111-448: It is a 60° 24-valve design with aluminum block and heads and sequential multi-port fuel injection . Most versions feature continuously variable cam phasing on both intake and exhaust valves and electronic throttle control . Other features include piston oil-jet capability, forged and fillet rolled crankshaft , sinter forged connecting rods , a variable-length intake manifold , twin knock control sensors and coil-on-plug ignition . It

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

Maximum engine speed is 6500 RPM. Premium unleaded fuel

555-569: A bid to acquire the entirety of Alfa Romeo and offer job guarantees to Italian workers, an offer that Ford was unwilling to match. It also did not hurt any of the parties involved that an acquisition by Fiat would keep Alfa Romeo in Italian hands. In 1986, the deal was concluded with Alfa Romeo merged with traditional rival Lancia into Fiat's Alfa Lancia Industriale S.p.A. Already in 1981, Alfa Romeo's then-President Ettore Massacesi had stated that Alfa would never use Fiat engines—the engines being, to

666-454: 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,

777-581: 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

888-594: A company called Fabral ( Fábrica Brasileira de Automóveis Alfa , "the Brazilian Alfa automobile factory") to build the Alfa Romeo 2000 there. After having received government approval, Matarazzo pulled out under pressure from Brazil's President Juscelino Kubitschek with the state-owned FNM company instead commenced building the car as the "FNM 2000" there in 1960. During the 1960s, Alfa Romeo concentrated on motorsports using production-based cars, including

999-572: 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

1110-728: 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,

1221-546: A large extent, Alfa Romeo's identity—but would be happy to cooperate fully with everything else. Models produced from the 1990 onwards combined Alfa's traditional virtues of avant-garde styling and sporting panache with the economic benefits of product rationalisation, and include a "GTA" version of the 147 hatchback, the Giugiaro -designed Brera , and a high-performance exotic called the 8C Competizione (named after one of Alfa's most successful prewar sports and racing cars,

1332-580: 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

1443-479: A plastic radiator header tank. It had also the lowest drag coefficient (Cd) in its class The same trend continued with the Alfetta 2000 and GTV, which had quirks such as 50:50 weight distribution , standard fit alloy wheels and transaxle .

In 1952, Alfa Romeo experimented with its first front-wheel-drive compact car, "Project 13–61". It had the same transverse-mounted, forward-motor layout as the modern front-wheel-drive automobile. Alfa Romeo made

1665-483: 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,

1776-450: A redesigned cooling system to target the hottest areas while also facilitating faster warm-up. They also incorporate engine start-stop technology, cylinder-deactivation, 2-stage oil pumps, and updated variable valve timing featuring intermediate park technology for late-intake valve closure. Both engines debuted in the 2016 Cadillac CT6 . Bore and stroke of 86 mm × 85.8 mm (3.39 in × 3.38 in) are used, along with

1887-564: A second attempt in the late 1950s based on Project 13–61. It was to be called Tipo 103 and resembled the smaller version of its popular Alfa Romeo Giulia. However, due to the financial difficulties in post-war Italy, the Tipo 103 never saw production. Had Alfa Romeo produced it, it would have preceded the Mini as the first "modern" front-wheel-drive compact car. In the mid-1950s, Alfa Romeo entered into an agreement with Brazil 's Matarazzo Group to create

1998-399: 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

The later B.A.T. 11 was based on the 8C Competizione. The Tipo 33 racing car, with its high-revving 2000 cc V8 engine became the basis for a number of different concept cars during the 1960s and 1970s, two of which ultimately resulted in production vehicles. Most made their appearances at

2220-488: A total of 150,722 vehicles at the company's three factories. On January 16, 2021, the operations of Fiat Chrysler Automobiles and Groupe PSA were merged to form Stellantis and the company was renamed Stellantis Italy. In spite of falling sales, Alfa Romeo CEO Jean-Philippe Imparato announced in 2021 that a new model would be launched every year between 2022 and 2026, starting with the much-delayed Tonale , with full electrification of new models from 2027. Alfa Romeo

