111-552: The Volkswagen Corrado is a compact four passenger (2+2), three door, front-engine, front-wheel-drive liftback coupe marketed by Volkswagen from 1988 until 1995, and manufactured by Karmann in Osnabrück , Germany. Designed by Herbert Schäfer, the Corrado overlapped and eventually superseded Volkswagen's Scirocco model. 97,521 Corrados were manufactured over the seven year production run; about 50,000 of them were sold in
222-405: A hot-bulb engine used a 'jerk pump' to dispense fuel oil at high pressure to an injector. Another development in early diesel engines was the pre-combustion chamber, which was invented in 1919 by Prosper l'Orange to avoid the drawbacks of air-blast injection systems. The pre-combustion chamber made it feasible to produce engines in size suitable for automobiles and MAN Truck & Bus presented
333-632: A spark plug . The Cummins Model H diesel truck engine was introduced in America in 1933. In 1936, the Mercedes-Benz OM 138 diesel engine (using a precombustion chamber) became one of the first fuel-injected engines used in a mass-production passenger car. During World War II , several petrol engines for aircraft used direct-injection systems, such as the European Junkers Jumo 210 , Daimler-Benz DB 601 , BMW 801 , and
444-417: A transverse engine , rather than the conventional longitudinal engine arrangement generally found in rear-wheel-drive and four-wheel-drive vehicles. By far the most common layout for a front-wheel-drive car is with the engine and transmission at the front of the car, mounted transversely. Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally,
555-454: A carburettor. Many of the carburettor's supporting components—such as the air filter, intake manifold, and fuel line routing—could be used with few or no changes. This postponed the redesign and tooling costs of these components. Single-point injection was used extensively on American-made passenger cars and light trucks during 1980–1995, and in some European cars in the early and mid-1990s. In the US,
666-581: A central injector instead of multiple injectors. Single-point injection (also called 'throttle-body injection') uses one injector in a throttle body mounted similarly to a carburettor on an intake manifold . As in a carburetted induction system, the fuel is mixed with the air before entering the intake manifold. Single-point injection was a relatively low-cost way for automakers to reduce exhaust emissions to comply with tightening regulations while providing better "driveability" (easy starting, smooth running, no engine stuttering) than could be obtained with
777-562: A cheaper, and even more successful Trumpf Junior model, which sold over 100,000 in August 1939, and in the same year Citroën introduced the very successful Traction Avant models in France, over time selling them in the hundred thousands. Hupmobile made 2 experimental models with front-wheel drive in 1932 and 1934, but neither came into production In the late 1930s, the Cord 810/812 of
888-555: A colour keyed front grille, an additional Storm badge on the gear gaiter surround (an upgrade from the standard Karmann badge), 15 inch BBS "Solitude" alloy wheels, and standard fitment of some previously optional items (such as the leather heated front seats) differentiated this model from the base Corrado VR6. Only five hundred were produced: 250 in Classic Green with a cream leather interior, and 250 in Mystic Blue,
999-579: A colour unique to the Storm, with a black leather interior. An extremely rare special edition based on the VR6, named the Corrado Campaign was launched and produced in 1992. Only six cars were produced with just four cars surviving as of 2022. The Campaign model was unique with Dusty Mauve Pearl Effect paint and a red brick leather interior. They were built as a prize as part of a dealer incentive to sell
1110-456: A flexibly located electronically controlled cooling fan. This configuration was pioneered by Dante Giacosa in the 1964 Autobianchi Primula and popularized with the Fiat 128 . Fiat promoted in its advertising that mechanical features consumed only 20% of the vehicle's volume and that Enzo Ferrari drove a 128 as his personal vehicle. The 1959 Mini used a substantially different arrangement with
1221-456: A front-wheel-drive system for motorising horse-drawn carts. In 1899 the inventor Henry Sutton designed and built one of Australia's first cars, called The Sutton Autocar. This car may have been the first front-wheel-drive car in the world. Henry's car was reported in the English press at the time and featured in the English magazine Autocar , after which the car was named. Two prototypes of

#17327877539271332-572: A fuel injection system are described in the following sections. In some systems, a single component performs multiple functions. Fuel injection is operated by spraying pressurised fuel into the engine. Therefore a device to pressurise the fuel is needed, such as a fuel pump. The system must determine the appropriate amount of fuel to be supplied and control the fuel flow to supply this amount. Several early mechanical injection systems used relatively sophisticated helix-controlled injection pump(s) that both metered fuel and created injection pressure. Since
