羨ましい! ) "[I'm] jealous [about it]!". While the language has some words that are typically translated as pronouns, these are not used as frequently as pronouns in some Indo-European languages, and function differently. In some cases, Japanese relies on special verb forms and auxiliary verbs to indicate the direction of benefit of an action: "down" to indicate

5412-511: A single-barrel carb replaced the existing engines. First presented in Japan in October 1979 was a facelifted LA4 version with large, rectangular headlights and a more orthodox and European front appearance. The final addition was a 2.2-liter diesel engine produced between August 1980 and July 1981 for the sedan (LA4SS) from November 1981 for the wagon (LA4SV). Its output was 66 PS (49 kW) and 141 N⋅m (104 lb⋅ft). In October 1980,

5576-498: A single-rotor Wankel engine produces the same average power as a V h {\displaystyle V_{h}} single-cylinder two-stroke engine , with the same average torque, with the shaft running at the same speed, operating the Otto cycles at triple the frequency. Richard Franz Ansdale, Wolf-Dieter Bensinger and Felix Wankel based their analogy on the number of cumulative expansion strokes per shaft revolution. In

5740-403: A stationary center shaft, the DKM engine was impractical. Wolf-Dieter Bensinger explicitly mentions that proper engine cooling cannot be achieved in a DKM engine, and argues that this is the reason why the DKM design had to be abandoned. NSU development chief engineer Walter Froede solved this problem by using Hanns-Dieter Paschke's design and converting the DKM into what would later be known as

5904-456: A thermal reactor or catalyst converter may be used to reduce hydrocarbon and carbon monoxide from the exhaust. Mazda uses a dual ignition system with two spark plugs per chamber. This increases the power output and at the same time reduces HC emissions. At the same time, HC emissions can be lowered by reducing the pre-ignition of the T leading plug relative to the L trailing plug. This leads to internal afterburning and reduces HC emissions. On

6068-425: A thin dimensional galvanized chrome layer. This allowed Mazda to return to the 3mm and later even 2mm thick metal apex seals. Another early problem was the build-up of cracks in the stator surface near the plug hole, which was eliminated by installing the spark plugs in a separate metal insert/ copper sleeve in the housing instead of a plug being screwed directly into the block housing. Toyota found that substituting

6232-561: A trial basis 40-octane gasoline was produced by BV Aral, which was used in the Wankel DKM54 test engine with a compression ratio of 8:1; it ran without complaint. This upset the petrochemical industry in Europe, which had invested considerable sums of money in new plants for the production of higher quality gasoline. Direct injection stratified charge engines can be operated with fuels with particularly low octane numbers. Such as diesel fuel, which only has an octane number of ~25. As

6396-400: A turbocharged 13B Rotary or 2.0-liter V6 engines, electric leather seats, digital speedometer, a cool-box for canned beverages, prominent emblems, electronically adjustable suspension and power options throughout. In order to satisfy Japanese regulations concerning exterior dimensions and engine displacement, this generation vehicle was built in two versions; the 3.0-liter V6 was installed in

6560-624: Is compressed rather than protruded , or simply unrounded. Some Japanese consonants have several allophones , which may give the impression of a larger inventory of sounds. However, some of these allophones have since become phonemic. For example, in the Japanese language up to and including the first half of the 20th century, the phonemic sequence /ti/ was palatalized and realized phonetically as [tɕi] , approximately chi ( listen ) ; however, now [ti] and [tɕi] are distinct, as evidenced by words like tī [tiː] "Western-style tea" and chii [tɕii] "social status". The "r" of

6724-448: Is also seen in o-medetō "congratulations", from medetaku ). Late Middle Japanese has the first loanwords from European languages – now-common words borrowed into Japanese in this period include pan ("bread") and tabako ("tobacco", now "cigarette"), both from Portuguese . Modern Japanese is considered to begin with the Edo period (which spanned from 1603 to 1867). Since Old Japanese,

6888-527: Is also used in a limited fashion (such as for imported acronyms) in Japanese writing. The numeral system uses mostly Arabic numerals , but also traditional Chinese numerals . Proto-Japonic , the common ancestor of the Japanese and Ryukyuan languages , is thought to have been brought to Japan by settlers coming from the Korean peninsula sometime in the early- to mid-4th century BC (the Yayoi period ), replacing

7052-643: Is an agglutinative , mora -timed language with relatively simple phonotactics , a pure vowel system, phonemic vowel and consonant length, and a lexically significant pitch-accent . Word order is normally subject–object–verb with particles marking the grammatical function of words, and sentence structure is topic–comment . Sentence-final particles are used to add emotional or emphatic impact, or form questions. Nouns have no grammatical number or gender , and there are no articles . Verbs are conjugated , primarily for tense and voice , but not person . Japanese adjectives are also conjugated. Japanese has

7216-440: Is appropriate to use sensei ( 先生 , "teacher"), but inappropriate to use anata . This is because anata is used to refer to people of equal or lower status, and one's teacher has higher status. Japanese nouns have no grammatical number, gender or article aspect. The noun hon ( 本 ) may refer to a single book or several books; hito ( 人 ) can mean "person" or "people", and ki ( 木 ) can be "tree" or "trees". Where number

7380-701: Is associated with comedy (see Kansai dialect ). Dialects of Tōhoku and North Kantō are associated with typical farmers. The Ryūkyūan languages, spoken in Okinawa and the Amami Islands (administratively part of Kagoshima ), are distinct enough to be considered a separate branch of the Japonic family; not only is each language unintelligible to Japanese speakers, but most are unintelligible to those who speak other Ryūkyūan languages. However, in contrast to linguists, many ordinary Japanese people tend to consider

7544-466: Is better documentation of Late Middle Japanese phonology than for previous forms (for instance, the Arte da Lingoa de Iapam ). Among other sound changes, the sequence /au/ merges to /ɔː/ , in contrast with /oː/ ; /p/ is reintroduced from Chinese; and /we/ merges with /je/ . Some forms rather more familiar to Modern Japanese speakers begin to appear – the continuative ending - te begins to reduce onto

7708-509: Is correlated with the sex of the speaker and the social situation in which they are spoken: men and women alike in a formal situation generally refer to themselves as watashi ( 私 , literally "private") or watakushi (also 私 , hyper-polite form), while men in rougher or intimate conversation are much more likely to use the word ore ( 俺 "oneself", "myself") or boku . Similarly, different words such as anata , kimi , and omae ( お前 , more formally 御前 "the one before me") may refer to