2331-524: A total of about 112,000 units, which was significantly lower than Fiat CEO Marchionne's global sales target of 300,000. The company set about to achieve a sales target of 170,000 units in 2011, including 100,000 Giulietta and 60,000 MiTo models, but it actually sold 130,000 units that year. Its medium-term target was 500,000 units by 2014 including 85,000 from the North American market. In 2017 Alfa Romeo increased production by 62 percent, building

The engine is manufactured at Holden's Fishermans Bend engine factory in Port Melbourne, Australia, while GM Powertrain Sweden (formerly Saab Automobile Powertrain)

2775-413: Is always intermittent (either sequential or cylinder-individual). 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

2886-546: 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

2997-533: 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

4218-415: The Mercedes-Benz OM 138 ) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. 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

4329-515: The Second World War . In 1928, Nicola Romeo left, and in 1933 Alfa Romeo was rescued by the government, which then had effective control. Alfa Romeo became an instrument of Mussolini's Italy, a national emblem. During this period, it built bespoke vehicles for the wealthy, with bodies normally by Carrozzeria Touring or Pininfarina . This era peaked with the Alfa Romeo 2900B Type 35 racers. The Alfa factory (converted during wartime to

By the 1970s, Alfa Romeo was again in financial trouble, with the company running at about sixty percent of capacity in 1980. Since Alfa Romeo was controlled by the Italian government owned Istituto per la Ricostruzione Industriale (IRI), a deal was made where about a quarter of worker's salaries were paid through state unemployment agencies to allow Alfa's plants to idle for two weeks every two months. An aging product lineup and very low productivity combined with near-permanent industrial unrest and Italy's high inflation rates kept Alfa Romeo firmly in

7326-579: The Saturn Vue Hybrid. The 3.6L twin-turbocharged version for the 2014 Cadillac CTS and XTS was announced at the 2013 NYAS . The engine is rated at 420 hp (313 kW; 426 PS) of power at 5750 rpm and 430 lb⋅ft (583 N⋅m) of torque at 3500–4500 rpm (with 90% of torque being available at 2500–5500 rpm) and helps the CTS achieve 0–60 mph (0–97 km/h) time of 4.6 seconds with an 8-speed automatic transmission. In essence,

7437-567: The US Market as announced by Fiat CEO Sergio Marchionne after a series of rumours. North American sales resumed in October 2008, with the launch of the limited production 8C Competizione coupe with Alfa Romeo models being imported by Fiat's US subsidiary Chrysler. Also in 2008, Alfa Romeo and Chrysler were reported to be in discussions over the possibility of producing Alfa Romeo cars in some Chrysler manufacturing plants that had shut down due to

7548-570: The United States and Australia. A 2.8 L (2,792 cc) LP1 variant was introduced in the 2005 Cadillac CTS . It was also used on the Chinese 2008 CTS. It has a 89 mm × 74.8 mm (3.50 in × 2.94 in) bore and stroke, sequential multi-port fuel injection and a 10.0:1 compression ratio. The LP1 was built in St. Catharines, Ontario. Applications: This engine

7659-649: The aesthetics and performance of sport and luxury marques. Despite its strong brand image and relatively sizeable share of the high-performance auto market in Europe, by the 1970s, the company was operating at a loss, prompting IRI to sell it to Fiat Group in 1986. Alfa Romeo has since maintained its distinct identity and brand through several ownership changes, including Fiat's merger with the American Chrysler Group in 2014, forming Fiat Chrysler Automobiles (FCA), and FCA's subsequent merger in 2021 with

7770-443: The air intake system. Although liquid LPG injection generally produces more power, Holden justified vapour injection on the grounds of lower fuel consumption, lower CO 2 emissions, reduced pumping and parasitic losses, and start-up reliability in hot weather. The dedicated LPG LWR engine produced peak power and torque of 180 kW (245 PS; 241 hp) at 6000 rpm and 320 N⋅m (236 lb⋅ft) at 2000 rpm. The LWR engine