1443-728: A fuel injection system in 1941 and by 1956 it was used in the Jaguar racing cars. At the 1957 24 Hours of Le Mans , the 1st to 4th placed cars were Jaguar D-Type entries using a Lucas fuel injection system. Also in 1957, General Motors introduced the Rochester Ramjet option, consisting of a fuel injection system for the V8 engine in the Chevrolet Corvette. During the 1960s, fuel injection systems were also produced by Hilborn , SPICA and Kugelfischer . Up until this time,
1554-441: A massive increase in grip and handling over all but the most expensive cars on the market. It initially used flexing rubber instead of needle rollers at the inboard universal joints of the driveshafts but later changed to needle rollers, and GKN designed constant-velocity joint at each outboard end of the drive shafts to allow for steering movement. The Mini revived the use of front-wheel drive which had been largely abandoned since
1665-433: A mid-engine layout and a rear-engine layout. Experiments with front-wheel-drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot 's 1769/1770 "fardier à vapeur" , was a front-wheel-driven three-wheeled steam-tractor. It then took at least a century for the first experiments with mobile internal combustion engines to gain traction. Sometime between 1895 and 1898
1776-471: A more powerful transverse engine: accordingly, faster versions featured longitudinally mounted (north–south) engines. Despite these developments, however, by the end of the 1980s, almost all major European and Japanese manufacturers had converged around the Fiat-pioneered system of a transversely mounted engine with an "end-on" transmission with unequal length driveshafts. For example, Renault dropped
1887-580: A passenger car was released the following year, in the Mercedes-Benz 300SL sports car. However the engine suffered lubrication problems due to petrol diluting the engine oil, and subsequent Mercedes-Benz engines switched to a manifold injection design. Likewise, most petrol injection systems prior to the 2000s used the less-expensive manifold injection design. Throughout the 1950s, several manufacturers introduced their manifold injection systems for petrol engines. Lucas Industries had begun developing
1998-483: A pulsed flow system which used an air flow meter to calculate the amount of fuel required. L-Jetronic was widely adopted on European cars during the 1970s and 1980s. As a system that uses electronically-controlled fuel injectors which open and close to control the amount of fuel entering the engine, the L-Jetronic system uses the same basic principles as modern electronic fuel injection (EFI) systems. Prior to 1979,
2109-399: A sophisticated common-rail injection system. The latter is the most common system in modern automotive engines. During the 20th century, most petrol engines used either a carburettor or indirect fuel injection. Use of direct injection in petrol engines has become increasingly common in the 21st century. In a common rail system, fuel from the fuel tank is supplied to a common header (called
2220-576: A transverse-mounted engine behind the front axle. This design would continue for 3 decades in Germany. Buckminster Fuller adopted rear-engine, front-wheel drive for his three Dymaxion Car prototypes. Other German car producers followed: Stoewer offered a car with front-wheel drive in 1931, Adler in 1932 and Audi in 1933. Versions of the Adler Trumpf sold five-figure numbers from 1932 to 1938, totalling over 25,600 units. In 1934, Adler added
2331-758: A transversely installed engine was the Suzuki Suzulight , which was a small "city" car, called a kei car in Japanese. In 1955, the Polish producer FSO in Warsaw introduced the front-wheel-driven Syrena of its own design. In 1959 Austin Mini was launched by the British Motor Corporation , designed by Alec Issigonis as a response to the first oil crisis, the 1956 Suez Crisis , and

The name Victoria Combination described the lightweight, two-seater trailer commonly known as a Victoria, combined with the rear axle and drive mechanism from a motor tricycle that was placed in front to achieve front wheel drive. It also known as the Eureka . By 1899 Victoria Combinations were participating in motoring events such as

This can be done either with a blast of air or hydraulically, with the latter method being more common in automotive engines. Typically, hydraulic direct injection systems spray fuel into the air inside the cylinder or combustion chamber. Direct injection can be achieved with a conventional helix-controlled injection pump, unit injectors, or