7872-558: Is depicted in figure 7. Seals at the rotor's apices seal against the housing's periphery. The rotor moves in its rotating motion guided by gears and the eccentric output shaft, not being guided by the external chamber. The rotor does not make contact with the external engine housing. The force of expanded gas pressure on the rotor exerts pressure on the center of the eccentric part of the output shaft. All practical Wankel engines are four-cycle (i.e., four-stroke) engines. In theory, two-cycle engines are possible, but they are impractical because

8036-428: Is described in the thermodynamic disadvantages section , the early Wankel engines had poor fuel economy. This is caused by the Wankel engine's design of combustion chamber shape and huge surface area. The Wankel engine's design is, on the other hand, much less prone to engine knocking, which allows using low- octane fuels without reducing compression. NSU tested low octane gasoline at the suggestion of Felix Wankel. On

8200-440: Is different from a four-stroke piston engine, which needs to make two full rotations per combustion chamber to complete all four phases of a four-stroke engine. Thus, in a Wankel rotary engine, according to Bensinger, displacement ( V h {\displaystyle V_{h}} ) is: If power is to be derived from BMEP, the four-stroke engine formula applies: Eugen Wilhelm Huber, and Karl-Heinz Küttner counted all

8364-417: Is important, it can be indicated by providing a quantity (often with a counter word ) or (rarely) by adding a suffix, or sometimes by duplication (e.g. 人人 , hitobito , usually written with an iteration mark as 人々 ). Words for people are usually understood as singular. Thus Tanaka-san usually means Mx Tanaka . Words that refer to people and animals can be made to indicate a group of individuals through

8528-504: Is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century AD recorded a few Japanese words, but substantial Old Japanese texts did not appear until the 8th century. From the Heian period (794–1185), extensive waves of Sino-Japanese vocabulary entered the language, affecting the phonology of Early Middle Japanese . Late Middle Japanese (1185–1600) saw extensive grammatical changes and

8692-755: Is less common. In terms of mutual intelligibility , a survey in 1967 found that the four most unintelligible dialects (excluding Ryūkyūan languages and Tōhoku dialects ) to students from Greater Tokyo were the Kiso dialect (in the deep mountains of Nagano Prefecture ), the Himi dialect (in Toyama Prefecture ), the Kagoshima dialect and the Maniwa dialect (in Okayama Prefecture ). The survey

8856-420: Is often called a topic-prominent language , which means it has a strong tendency to indicate the topic separately from the subject, and that the two do not always coincide. The sentence Zō wa hana ga nagai ( 象は鼻が長い ) literally means, "As for elephant(s), (the) nose(s) (is/are) long". The topic is zō "elephant", and the subject is hana "nose". Japanese grammar tends toward brevity; the subject or object of

9020-498: Is preserved in words such as matsuge ("eyelash", lit. "hair of the eye"); modern mieru ("to be visible") and kikoeru ("to be audible") retain a mediopassive suffix - yu(ru) ( kikoyu → kikoyuru (the attributive form, which slowly replaced the plain form starting in the late Heian period) → kikoeru (all verbs with the shimo-nidan conjugation pattern underwent this same shift in Early Modern Japanese )); and

9184-397: Is the number of chambers considered for each rotor and i {\displaystyle i} the number of rotors, then the total displacement is: If p m e {\displaystyle p_{me}} is the mean effective pressure , N {\displaystyle N} the shaft rotational speed and n c {\displaystyle n_{c}}

9348-402: Is the version of Japanese discussed in this article. Formerly, standard Japanese in writing ( 文語 , bungo , "literary language") was different from colloquial language ( 口語 , kōgo ) . The two systems have different rules of grammar and some variance in vocabulary. Bungo was the main method of writing Japanese until about 1900; since then kōgo gradually extended its influence and

9512-471: Is used for the present and the future. For verbs that represent an ongoing process, the -te iru form indicates a continuous (or progressive) aspect , similar to the suffix ing in English. For others that represent a change of state, the -te iru form indicates a perfect aspect. For example, kite iru means "They have come (and are still here)", but tabete iru means "They are eating". Questions (both with an interrogative pronoun and yes/no questions) have

9676-405: Is why some linguists do not classify Japanese "pronouns" as pronouns, but rather as referential nouns, much like Spanish usted (contracted from vuestra merced , "your ( majestic plural ) grace") or Portuguese você (from vossa mercê ). Japanese personal pronouns are generally used only in situations requiring special emphasis as to who is doing what to whom. The choice of words used as pronouns

Thus, all production Wankel engines are of the KKM type. Felix Wankel designed a rotary compressor in the 1920s, and received his first patent for

10332-738: The United States (notably in Hawaii , where 16.7% of the population has Japanese ancestry, and California ), and the Philippines (particularly in Davao Region and the Province of Laguna ). Japanese has no official status in Japan, but is the de facto national language of the country. There is a form of the language considered standard : hyōjungo ( 標準語 ) , meaning "standard Japanese", or kyōtsūgo ( 共通語 ) , "common language", or even "Tokyo dialect" at times. The meanings of

10496-806: The de facto standard Japanese had been the Kansai dialect , especially that of Kyoto . However, during the Edo period, Edo (now Tokyo) developed into the largest city in Japan, and the Edo-area dialect became standard Japanese. Since the end of Japan's self-imposed isolation in 1853, the flow of loanwords from European languages has increased significantly. The period since 1945 has seen many words borrowed from other languages—such as German, Portuguese and English. Many English loan words especially relate to technology—for example, pasokon (short for "personal computer"), intānetto ("internet"), and kamera ("camera"). Due to

Approximately 12% of Hawaii residents speak Japanese, with an estimated 12.6% of the population of Japanese ancestry in 2008. Japanese emigrants can also be found in Peru , Argentina , Australia (especially in the eastern states), Canada (especially in Vancouver , where 1.4% of the population has Japanese ancestry),

For a while, engineers were faced with what they called "chatter marks" and "devil's scratch" in the inner epitrochoid surface, resulting in chipping of the chrome coating of the trochoidal surfaces. They discovered that the cause was the apex seals reaching a resonating vibration, and the problem was solved by reducing the thickness and weight of the apex seals as well as using more suitable materials. Scratches disappeared after introducing more compatible materials for seals and housing coatings. Yamamoto experimentally lightened apex seals with holes. Now, weight