7881-589: The amount of fuel to be injected. In 1974, Bosch introduced the K-Jetronic system, which used a continuous flow of fuel from the injectors (rather than the pulsed flow of the D-Jetronic system). K-Jetronic was a mechanical injection system, using a plunger actuated by the intake manifold pressure which then controlled the fuel flow to the injectors. Also in 1974, Bosch introduced the L-Jetronic system,

7992-456: The basis of its JTS V6 engine . Applications: The 3.6 L; 217.5 cu in (3,564 cc) LY7 engine was developed primarily by Holden and introduced in the 2004 Holden VZ Commodore and 2004 Cadillac CTS sedan. It has a 10.2:1 compression ratio, Sequential multi-port fuel injection, and a bore and stroke of 94 mm × 85.6 mm (3.70 in × 3.37 in). Lower-powered versions only have variable cam phasing on

8103-501: The carburetted version. The SPICA system continued until the 1982 model year with the introduction of 2.0 liter Bosch electronic fuel injection . Mechanical variable valve timing was introduced in the Alfa Romeo Spider , sold in the U.S. in 1980. All Alfa Romeo Spider models from 1983 onward used electronic VVT. The 105 series Giulia was quite an advanced car, using technologies such as all-wheel disc brakes , and

8214-567: The city of Milan : A red cross, from the emblem of Milan , and the biscione , a big grass snake and a child emerging from its mouth—emblem of the House of Visconti , rulers of the city in the 14th century. The logo was originally designed in 1910 by a young Italian draughtsman from the A.L.F.A. technical office, Romano Cattaneo. In June 1910, the Società Anonima Darracq became Anonima Lombarda Fabbrica Automobili, and

8325-546: The company group's restructure and cost cutting. Instead, as reported by The Wall Street Journal in November 2009, Chrysler discontinued several Dodge and Jeep models while phasing in Alfa Romeo ones and the new Fiat 500. The next significant milestones in Alfa Romeo's North American return occurred in 2014, with the launch of the more affordable two-seater 4C coupe . That year, Fiat Group Automobiles S.p.A. confirmed that its original agreement with Mazda Motor Corporation, for

8436-417: The company was the 1910 24 HP , designed by Giuseppe Merosi , hired in 1909 for designing new cars more suited to the Italian market. Merosi would go on to design a series of new A.L.F.A. cars, with more powerful engines such as the 40–60 HP . A.L.F.A. ventured into motor racing , with drivers Franchini and Ronzoni competing in the 1911 Targa Florio with two 24-hp models. In 1914, an advanced Grand Prix car

8547-510: The company's existing car engines were produced in a vastly enlarged factory during the war. After the war, Romeo invested his war profits in acquiring locomotive and railway carriage plants in Saronno ( Costruzioni Meccaniche di Saronno ), Rome (Officine Meccaniche di Roma), and Naples (Officine Ferroviarie Meridionali), which were added to his A.L.F.A. ownership. Car production had not been considered at first, but resumed in 1919 since parts for

8658-603: The completion of 105 cars had remained at the A.L.F.A. factory since 1915. In 1920, the name of the company was changed to Alfa Romeo with the Torpedo 20–30 HP the first car to be so badged. Their first success came in 1920 when Giuseppe Campari won at Mugello and continued with second place in the Targa Florio driven by Enzo Ferrari . Giuseppe Merosi continued as head designer, and the company continued to produce solid road cars as well as successful race cars (including

8769-579: The diesel engine, but also improved it. He increased the air blast pressure from 4–5 kp/cm (390–490 kPa) to 65 kp/cm (6,400 kPa). In the meantime, the first manifold injection system was designed by Johannes Spiel in 1884, while working at Hallesche Maschinenfabrik in Germany. In 1891, the British Herbert-Akroyd oil engine became the first engine to use a pressurised fuel injection system. This design, called

8880-618: The earlier LY7 engine. It was first unveiled in May 2006, and the DI version was claimed to have 15% greater power, 8% greater torque, and 3% better fuel economy than its port-injected counterpart. The LLT engine has a compression ratio of 11.3:1, and has been certified by the SAE to produce 302 hp (225 kW; 306 PS) at 6300 rpm and 272 lb⋅ft (369 N⋅m) of torque at 5200 rpm on regular unleaded (87 octane) gasoline. This engine debuted on