2664-546: Is called a manifold injection system. There exist two types of manifold injection systems: multi-point injection (or port injection) and single-point injection (or throttle body injection). Internal mixture formation systems can be separated into several different varieties of direct and indirect injection, the most common being the common-rail injection system, a variety of direct injection. The term "electronic fuel injection" refers to any fuel injection system controlled by an engine control unit . The fundamental functions of
2775-533: Is injected at the same time to all the cylinders; or cylinder-individual , in which the engine control unit can adjust the injection for each cylinder individually. Multi-point injection (also called 'port injection') injects fuel into the intake ports just upstream of each cylinder's intake valve , rather than at a central point within an intake manifold. Typically, multi-point injected systems use multiple fuel injectors, but some systems, such as GM's central port injection system, use tubes with poppet valves fed by
2886-461: Is named for the G Lader with which it is equipped, a scroll-type supercharger whose interior resembles the letter "G". Sales were initially slow, as the Corrado was considerably more expensive than the Scirocco it was meant to replace. Volkswagen United States stated that they had "overequipped the Corrado" when first introduced, leading to sluggish sales. There were also two special models of

Except for Citroën, after the 1930s, front-wheel drive would largely be abandoned for the following twenty years. Save the interruption of World War II , Citroën built some 3 ⁄ 4 million Traction Avants through 1957; adding their cheap 2CV people's car in 1948, and introducing an equally front-wheel driven successor for

This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines ), and many spark-ignition engines (i.e. petrol (gasoline) engines , such as Otto or Wankel ), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as

There were relatively few rear-wheel-drive cars marketed in North America by the early 1990s; Chrysler 's car line-up was entirely front-wheel drive by 1990. GM followed suit in 1996 where its B-body line was phased out, where its sports cars (Camaro, Firebird, Corvette) were the only RWDs marketed; by the early 2000s, the Chevrolet Corvette and Cadillac Catera were
3441-492: The Douvrin engines used in the larger Renaults (20, 21, 25 and 30) used this longitudinal "forward" layout. The Saab Saab 99 , launched in 1968, also used a longitudinal engine with a transmission underneath with helical gears. The 1966 Oldsmobile Toronado was the first U.S. front-wheel-drive car since the Cord 810 . It used a longitudinal engine placement for its V8, coupled with an unusual "split" transmission, which turned

In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes
3885-620: The Prince Motor Company also developed a transmission-in-sump type layout for its first front wheel drive model, which after the company's takeover by Nissan , emerged as the Datsun 100A (Cherry) in 1971. In 1960 Lancia could evolve the project CemsaF11 of Antonio Fessia with the innovative Lancia Flavia for first time with motor Boxer on auxiliary frame for low centre of gravity. This scheme continued in Lancia until 1984 with

Six years before the appearance of the Citroën Traction Avant and more than two years before the launch of the DKW F1, the Bucciali TAV-6 featured front-wheel drive. Both German makers DKW in 1931 and Adler in 1933 bought Tracta licenses for their first front-wheel-drive cars. Imperia in Belgium and Rosengart in France manufactured
4329-479: The Wankel engine . In a manifold injection system, air and fuel are mixed outside the combustion chamber so that a mixture of air and fuel is sucked into the engine. The main types of manifold injections systems are multi-point injection and single-point injection . These systems use either a continuous injection or an intermittent injection design. In a continuous injection system, fuel flows at all times from
4440-669: The accumulator ), and then sent through tubing to the injectors, which inject it into the combustion chamber. The accumulator has a high-pressure relief valve to maintain pressure and return the excess fuel to the fuel tank. The fuel is sprayed with the help of a nozzle that is opened and closed with a solenoid-operated needle valve . Third-generation common rail diesels use piezoelectric injectors for increased precision, with fuel pressures up to 300 MPa or 44,000 psi . The types of common-rail systems include air-guided injection and spray-guided injection . Used by diesel engines, these systems include: This injection method
4551-437: The throttle body . Fuel injectors which also control the metering are called "injection valves", while injectors that perform all three functions are called unit injectors . Direct injection means that the fuel is injected into the main combustion chamber of each cylinder. The air and fuel are mixed only inside the combustion chamber. Therefore, only air is sucked into the engine during the intake stroke. The injection scheme