Curb weight was low at 1,188 kg (2,620 lb) and the wheelbase fairly short at 2,510 mm (99 in). The body was freshened in 1976. For the United States market, the RX-4 was sold from 1974 through 1978, when the RX-7 debuted. The 13B produced 110 hp (82 kW) and 159 N⋅m (117 lb⋅ft) in United States emissions form. Base pricing

The Potentia was produced from 1992 until 2002 using the 2.0-liter four-cylinder Mazda FE-DOHC engine — which was the same as used in the first generation Kia Sportage 's gasoline version —

11480-749: The Japanese Luce Rotary sold as the Mazda RX-4 . It was a larger car than its rotary -powered contemporaries, the Capella -based RX-2 and Grand Familia -based RX-3 . It used the Luce chassis, replacing the R130 in October 1972, and was produced through October 1977. Its predecessor (the R130) and replacement (the rotary Luce Legato ) were not sold in the United States. Mazda marketed the RX-4 as being sporty and luxurious " personal luxury car " with

11644-486: The Japanese language is of particular interest, ranging between an apical central tap and a lateral approximant . The "g" is also notable; unless it starts a sentence, it may be pronounced [ ŋ ] , in the Kanto prestige dialect and in other eastern dialects. The phonotactics of Japanese are relatively simple. The syllable structure is (C)(G)V(C), that is, a core vowel surrounded by an optional onset consonant,

11808-459: The KKM (see figure 5.). The KKM proved to be a much more practical engine, as it has easily accessible spark plugs, a simpler cooling design, and a conventional power take-off shaft. Wankel disliked Froede's KKM engine because of its inner rotor's eccentric motion, which was not a pure circular motion, as Wankel had intended. He remarked that his "race horse" was turned into a "plough horse". Wankel also complained that more stresses would be placed on

11972-488: The KKM ;502 was a powerful engine with decent potential, smooth operation, and low noise emissions at high engine speeds. It was a single-rotor PP engine with a displacement of 996 cm (61 in ), a rated power of 40 kW (54 hp) at 6,000   rpm and a BMEP of 1 MPa (145 lbf/in ). The Wankel engine has a spinning eccentric power take-off shaft, with a rotary piston riding on eccentrics on

12136-462: The KKM's apex seals due to the eccentric hula-hoop motion of the rotor. NSU could not afford to finance developing both the DKM and the KKM, and eventually decided to drop the DKM in favor of the KKM, because the latter seemed to be the more practical design. Wankel obtained the US patent 2,988,065 on the KKM engine on 13 June 1961. Throughout the design phase of the KKM, Froede's engineering team had to solve problems such as repeated bearing seizures,

12300-540: The LA42S with the 12A engine was manufactured between September 1977 and April 1978, while the larger LA43S with the 13B introduced at the same time lasted until October 1981. This generation sedan was not sold in North America. It was originally designated as the Luce Legato, but the Japanese automobile industry authorities would not allow for what they considered a name change and so it was officially sold as simply

12464-407: The Luce. The "L" for "Legato" suffix hung on though, with export models receiving the new car as the "929L". Legato is a musical term meaning "to make a smooth transition from one note to another" The rebodied Mazda Luce Legato became the second generation 929 in 1978 for export markets, often called the 929L. There was no coupé version developed of this generation, although a four-door hardtop body

12628-526: The Mazda RX-4. The conventionally-engined Luce sedan (LA2VS) would not arrive to the Japanese market until April 1973, after starting production in March. It was available as a hardtop (coupé), "formal sedan", "custom sedan", and as a station wagon which was also sold as a van in the domestic Japanese market. The original hardtop coupé received a longer, more aggressive front design, which was also installed on

12792-736: The Old Japanese sections are written in Man'yōgana , which uses kanji for their phonetic as well as semantic values. Based on the Man'yōgana system, Old Japanese can be reconstructed as having 88 distinct morae . Texts written with Man'yōgana use two different sets of kanji for each of the morae now pronounced き (ki), ひ (hi), み (mi), け (ke), へ (he), め (me), こ (ko), そ (so), と (to), の (no), も (mo), よ (yo) and ろ (ro). (The Kojiki has 88, but all later texts have 87. The distinction between mo 1 and mo 2 apparently

12956-401: The RX-4 having the best of both worlds. This gave Mazda a well needed boost in the popularity of the Wankel engine unique to Mazda. In Japan, the rotary-engined variants offered an advantage with regards to the annual road tax bill in that Japanese drivers paid less than the in-line engine equivalents, while receiving more performance from the rotary engine. The RX-4 was initially available as

13120-488: The Ryūkyūan languages as dialects of Japanese. The imperial court also seems to have spoken an unusual variant of the Japanese of the time, most likely the spoken form of Classical Japanese , a writing style that was prevalent during the Heian period , but began to decline during the late Meiji period . The Ryūkyūan languages are classified by UNESCO as 'endangered', as young people mostly use Japanese and cannot understand

13284-413: The United States market in 1970 with just the small R100 , but expanded to a full line in 1971. This included all three of the company's piston-powered models, the compact 1200 , mid-size 616 , and full-size 1800. The US-market 1800 produced 98 hp (99 PS; 73 kW) and 146 N⋅m (108 lb⋅ft) and cost US$ 2,280 . Performance with the three-speed automatic transmission was sluggish, with

13448-453: The Wankel engine has lower thermal efficiency and higher exhaust emissions relative to the four-stroke reciprocating piston engine. The thermal inefficiency has restricted the engine to limited use since its introduction in the 1960s. However, many disadvantages have mainly been overcome over the succeeding decades as the production of road-going vehicles progressed. The advantages of compact design, smoothness, lower weight, and fewer parts over

13612-443: The Wankel engine run much smoother. This is because the Wankel engine has a lower moment of inertia and less excess torque area due to its more uniform torque delivery. For example, a two-rotor Wankel engine runs more than twice as smoothly as a four-cylinder piston engine. The eccentric output shaft of a Wankel engine also does not have the stress-related contours of a reciprocating piston engine's crankshaft. The maximum revolutions of