8991-411: The electronics in fuel injection systems used analogue electronics for the control system. The Bosch Motronic multi-point fuel injection system (also amongst the first systems where the ignition system is controlled by the same device as the fuel injection system) was the first mass-produced system to use digital electronics . The Ford EEC-III single-point fuel injection system, introduced in 1980,

9102-441: 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

9213-408: The first vehicle to bear the new brand. Through the 1920s, Alfa Romeo produced several successful road and race cars, and was well represented in prominent European motorsport events, notably winning the inaugural Grand Prix in 1925. Nevertheless, the company soon faced financial troubles, leading to Romeo's contentious departure in 1928 and Italian government ownership in 1933. Under the control of

9324-655: 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

9435-580: 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

9546-633: 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

9657-620: The industrial organization Institute per la Ricostruzione Industriale (IRI), Alfa Romeo initially continued making its signature custom luxury vehicles, but following the financial hardship of World War II, shifted to mass-producing small vehicles. In 1954, it launched the Giulietta series of family cars and developed the Alfa Romeo Twin Cam engine , which would remain in production until 1994. Alfa Romeo became known for producing mass-market vehicles that nonetheless blended

9768-416: The inlet cam (LE0). Selected models also include variable exhaust. The engine weighs 370 lb (170 kg) as installed. This engine is produced in several locations: St. Catharines (Ontario), Flint Engine South (Michigan), Melbourne (Australia), Ramos Arizpe (Mexico), and Sagara (Japan) by Suzuki. Suzuki's engine designation is N36A . The dual-fuel 235 hp (175 kW; 238 PS) LW2 version

9879-503: 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

9990-407: The mechanical holdings arm of IRI and its predecessors owned Alfa Romeo since 1932. Prodi first approached fellow Italian manufacturer Fiat, which offered to start a joint venture with Alfa. Fiat withdrew its plan for a joint venture with Alfa Romeo when Ford put in an offer to acquire part of Alfa Romeo and restructure the company, while increasing its stake over time. However, Fiat chose to put in

10101-424: The most wins of any marque in the world. The company's name is a combination of the original name, "A.L.F.A." ("Anonima Lombarda Fabbrica Automobili" - “Anonymous Lombardy Automobile Factory”), and the last name of entrepreneur Nicola Romeo, who took control of the company in 1915. The first factory building of A.L.F.A. was in the first-place property of Società Anonima Italiana Darracq (SAID), founded in 1906 by

10212-564: The new alloy construction, transmission pairing, and first use in production were all undertaken in Detroit (and manufactured in St. Catharines, Ontario ). Holden was charged with developing smaller engines (Holden 3.2 LP1 and Saab 2.8 Turbo LP9) as well as their own Holden 3.6 and 3.0 HFV6 (called the Alloytec V6) for local models. Cadillac and Holden both tested variations of these engines in

10323-510: The prior generation is the hydraulic lash adjusters in the valvetrain. The LGX was benchmarked against the 3.7L VQ37VHR of the 2015 Infiniti Q40. Compression ratio is 11.5:1 and maximum engine speed is 7200 RPM. Compared to GM's LFX/LFY 3.6 L engine, the LGX features active fuel management, NVH enhancements and slightly more torque. The LGX was on Ward's 10 Best Engines for 2016. Sequential multi-port fuel injection Fuel injection

10434-526: The production of Macchi C.202 Folgore engines: the Daimler-Benz 600 series built under license) was bombed during the Second World War and struggled to return to profitability after the war. The luxury vehicles were out. Smaller, mass-produced vehicles began to be produced beginning with the 1954 model year, with the introduction of the Giulietta series of berline (saloons/sedans), coupes and open two-seaters. All three varieties shared what would become