The transversely mounted engine combined with front-wheel drive was popularized by the 1959 Mini ; there the transmission was built into the sump of the engine, and drive was transferred to it via a set of primary gears . Another variant transmission concept was used by Simca in the 1960s keeping the engine and transmission in line, but transverse mounted and with unequal length driveshafts. This has proven itself to be

The two-stroke, two-cylinder motor was mounted transversely in the front and connected to the front wheels through a four-speed synchronised gearbox. The high price and lacklustre performance doomed its production. Only 600 units were produced from 1946 to 1950. In 1946 in Italy, Antonio Fessia created his Cemsa Caproni F11 , with 7 examples produced. His innovation

Lancia, however also made front-wheel drive its flagship even in sport cars as the winner of the Rally, Lancia Fulvia , and then with large-scale models with excellent road qualities and performances including Lancia Beta , Lancia Delta , Lancia Thema including the powerful Lancia Thema 8.32 with engine Ferrari and all subsequent models. Ford introduced front-wheel drive to its European customers in 1962 with
7881-439: The engine and gearbox to be located side by side without sharing lubricating fluid while orienting the cooling fan toward fresh air flow. By using the Primula as a test-bed, Fiat was able to sufficiently resolve the layout's disadvantages, including uneven side-to-side power transmission, uneven tire wear and potential torque steer , the tendency for the power of the engine alone to steer the car under heavy acceleration. The problem
7992-807: The engine compartment – the Alfa Romeo Alfasud (and its replacement, the 1983 Alfa 33 as well as the Alfa 145/146 up to the late 1990s) also used the same layout. Honda also introduced several small front-wheel drive vehicles, with the N360 and N600 , the Z360 and Z600 in 1967, the Honda 1300 in 1969, followed by the Honda Civic in 1972 and the Honda Accord in 1976. Also in the 1970s and 1980s,
8103-412: The engine driving the front wheels through an offset final drive and unequal-length driveshafts, combined with MacPherson struts and an independently located radiator – subsequently became common with competitors and arguably an industry standard. The Corporate Average Fuel Economy standard drove a mass changeover of cars in the U.S. to front-wheel drive. The change began in 1978, with
8214-517: The engine power 180 degrees. Power then went to a differential mounted to the transmission case, from which half-shafts took it to the wheels. The driveline was set fairly at centre-point of the wheels for better weight distribution, though this raised the engine, requiring lowered intake systems. Little known outside of Italy, the Primula is today primarily known for innovating the modern economy-car layout. – Hemmings Motor News , August 2011 Front-wheel-drive layout had been highly impacted by
8325-533: The engine. The layout often required the engine be removed to service the clutch. This Active Tourer MPV wants to be more stable than a BMW M3, and using the Dante Giacosa-pattern front-wheel-drive layout compacts the mechanicals and saves space for people in the reduced overall length of what will surely become a production 1-series tall-sedan crossover. – Robert Cumberford , Automobile Magazine , March 2013 As engineered by Dante Giacosa ,
8436-441: The first direct-injected diesel engine for trucks in 1924. Higher pressure diesel injection pumps were introduced by Bosch in 1927. In 1898, German company Deutz AG started producing four-stroke petrol stationary engines with manifold injection. The 1906 Antoinette 8V aircraft engine (the world's first V8 engine) was another early four-stroke engine that used manifold injection. The first petrol engine with direct-injection
8547-402: The front axles of almost every four-wheel or all-wheel drive vehicle. Neither automobile was particularly successful in the open market. In spite of the Cord's hallmark innovation, using CV joints, and being competitively priced against contemporaneous alternatives, the buyers demographic were expecting more than the car's 80 mph (130 km/h) top speed, and combined with the effect of
8658-655: The fuel injection systems had used a mechanical control system. In 1957, the American Bendix Electrojector system was introduced, which used analogue electronics for the control system. The Electrojector was intended to be available for the Rambler Rebel mid-size car, however reliability problems meant that the fuel injection option was not offered. In 1958, the Chrysler 300D , DeSoto Adventurer , Dodge D-500 and Plymouth Fury offered