13776-543: The addition of a collective suffix (a noun suffix that indicates a group), such as -tachi , but this is not a true plural: the meaning is closer to the English phrase "and company". A group described as Tanaka-san-tachi may include people not named Tanaka. Some Japanese nouns are effectively plural, such as hitobito "people" and wareware "we/us", while the word tomodachi "friend" is considered singular, although plural in form. Verbs are conjugated to show tenses, of which there are two: past and present (or non-past) which

13940-506: The assistance of Prof. Othmar Baier  [ de ] from Stuttgart University of Applied Sciences, the concept was defined mathematically. The supercharger he designed was used for one of NSU's 50 cm one-cylinder two-stroke engines. The engine produced a power output of 13.5 PS (10 kW) at 12,000   rpm. In 1954, NSU agreed to develop a rotary internal combustion engine with Felix Wankel, based upon Wankel's supercharger design for their motorcycle engines. Since Wankel

14104-613: The average torque, with the shaft running at 2/3 the speed, operating the Otto cycles at the same frequency: Applying a 2/3 gear set to the output shaft of the three-cylinder (or a 3/2 one to the Wankel), the two are analogous from the thermodynamic and mechanical output point of view, as pointed out by Huber. NSU licensed the Wankel engine design to companies worldwide, in various forms, with many companies implementing continual improvements. In his 1973 book Rotationskolben-Verbrennungsmotoren , German engineer Wolf-Dieter Bensinger describes

14268-422: The axially closer side housings in the cooler intake lobe areas was dealt with by using an axial rotor pilot radially inboard of the oils seals, plus improved inertia oil cooling of the rotor interior (C-W US 3261542   , C. Jones, 5/8/63, US 3176915   , M. Bentele, C. Jones. A.H. Raye. 7/2/62), and slightly "crowned" apex seals (different height in the center and in the extremes of seal). As

14432-407: The chambers, since each one operates its own thermodynamic cycle. So y = 3 {\displaystyle y=3} and n c = 3 {\displaystyle n_{c}=3} : With these values, a single-rotor Wankel engine produces the same average power as a V h {\displaystyle V_{h}} three-cylinder four-stroke engine, with 3/2 of

14596-438: The custom sedan. The formal sedan and the van/wagon received a somewhat shorter front end which was also used on the export versions (929). For the facelifted LA3 model from 1976, only one front design was used—one with a more square design. While the Luce was a large, luxuriously equipped sedan, it still complied to Japanese Government dimension regulations , and it wasn't the largest sedan Mazda sold in Japan. That honor went to

14760-523: The design is described to have a displacement V h of 250 cm (equivalent to a working chamber volume V k of 125 cm ). The fourth unit built is said to have received several design changes, and eventually produced 29 PS (21 kW) at 17,000 rpm; it could reach speeds up to 22,000 rpm. One of the four engines built has been on static display at the Deutsches Museum Bonn (see figure. 2). Due to its complicated design with

14924-448: The early days, unique, dedicated production machines had to be built for different housing dimensional arrangements. However, patented designs such as U.S. patent 3,824,746 , G. J. Watt, 1974, for a "Wankel Engine Cylinder Generating Machine", U.S. patent 3,916,738 , "Apparatus for machining and/or treatment of trochoidal surfaces" and U.S. patent 3,964,367 , "Device for machining trochoidal inner walls", and others, solved

15088-578: The effect of changing Japanese into a mora-timed language. Late Middle Japanese covers the years from 1185 to 1600, and is normally divided into two sections, roughly equivalent to the Kamakura period and the Muromachi period , respectively. The later forms of Late Middle Japanese are the first to be described by non-native sources, in this case the Jesuit and Franciscan missionaries; and thus there

15252-416: The engine's torque production. Early closing of the intake port increases low-end torque, but reduces high-end torque (and thus power). In contrast, late closing of the intake port reduces low-end torque while increasing torque at high engine speeds, thus resulting in more power at higher engine speeds. A peripheral intake port gives the highest mean effective pressure ; however, side intake porting produces

15416-431: The engine. While this puts great demands on the materials used, the simplicity of the Wankel makes it easier to use alternative materials, such as exotic alloys and ceramics . A commonplace method is, for engine housings made of aluminum, to use a spurted molybdenum layer on the engine housing for the combustion chamber area, and a spurted steel layer elsewhere. Engine housings cast from iron can be induction-brazed to make

15580-421: The experience gained, from carbon alloys, to steel, ferritic stainless , Ferro-TiC, and other materials. The combination of housing plating and the apex and side seal materials was determined experimentally, to obtain the best duration of both seals and housing cover. For the shaft, steel alloys with little deformation on load are preferred, the use of Maraging steel has been proposed for this. Leaded petrol fuel

15744-463: The factor that controls the amount of unburnt hydrocarbons in the exhaust is the rotor surface temperature, with higher temperatures resulting in fewer hydrocarbons in the exhaust. Curtiss-Wright widened the rotor, keeping the rest of engine's architecture unchanged, thus reducing friction losses and increasing displacement and power output. The limiting factor for this widening was mechanical, especially shaft deflection at high rotative speeds. Quenching

15908-404: The farthest, and a {\displaystyle a} as the shortest parallel transfer of the rotor and the inner housing and assuming that R 1 = R + a {\displaystyle R_{1}=R+a} and R 2 = R + a ′ {\displaystyle R_{2}=R+a'} . Then, Including the parallel transfers of the rotor and

16072-423: The first appearance of European loanwords . The basis of the standard dialect moved from the Kansai region to the Edo region (modern Tokyo ) in the Early Modern Japanese period (early 17th century–mid 19th century). Following the end of Japan's self-imposed isolation in 1853, the flow of loanwords from European languages increased significantly, and words from English roots have proliferated. Japanese

16236-529: The following licensees, in chronological order, which is confirmed by John B. Hege: In 1961, the Soviet research organizations of NATI, NAMI, and VNIImotoprom began developing a Wankel engine. Eventually, in 1974, development was transferred to a special design bureau at the AvtoVAZ plant. John B. Hege argues that no license was issued to any Soviet car manufacturer. Felix Wankel managed to overcome most of

16400-609: The genitive particle ga remains in intentionally archaic speech. Early Middle Japanese is the Japanese of the Heian period , from 794 to 1185. It formed the basis for the literary standard of Classical Japanese , which remained in common use until the early 20th century. During this time, Japanese underwent numerous phonological developments, in many cases instigated by an influx of Chinese loanwords . These included phonemic length distinction for both consonants and vowels , palatal consonants (e.g. kya ) and labial consonant clusters (e.g. kwa ), and closed syllables . This had

16564-503: The higher-spec 929S model for the 1990–1991 period, the engine was upgraded to a Double Overhead Cam type with 24 valves, slightly increasing fuel economy , performance and reliability. Also in the revised edition came the presence of an anti-lock braking system , ventilated rear disc brakes and a few inconspicuous changes to the exterior. The standard 18-valve SOHC remained in the base model 929. After mainstream production ended in May 1991,

16728-449: The inner housing provides sufficient accuracy for determining chamber volume. Different approaches have been used over time to evaluate the total displacement of a Wankel engine in relation to a reciprocating engine: considering only one, two, or all three chambers. Part of this dispute was because of Europe vehicle taxation being dependent on engine displacement, as reported by Karl Ludvigsen . If y {\displaystyle y}

16892-536: The intake gas and the exhaust gas cannot be properly separated. The operating principle is similar to the Otto operating principle; the Diesel operating principle with its compression ignition cannot be used in a practical Wankel engine. Therefore, Wankel engines typically have a high-voltage spark ignition system. In a Wankel engine, one side of the triangular rotor completes the four-stage Otto cycle of intake, compression, expansion, and exhaust each revolution of

17056-458: The languages of the original Jōmon inhabitants, including the ancestor of the modern Ainu language . Because writing had yet to be introduced from China, there is no direct evidence, and anything that can be discerned about this period must be based on internal reconstruction from Old Japanese , or comparison with the Ryukyuan languages and Japanese dialects . The Chinese writing system

17220-449: The languages. Okinawan Japanese is a variant of Standard Japanese influenced by the Ryūkyūan languages, and is the primary dialect spoken among young people in the Ryukyu Islands . Modern Japanese has become prevalent nationwide (including the Ryūkyū islands) due to education , mass media , and an increase in mobility within Japan, as well as economic integration. Japanese is a member of

17384-427: The large quantity of English loanwords, modern Japanese has developed a distinction between [tɕi] and [ti] , and [dʑi] and [di] , with the latter in each pair only found in loanwords. Although Japanese is spoken almost exclusively in Japan, it has also been spoken outside of the country. Before and during World War II , through Japanese annexation of Taiwan and Korea , as well as partial occupation of China ,

17548-471: The longer and wider hardtop bodystyle, and the smaller engines, including the rotary engine, were installed in the shorter and narrower sedan bodystyle. Japanese owners who chose the rotary engine received financial benefits in a lower annual road tax bill over trim packages with the larger V6 engine. It was the larger model that carried over to the next platform that introduced the Mazda Sentia . 1991

17712-414: The material suited for withstanding combustion heat stress. Among the alloys cited for Wankel housing use are A-132, Inconel 625, and 356 treated to T6 hardness. Several materials have been used for plating the housing working surface, Nikasil being one. Citroën, Daimler-Benz, Ford, A P Grazen, and others applied for patents in this field. For the apex seals, the choice of materials has evolved along with

17876-430: The number of shaft revolutions needed to complete a cycle ( N / n c {\displaystyle N/n_{c}} is the frequency of the thermodynamic cycle), then the total power output is: Kenichi Yamamoto and Walter G. Froede placed y = 1 {\displaystyle y=1} and n c = 1 {\displaystyle n_{c}=1} : With these values,

18040-546: The oil flow inside the engine, and the engine cooling. The first fully functioning KKM engine, the KKM 125, weighing in at only 17 kg (37.5 lb) displaced 125 cm and produced 26 PS (19 kW) at 11,000   rpm. Its first run was on 1 July 1958. In 1963, NSU produced the first series-production Wankel engine for a car, the KKM 502 (see Figure 6.). It was used in the NSU Spider sports car, of which about 2,000 were made. Despite its "teething troubles",

18204-609: The only country where it is the national language , and within the Japanese diaspora worldwide. The Japonic family also includes the Ryukyuan languages and the variously classified Hachijō language . There have been many attempts to group the Japonic languages with other families such as the Ainu , Austronesian , Koreanic , and the now-discredited Altaic , but none of these proposals have gained any widespread acceptance. Little

18368-425: The only strict rule of word order is that the verb must be placed at the end of a sentence (possibly followed by sentence-end particles). This is because Japanese sentence elements are marked with particles that identify their grammatical functions. The basic sentence structure is topic–comment . For example, Kochira wa Tanaka-san desu ( こちらは田中さんです ). kochira ("this") is the topic of the sentence, indicated by

18532-506: The other hand, the same ignition timing of L and T leads to a higher energy conversion. Hydrocarbons adhering to the combustion chamber wall are expelled into the exhaust at the peripheral outlet. Mazda used 3 spark plugs in their R26B engine per chamber. The third spark plug ignites the mixture in the trailing side before the squish is generated, causing the mixture to burn completely and, also speeding up flame propagation, which improves fuel consumption. According to Curtiss-Wright research,

18696-470: The out-group gives a benefit to the in-group, and "up" to indicate the in-group gives a benefit to the out-group. Here, the in-group includes the speaker and the out-group does not, and their boundary depends on context. For example, oshiete moratta ( 教えてもらった ) (literally, "explaining got" with a benefit from the out-group to the in-group) means "[he/she/they] explained [it] to [me/us]". Similarly, oshiete ageta ( 教えてあげた ) (literally, "explaining gave" with

18860-415: The particle wa . The verb desu is a copula , commonly translated as "to be" or "it is" (though there are other verbs that can be translated as "to be"), though technically it holds no meaning and is used to give a sentence 'politeness'. As a phrase, Tanaka-san desu is the comment. This sentence literally translates to "As for this person, (it) is Mx Tanaka." Thus Japanese, like many other Asian languages,

19024-482: The performance of Wankel engines. Side intake ports (as used in Mazda's Renesis engine) were first proposed by Hanns-Dieter Paschke in the late 1950s. Paschke predicted that precisely calculated intake ports and intake manifolds could make a side port engine as powerful as a PP engine. As formerly described, the Wankel engine is affected by unequal thermal expansion due to the four cycles taking place in fixed places of