8769-580: The fuel injectors, but at a variable flow rate. The most common automotive continuous injection system is the Bosch K-Jetronic system, introduced in 1974 and used until the mid-1990s by various car manufacturers. Intermittent injection systems can be sequential , in which injection is timed to coincide with each cylinder's intake stroke; batched , in which fuel is injected to the cylinders in groups, without precise synchronization to any particular cylinder's intake stroke; simultaneous , in which fuel
8880-633: The fuel through a small nozzle under high pressure, while carburetion relies on suction created by intake air accelerated through a Venturi tube to draw fuel into the airstream. The term "fuel injection" is vague and comprises various distinct systems with fundamentally different functional principles. Typically, the only thing all fuel injection systems have in common is a lack of carburetion . There are two main functional principles of mixture formation systems for internal combustion engines: internal mixture formation and external mixture formation. A fuel injection system that uses external mixture formation
8991-493: The introduction of the first American-built transverse-engined cars, the Plymouth Horizon and Dodge Omni (based on the European designed Simca Horizon ), followed by the 1980 Chevrolet Citation and numerous other vehicles. Meanwhile, European car makers, that had moved to front-wheel drive decades before, began to homogenize their engine arrangement only in this decade, leaving Saab , Audi (and Volkswagen ) as
9102-503: The main combustion chamber. Therefore, this principle is called indirect injection. There exist several slightly different indirect injection systems that have similar characteristics. Types of indirect injection used by diesel engines include: In 1872, George Bailey Brayton obtained a patent on an internal combustion engine that used a pneumatic fuel injection system, also invented by Brayton: air-blast injection . In 1894, Rudolf Diesel copied Brayton's air-blast injection system for
9213-527: The model on which almost all modern FWD vehicles are now based. Peugeot and Renault on their jointly developed small car engine of the 1970s where the 4-cylinder block was canted over to reduce the overall height of the engine with the transmission mounted on the side of the crankcase in what became popularly known as the "suitcase" arrangement ( PSA X engine ). The tendency of this layout to generate unwanted transmission "whine" has seen it fall out of favour. Also, clutch changes required engine removal. In Japan,
9324-606: The model range. The Corrado is noted for its flush mounted windows and active rear spoiler – which raises automatically when the car exceeds 100 km/h (62 mph) (45 mph or 72 km/h in the North American market), automatically retracts at speeds below 25 km/h (15 mph) or can be manually controlled by the driver. The name Corrado was derived from the Spanish verb "correr", meaning to run or sprint. Prototypes were named Taifun (German for "Typhoon") but
9435-653: The most Karmann-produced vehicles and all six cars were given to the top six dealerships in the United Kingdom as a bonus. The Corrado was offered in Japan at Yanase dealerships that specialize in North American and European vehicles, offering the 1.8 L engine with either the automatic or manual transmission. The larger VR6 would have been considerably more expensive to tax, as the engine was over two liters' displacement. Auto Express magazine describe it as "Regarded as one of VW’s best ever drivers’ cars". The VR6 model
9546-476: The name was changed prior to release. Launched in the end of 1988 (three years before the end of Scirocco production), all Corrados were front-wheel drive and featured petrol engines . The Corrado debuted with two engine choices: a 1.8 litre 16-valve inline four with 136 PS (100 kW; 134 hp) ( KR ), and a supercharged 1.8 litre eight valve inline four, marketed as the G60 and delivering 160 PS (118 kW; 158 hp). The Corrado G60
9657-637: The only RWD cars offered by General Motors until the introduction of the Sigma platform . After the phaseout of the Ford Panther platform (except for the Mustang), Ford automobiles (including the Transit Connect van) manufactured for the 2012 model year to present are front-wheel drive; its D3 platform (based on a Volvo platform) has optional all-wheel drive. Fuel injection Fuel injection
9768-604: The only manufacturers offering a front-drive longitudinal engine layout. Years before this was the most common layout in Europe, with examples like Citroën DS , Renault 12 , Renault 5 , Renault 25 (a Chrysler LH ancestor) Alfa Romeo 33 , Volkswagen Passat , etc. This transition can be exemplified in the Renault 21 that was offered with disparate engine configurations. The 1.7-litre version featured an "east–west" (transversely) mounted engine, but Renault had no gearbox suitable for