19188-409: The piston-engined second generation Mazda Luce. The first generation Luce had been called the "Mazda 1500" or "Mazda 1800" in export markets, but as engines of different displacement were beginning to be used across lines, such a naming philosophy would have soon become confusing. The 929/Luce was a large (for Japan) coupé , sedan , and station wagon powered by a 1769 cc Mazda VB engine . Output

19352-463: The problem. Wankel engines have a problem not found in reciprocating piston four-stroke engines in that the block housing has intake, compression, combustion, and exhaust occurring at fixed locations around the housing. This causes a very uneven thermal load on the rotor housing. In contrast, four-stroke reciprocating engines perform these four strokes in one chamber, so that extremes of "freezing" intake and "flaming" exhaust are averaged and shielded by

19516-421: The problems that made prior attempts to perfect the rotary engines fail, by developing a configuration with vane seals having a tip radius equal to the amount of "oversize" of the rotor housing form, relative to the theoretical epitrochoid, to minimize radial apex seal motion plus introducing a cylindrical gas-loaded apex pin which abutted all sealing elements to seal around the three planes at each rotor apex. In

19680-481: The proposed larger Altaic family, or to various Southeast Asian languages , especially Austronesian . None of these proposals have gained wide acceptance (and the Altaic family itself is now considered controversial). As it stands, only the link to Ryukyuan has wide support. Other theories view the Japanese language as an early creole language formed through inputs from at least two distinct language groups, or as

19844-408: The reciprocating piston internal combustion engines make the Wankel engine suited for applications such as chainsaws , auxiliary power units (APUs), loitering munitions , aircraft , jet skis , snowmobiles , and range extenders in cars . The Wankel engine was also used to power motorcycles and racing cars . The Wankel engine is a type of rotary piston engine and exists in two primary forms,

20008-429: The rotor (equivalent to three shaft revolutions, see Figure 8.). The shape of the rotor between the fixed apexes is to minimize the volume of the geometric combustion chamber and maximize the compression ratio , respectively. As the rotor has three sides, this gives three power pulses per revolution of the rotor. Wankel engines have a much lower degree of irregularity relative to a reciprocating piston engine, making

20172-410: The rotor housing and determined by the generating radius R {\displaystyle R} , the rotor width B {\displaystyle B} , and the parallel transfers of the rotor and the inner housing a {\displaystyle a} . Since the rotor has a trochoid ("triangular") shape, the sine of 60 degrees describes the interval at which the rotors get closest to

20336-443: The rotor housing. Therefore, The rotor path s {\displaystyle s} may be integrated via the eccentricity e {\displaystyle e} as follows: Therefore, For convenience, a {\displaystyle a} may be omitted because it is difficult to determine and small: A different approach to this is introducing a ′ {\displaystyle a'} as

20500-482: The same power as the regular versions. This was complemented and then replaced by the larger 13B in December 1973 producing 135 PS (99 kW). This model has 125 PS (92 kW), for export. This engine was Mazda's new "AP" (for "anti-pollution") version, with much-improved emissions and fuel economy, but somewhat worse cold-starting behavior. In South Africa it was produced until 1979, all years only with

20664-459: The same structure as affirmative sentences, but with intonation rising at the end. In the formal register, the question particle -ka is added. For example, ii desu ( いいです ) "It is OK" becomes ii desu-ka ( いいですか。 ) "Is it OK?". In a more informal tone sometimes the particle -no ( の ) is added instead to show a personal interest of the speaker: Dōshite konai-no? "Why aren't (you) coming?". Some simple queries are formed simply by mentioning

20828-407: The same. The Wankel engine has a significantly higher (Δt K >100 K) exhaust gas temperature than an Otto engine, especially under low and medium load conditions. This is because of the higher combustion frequency and slower combustion. Exhaust gas temperatures can exceed 1300 K under high load at engine speeds of 6000 rpm . To improve the exhaust gas behavior of the Wankel engine,

20992-406: The shaft in a hula-hoop fashion. The Wankel is a 2:3 type of rotary engine, i.e., its housing's inner side resembles a two lobes oval-like epitrochoid (equivalent to a peritrochoid),. In contrast, its rotary piston has a three vertices trochoid shape (similar to a Reuleaux triangle ). Thus, the Wankel engine's rotor constantly forms three moving working chambers. The Wankel engine's basic geometry

21156-520: The short-lived Mazda Roadpacer , which was based on GM Australia's Holden Premier . The LA2VV station wagon entered production in September 1973. The wagon lasted until 1979, until being replaced by the LA4 wagon. Two rotary engines were offered, the regular 12A and low-emission AP 13B. There were also piston models available, and van models for the Japanese market. Engines: In most export markets,

21320-500: The smaller 12A engine. Engines: The next generation of Luce was built on the HB platform . Production started in October 1981. Exports again occurred as the 929. Japanese customers could purchase the Luce or the rebadged Mazda Cosmo sold at an exclusive dealership called "Mazda Auto Store". Later in 1991, Mazda Auto locations were renamed Eunos . Unlike the Luce, the Cosmo was also sold as

21484-506: The sportiest flip-up headlight "Cosmo" design for 929 coupés. No station wagon variant was issued on the HB platform; the previous LA4 remained in production as a wagon with a new front end (it was essentially the same as the LA4 from the A-pillar backwards). This generation vehicle was not sold in North America. In some European markets the 929 was badged 2000 sedan or 2000E estate (applied to

21648-817: The state as at the time the constitution was written, many of the elders participating in the process had been educated in Japanese during the South Seas Mandate over the island shown by the 1958 census of the Trust Territory of the Pacific that found that 89% of Palauans born between 1914 and 1933 could speak and read Japanese, but as of the 2005 Palau census there were no residents of Angaur that spoke Japanese at home. Japanese dialects typically differ in terms of pitch accent , inflectional morphology , vocabulary , and particle usage. Some even differ in vowel and consonant inventories, although this

21812-481: The street. (grammatically incorrect insertion of a pronoun) But one can grammatically say essentially the same thing in Japanese: 驚いた彼は道を走っていった。 Transliteration: Odoroita kare wa michi o hashitte itta. (grammatically correct) This is partly because these words evolved from regular nouns, such as kimi "you" ( 君 "lord"), anata "you" ( あなた "that side, yonder"), and boku "I" ( 僕 "servant"). This

21976-488: The time had an octane index of 95 RON (up to 100 RON today). Also the manual transmission with four gears used in Europe contributed to a much better performance than the three-speed automatic transmission usually used in the US. The 1800 (fitted with a manual transmission) also sold in small numbers in Australia. The number of Mazda 1800 automobiles imported into the US are as follows. The 1800 four-door sedan (model SVA)

22140-460: The time of the generational change, the diesel engine was also installed in the van (wagon) model, only available with the GL equipment level. Aside from the regular piston-engined variants, the 12A or 13B rotary engines were on offer. The piston-engined variants were exported as the Mazda 929. A rotary-engined version was exported to "general issue" countries and sold as an RX-9. Most RX-9s were sold with

22304-481: The time, it was also available with a three-speed automatic transmission. The Luce Mark I was sold in Australia and most other export markets under the names "Mazda 1500" and "Mazda 1800". Mazda considered assembling the Luce in South Africa and brought in 50 examples for evaluation and company use in 1967, but they instead chose to focus on the 1200 (Familia) and compact pickup trucks. The Mazda brand entered

22468-571: The topic with an interrogative intonation to call for the hearer's attention: Kore wa? "(What about) this?"; O-namae wa? ( お名前は？ ) "(What's your) name?". Negatives are formed by inflecting the verb. For example, Pan o taberu ( パンを食べる。 ) "I will eat bread" or "I eat bread" becomes Pan o tabenai ( パンを食べない。 ) "I will not eat bread" or "I do not eat bread". Plain negative forms are i -adjectives (see below) and inflect as such, e.g. Pan o tabenakatta ( パンを食べなかった。 ) "I did not eat bread". Wankel engine In its basic gasoline fuelled form,

22632-419: The two consonants are the moraic nasal followed by a homorganic consonant. Japanese also includes a pitch accent , which is not represented in moraic writing; for example [haꜜ.ɕi] ("chopsticks") and [ha.ɕiꜜ] ("bridge") are both spelled はし ( hashi ) , and are only differentiated by the tone contour. Japanese word order is classified as subject–object–verb . Unlike many Indo-European languages ,

22796-577: The two methods were both used in writing until the 1940s. Bungo still has some relevance for historians, literary scholars, and lawyers (many Japanese laws that survived World War II are still written in bungo , although there are ongoing efforts to modernize their language). Kōgo is the dominant method of both speaking and writing Japanese today, although bungo grammar and vocabulary are occasionally used in modern Japanese for effect. The 1982 state constitution of Angaur , Palau , names Japanese along with Palauan and English as an official language of

22960-480: The two terms (''hyōjungo'' and ''kyōtsūgo'') are almost the same. Hyōjungo or kyōtsūgo is a conception that forms the counterpart of dialect. This normative language was born after the Meiji Restoration ( 明治維新 , meiji ishin , 1868) from the language spoken in the higher-class areas of Tokyo (see Yamanote ). Hyōjungo is taught in schools and used on television and in official communications. It

23124-512: The uneven thermal distribution within the housings causing distortion and loss of sealing and compression. This thermal distortion also caused uneven wear between the apex seal and the rotor housing, evident on higher mileage engines. The problem was exacerbated when the engine was stressed before reaching operating temperature . However, Mazda Wankel engines solved these initial problems. Current engines have nearly 100 seal-related parts. The problem of clearance for hot rotor apexes passing between

23288-407: The verb (e.g. yonde for earlier yomite ), the -k- in the final mora of adjectives drops out ( shiroi for earlier shiroki ); and some forms exist where modern standard Japanese has retained the earlier form (e.g. hayaku > hayau > hayɔɔ , where modern Japanese just has hayaku , though the alternative form is preserved in the standard greeting o-hayō gozaimasu "good morning"; this ending

23452-548: The world. Since Japanese first gained the consideration of linguists in the late 19th century, attempts have been made to show its genealogical relation to languages or language families such as Ainu , Korean , Chinese , Tibeto-Burman , Uralic , Altaic (or Ural-Altaic ), Austroasiatic , Austronesian and Dravidian . At the fringe, some linguists have even suggested a link to Indo-European languages , including Greek , or to Sumerian . Main modern theories try to link Japanese either to northern Asian languages, like Korean or

23616-460: Was $ 4295, with the automatic transmission ($ 270) and air conditioning ($ 395) the only expensive options. All three bodystyles were on offer in the United States. Road & Track magazine was impressed, noting the car's improved fuel economy and price compared to the RX-3. This was notable, as the Wankel engine had suffered by the mid 1970s with a reputation as a gas-guzzler. Performance was good in

23780-550: Was 16.9 seconds. This model was styled by Giorgetto Giugiaro , then working for Bertone , as a front-wheel-drive two-door coupé with front disc brakes, which was similar to the NSU Ro 80 . This model, Mazda's only front-wheel-drive rotary, is now a collector's item and very rare. Less than 1,000 were built. Mazda released a second generation LA2 series Luce in November 1972—a rotary powered model that would be later exported as

23944-453: Was 94 PS (69 kW) and 137 N⋅m (101 lb⋅ft). The Luce/929 was updated in 1975 with an optional 1970 cc engine which produced 103 PS (76 kW) and 167 N⋅m (123 lb⋅ft) from a two-barrel carburetor . Engines: The Luce Legato (introduced as the LA4 series in October 1977) was a large and luxurious sedan, still powered by Mazda's piston or rotary engines. It

24108-486: Was added in December 1968. This new model, the Luce 1800, produced 104 PS (76 kW) at 5500 rpm and 152 N⋅m (112 lb⋅ft) at 2500 rpm. To accommodate the taller 1800 engine the bonnet on this model has a slight bump in the middle with an air inlet on the leading edge. An estate ( station wagon ) was also added in April 1967, with the same engine as the sedan (SUAV). Unlike most commercial vehicles at

24272-515: Was also available as a four-door pillarless hardtop that looked like a huge, square coupé, and a wagon, which had more of a utilitarian role than the sedans. The coupé was replaced by the Mazda Cosmo (CD) . Production of the Luce 1800 (LA4VS) and 2000 (LA4MS) sedans started in October 1977, ending in July (LA4VS) and September 1981 (LA4MS) for the Japanese market. Of the rotary-engined Luce sedans,