9879-963: The pre-war DKW F8 and F9 reappeared as the IFA F8 and IFA F9 in 1949, followed by the AWZ P70 in 1955, the Wartburg 311 in 1956 and the Trabant in 1958, all with front-wheel drive. The P70 and Trabant had Duroplast bodies, and the Trabant had both a monocoque body and a transversely mounted engine, a modern design in some ways. In 1950 West German makers also reintroduced front-wheel-drive cars: DKW had lost its production facilities in Eisenach (now in DDR) and reestablished itself in Ingolstadt. A version of
9990-570: The pre-war F9 was introduced as the DKW F89. Borgward introduced 2 new makes with front-wheel drive, the Goliath and the Lloyd in 1950. Gutbrod also came with a car in 1950; the Superior, but withdrew the car in 1954 and concentrated on other products. This car is best remembered for its Bosch fuel-injection . In 1955, one of the first Japanese manufacturers to utilize front-wheel drive with
10101-725: The public, and a few months later the Ruxton automobile . The Cord L-29's drive system was again inspired by racing, copying from the Indianapolis 500 -dominating racers, using the same de Dion layout and inboard brakes. Moreover, the Auburn (Indiana) built Cord was the first ever front-wheel drive production car to use constant-velocity joints . These very specific components allow motive power to be delivered to steered wheels more seamlessly than universal joints , and have become common on almost every front-wheel-drive car, including on
10212-520: The same transverse-mounted, forward-motor layout as modern front-wheel-drive automobiles. It even resembled the smaller version of its popular Alfa Romeo Giulia . However, due to the financial difficulties in post-war Italy, the 33 never saw production. Had Alfa-Romeo succeed in producing 33, it would have preceded the Mini as the first "modern" European front-wheel-drive compact car. The German car industry resumed from WW2 in 1949/1950. In East Germany (DDR),
10323-494: The space previously occupied by four cylinder engines, while closely approaching the smoothness of a straight six design. 1994 was the last model year of the Corrado in the United States. A lower cost, 2.0-litre 8-valve model with 115 PS (85 kW; 113 hp) was produced for Europe from 1993 until 1995. A limited edition only for the United Kingdom, the Corrado Storm, was also sold. Some discreet "Storm" badging,
10434-426: The styling with a new front grill and foglamps. With the introduction of the VR6 engine, the G60 engine disappeared from the North American market after 1992 and European market in 1993. The VR6 engine provided a compromise between both V-shaped and straight engines by placing the two cylinder banks at an angle of 15°, with a single cylinder head. This design allowed engineers to fit a six cylinder engine into roughly
10545-471: The success of small, inexpensive cars, especially the British Mini . As engineered by Alec Issigonis , the compact arrangement located the transmission and engine sharing a single oil sump – despite disparate lubricating requirements – and had the engine's radiator mounted to the side of the engine, away from the flow of fresh air and drawing heated rather than cool air over
10656-418: The transmission in the sump, and the cooling fan drawing hot air from its side-facing location. Volvo Cars has switched its entire lineup after the 900 series to front-wheel drive. Swedish engineers at the company have said that transversely mounted engines allow for more crumple zone area in a head-on collision. American auto manufacturers are now shifting larger models (such as the Chrysler 300 and most of
10767-586: The transmission-in-sump " Suitcase " engine that it had co-developed with Peugeot in the 1970s for its compact models, starting with the Renault 9 in 1982. Peugeot-Citroen themselves also moved over to the end-on gearbox solution when it phased out the Suitcase unit in favour of the TU-series engine in 1986. Nissan also abandoned the transmission-in-sump concept for its N12-series Cherry/Pulsar in 1982. Perhaps symbolically, British Leyland themselves, heirs to
10878-473: The use of constant velocity jointed drive axles, along with front wheel drive has evolved into the modern-day mass-market automobile. Some suggest that the introduction of the modern Volkswagen Golf in 1974, from a traditional U.S. competitor, and the introduction of the 1973 Honda Civic , and the 1976 Honda Accord served as a wake-up call for the "Big Three" (only Chrysler already produced front-wheel-drive vehicles in their operations outside North America). GM
10989-424: Was a two-stroke aircraft engine designed by Otto Mader in 1916. Another early spark-ignition engine to use direct-injection was the 1925 Hesselman engine , designed by Swedish engineer Jonas Hesselman. This engine could run on a variety of fuels (such as oil, kerosene, petrol or diesel oil) and used a stratified charge principle whereby fuel is injected towards the end of the compression stroke, then ignited with