24436-657: Was also exported under the 929 nameplate. The name " lu'ce " was taken from the Italian word for "light". Following an agreement signed with Bertone in April 1962, the 1965 Luce 1500 show car was designed by Giorgetto Giugiaro of Italy. It was low and sharp, looking more like a contemporary BMW Bavaria than its smaller Mazda companion models, the Familia and the kei car Carol . The production version (SUA), started production in July 1966 and launched in August, had

24600-528: Was also updated in 1986 (1987 in some markets) with the HC platform and a 3.0-liter V6 engine . The car was produced through 1991, again lagging behind its Japan-market twin, the Mazda Luce, by one year. The 929 began U.S. and Canadian sales in 1987; although predominantly available as a 3.0-liter V6, there were a rare few that made it to the North American market as a four-cylinder 2.2-liter F2 in

24764-427: Was an option, but most North American 929s were two-mode ('power' and 'economy') electronic four-speed automatics. Top speed was 195 km/h (121 mph). A 0–97 km/h (60 mph) time of 9.2 seconds was recorded using the manual gearbox; the automatics were somewhat slower at 10 seconds. The first 3.0-liter V6 engine seen in the 1986–1989 929 was a Single Overhead Cam type with 18 valves. When Mazda released

24928-474: Was available in Japan and some other markets including France. A station wagon was added in February 1979. The design was American-inspired, with stacked rectangular headlights and a large chrome grille. The rather heavy and old-fashioned exterior was made to look even older by having a very up-to-date interior and dashboard. In Europe, a more efficient 2.0-liter inline-four, producing 90 PS (66 kW) with

25092-447: Was available paired to a 5 speed manual gearbox. It was a large front-engine rear-wheel drive sedan or hardtop sedan. The Luce was built on the new HB platform , which was now shared with the Cosmo. This version was introduced as the 929 in 1982 in most export markets and produced until 1986. Luces and Cosmos received several differing front end treatments, with export 929s receiving the very staidest front end designs for 929 sedans and

25256-539: Was based on 12- to 20-second-long recordings of 135 to 244 phonemes , which 42 students listened to and translated word-for-word. The listeners were all Keio University students who grew up in the Kanto region . There are some language islands in mountain villages or isolated islands such as Hachijō-jima island , whose dialects are descended from Eastern Old Japanese . Dialects of the Kansai region are spoken or known by many Japanese, and Osaka dialect in particular

25420-484: Was based on the Mazda Sentia and was introduced in 1997 after the Sentia was cancelled. The New Potentia was realigned in the marketplace and was now offered with a narrower range of engines and transmissions. The manual transmission, always a slow seller in South Korea, was discontinued and the engines were limited to a 2.0-liter four and a 2.5-liter V6. There was also an LPG-powered 2-liter four available. The New Potentia

25584-456: Was considered as having a better performance with 104 PS (76 kW) at 5500 rpm (SAE) and maximum torque of 148 N⋅m (109 lb⋅ft) at 3000 rpm (SAE), for a 0 to 60 mph (0 to 97 km/h) time of 13.4 seconds. The poor performance of this engine in USA was probably due to fact that in USA, the gasoline had an octane index of only 85 RON, while in Europe, the gasoline at

25748-456: Was identified as the main cause. Mazda then used aluminum-impregnated carbon apex seals in their early production engines. NSU used carbon antimony-impregnated apex seals against chrome. NSU developed ELNISIL coating to production maturity and returned to a metal sealing strip for the RO80. Mazda continued to use chrome, but provided the aluminum housing with a steel jacket, which was then coated with

25912-735: Was imported to Japan from Baekje around the start of the fifth century, alongside Buddhism. The earliest texts were written in Classical Chinese , although some of these were likely intended to be read as Japanese using the kanbun method, and show influences of Japanese grammar such as Japanese word order. The earliest text, the Kojiki , dates to the early eighth century, and was written entirely in Chinese characters, which are used to represent, at different times, Chinese, kanbun , and Old Japanese. As in other texts from this period,

26076-499: Was known as a "difficult colleague", the development work for the DKM was carried out at Wankel's private Lindau design bureau. According to John B. Hege, Wankel received help from his friend Ernst Höppner, who was a "brilliant engineer". The first working prototype, DKM 54 (see figure 2.), first ran on 1 February 1957, at the NSU research and development department Versuchsabteilung TX . It produced 21 PS (15 kW). Soon after that,

26240-474: Was lost immediately following its composition.) This set of morae shrank to 67 in Early Middle Japanese , though some were added through Chinese influence. Man'yōgana also has a symbol for /je/ , which merges with /e/ before the end of the period. Several fossilizations of Old Japanese grammatical elements remain in the modern language – the genitive particle tsu (superseded by modern no )

26404-451: Was produced from October 1968 through March 1973 where a reported 39,401 units were made. An 1800 station wagon version (model SVAV) was added in 1968, lasting until 1970. A rotary -powered Luce appeared in 1969. The Luce R130 was produced from October 1969 to 1972. It used a 1.3-liter 13A engine, which produced 126 PS (93 kW; 124 hp) and 17.5 kg⋅m (172 N⋅m; 127 lb⋅ft). Quarter-mile (400 meters) performance

26568-666: Was the last year of the Luce nameplate. The Eunos Cosmo was already on sale ( JC ), and the HD platform spawned the Mazda Sentia (now exported as the 929), and the Efini MS-9 , making 1991 the last year for a four-door rotary powered sedan prior to the RX-8 . In the 1990s Mazda sold the body stampings to Kia Motors who produced the HC series as Kia Potentia between 1992 and 2001—selling it only in South Korea . The export market 929

26732-573: Was the predominant type available in the first years of the Wankel engine's development. Lead is a solid lubricant, and leaded petrol is designed to reduce the wearing of seals and housings. The first engines had the oil supply calculated with consideration of petrol's lubricating qualities. As leaded petrol was being phased out, Wankel engines needed an increased mix of oil in the petrol to provide lubrication to critical engine parts. An SAE paper by David Garside extensively described Norton's choices of materials and cooling fins. Early engine designs had

26896-578: Was unable to compete with the more modern Hyundai Grandeur and the Samsung SM5 and was partially replaced by the somewhat smaller Kia Optima beginning in 2000; the Potentia remained in production until May 2002. Japanese language Japanese ( 日本語 , Nihongo , [ɲihoŋɡo] ) is the principal language of the Japonic language family spoken by the Japanese people . It has around 123 million speakers, primarily in Japan ,