11100-407: Was another early digital fuel injection system. These and other electronic manifold injection systems (using either port injection or throttle-body injection ) became more widespread through the 1980s, and by the early 1990s they had replaced carburettors in most new petrol-engined cars sold in developed countries. The aforementioned injection systems for petrol passenger car engines - except for
11211-481: Was appreciated within the enthusiast community, the model never saw series production. It is generally believed that only two factory built examples were manufactured, both in Nugget Yellow. Volkswagen introduced two new engines for 1992. The first was a naturally aspirated 2.0 litre, 16-valve 136 PS (100 kW; 134 hp) inline-four, basically a further development of the 1.8-litre engine; this engine
11322-493: Was even later with the 1979 Vauxhall Astra / Opel Kadett . Captive imports were the US car makers initial response to the increased demand for economy cars . The popularity of front-wheel drive began to gain momentum, with the 1981 Ford Escort , the 1982 Nissan Sentra , and the 1983 Toyota Corolla . Front-wheel drive became the norm for mid-sized cars starting with the 1982 Chevrolet Celebrity , 1982 Toyota Camry , 1983 Dodge 600 , 1985 Nissan Maxima , 1986 Honda Legend , and
11433-488: Was held at the Indianapolis Motor Speedway on Saturday, 30 May 1925. However, the idea of front-wheel drive languished outside the motor racing arena as few manufacturers attempted the same for production automobiles. Alvis Cars did introduce a commercial model of the front-wheel drive 12/50 racer in 1928, but it was not a success. In France, Jean-Albert Grégoire and Pierre Fenaille developed
11544-486: Was largely solved by making the shorter driveshaft solid, and the longer one hollow, to ensure both shafts experienced elastic twist which was roughly the same. After the 128, Fiat further demonstrated the layout's flexibility, re-configurating the 128 drive train as a mid-engined layout for the Fiat X1/9 . The compact, efficient Giacosa layout – a transversely-mounted engine with transmission mounted beside
11655-562: Was listed as one of the "25 Cars You Must Drive Before You Die" by the British magazine Car , and 'By far the most desirable version of the Corrado' by Auto Express . In MSN Autos 'Cool Cars We Miss' feature they listed the Corrado among the top eight "Gone but not forgotten: a short list of cars once loved, still missed", describing it in the following manner: "The VW Corrado VR6 is coveted because of its seductive styling, road handling capabilities and its role as trailblazer, introducing
11766-418: Was never made available to the North American market. The second was the 12-valve VR6 engine , which came in two variants: a 2.8-litre 178 hp (133 kW; 180 PS) model for the United States and Canadian markets, and a 2,861 cc (2.9 L; 174.6 cu in) producing 190 PS (187 bhp; 140 kW) at 5,800 rpm and 245 N⋅m (181 lbf⋅ft) at 4,200 rpm of torque version for
11877-453: Was previously used in many diesel engines. Types of systems include: The M-System , used in some diesel engines from the 1960s to the 1980s, sprayed the fuel onto the walls of the combustion chamber, as opposed to most other direct-injection systems which spray the fuel into the middle of the chamber. Manifold injection systems are common in petrol-fuelled engines such as the Otto engine and
11988-473: Was the Fiat Multijet straight-four engine, introduced in the 1999 Alfa Romeo 156 1.9 JTD model. Since the 2010s, many petrol engines have switched to direct-injection (sometimes in combination with separate manifold injectors for each cylinder). Similarly, many modern diesel engines use a common-rail design. Stratified charge injection was used in several petrol engines in the early 2000s, such as
12099-642: Was the Lohner–Porsche of 1897 with an electric motor in each front wheel, produced by Lohner-Werke in Vienna. It was developed by Ferdinand Porsche in 1897 based on a concept developed by American inventor Wellington Adams . Porsche also raced it in 1897. J. Walter Christie of the United States patented a design for a front-wheel-drive car, the first prototype of which he built in 1904. He promoted and demonstrated several such vehicles, notably with transversely mounted engines, by racing at various speedways in
12210-605: Was the supercharged Alvis 12/50 racing car designed by George Thomas Smith-Clarke and William M. Dunn of Alvis Cars of the United Kingdom. This vehicle was entered in the 1925 Kop Hill Climb in Princes Risborough in Buckinghamshire on 28 March 1925. Harry Arminius Miller of Menomonie, Wisconsin designed the Miller 122 front-wheel drive race-car that was entered in the 1925 Indianapolis 500 , which
12321-401: Was to create the happy combination of a low centre of gravity boxer engine (flat four) with a special frame. Due to post-war financial problems Cemsa could not continue production, but the project was resumed when taken on by Lancia in the 50s. In 1954, Alfa-Romeo had experimented with its first front-wheel-drive compact car named "33" (not related to the sports car similarly named "33"). It had