10545-407: The red. Other creative measures were attempted to shore up Alfa, including an ultimately unsuccessful joint venture with Nissan endorsed by Alfa's then-president, Ettore Massacesi, and Prime Minister Francesco Cossiga . By 1986, IRI was suffering heavy losses—with Alfa Romeo having not been profitable for the last 13 years —and IRI president Romano Prodi put Alfa Romeo up for sale. Finmeccanica,

10656-766: The speculated manufacturing of a new Alfa Romeo Spider based on the Mazda MX-5 had been terminated mutually in December 2014. The proposed model for this joint venture became the Fiat 124 Spider convertible launched in 2015. In 2015, Alfa Romeo's return to this market was further bolstered by the automaker's display of the new Giulia at the Los Angeles Auto Show. In February 2017, Chrysler featured its Alfa Romeo brand exclusively in three ads during Super Bowl LI . Alfa Romeo's US importer, FCA US LLC , imports

10767-591: The twin-turbo 3.6L V6 is the forced-induction variant of the popular LFX V6 found in the Cadillac ATS, XTS, and SRX, among many other GM models, with several important upgrades, including: Applications: The LF4 is a higher-performance variant of the LF3 for use in the Cadillac ATS-V . Changes to the LF3 include: Applications: The LFR is a bi-fuel variant of the LFX, although multi-point fuel injection

10878-424: 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

10989-475: Was able to run on petrol and autogas . The LW2 engine was based on the low-output LE0 V6. It featured a factory-fitted dual-fuel system developed by IMPCO, different valves, and hardened titanium valve seats. This motor was available exclusively in Holden vehicles from 2005–2012. Applications: Holden WL Statesman , VZ Calais , VZ SV6 The 3.6 L (3,564 cc) LLT is a direct injected version based on

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

11211-527: Was built. 18 January 1968, saw a new company named "Industria Napoletana Costruzioni Autoveicoli Alfa Romeo-Alfasud S.p.A." being formed, 90% of which belonged to Alfa Romeo and 10% to Government controlled holding company Finmeccanica . This plant was built in the wake of France's 1968 protests and Italy's Hot Autumn and was never "properly started." The employees had mainly construction backgrounds and were not trained for factory work, while industrial relations were troublesome throughout. Absenteeism rates in

11322-630: Was derived from the direct-injected LLT for use in hybrids , using the two-mode system . Differences from the LLT included a slightly lower compression ratio, 11.3:1, and lower power and torque peaks. It was to debut in the 2009 Saturn Vue Hybrid, where it would have made 262 hp (195 kW; 266 PS) at 6100 rpm and 250 lb⋅ft (339 N⋅m) of torque at 4800 rpm. Fuel economy ratings would have been 6–8 km/L (17–23 mpg ‑imp ; 14–19 mpg ‑US ) in city, and 9–11 km/L (25–31 mpg ‑imp ; 21–26 mpg ‑US ) on highway. However, GM cancelled its plans for

11433-637: Was designed and built, the GP1914 , with a four-cylinder engine, double overhead camshafts, four valves per cylinder, and twin ignition. However, the onset of the First World War halted automobile production at A.L.F.A. for three years. In August 1915, the company came under the direction of Neapolitan entrepreneur Nicola Romeo , who converted the factory to produce military hardware for the Italian and Allied war efforts. Munitions, aircraft engines and other components, compressors, and generators based on

11544-527: Was developed by the same international team responsible for the Ecotec , including the Opel engineers responsible for the 54° V6 , with involvement with design and development engineering from Ricardo plc . GM's Australian auto division Holden produced a HFV6 engine under the name " Alloytec ." The HFV6 was designed, tested, and produced in a joint program by Holden and Cadillac . A majority of designs into

11655-423: Was entrusted with doing the final design. The original badge was round, of enamelled brass , measuring 65 mm (2.6 in) in diameter, and carried already all the present day accoutrements: the red cross on a white field of Milan on the left, a green biscione on a light blue field on the right, all surrounded by a blue ring inscribed with the words "ALFA" at the top and "MILANO" at the bottom. In honour of

11766-512: Was imported to the United States by Max Hoffman from the mid-1950s. The Giulietta Spider was developed on the request of Max Hoffman, who proposed an open top version of the Giulietta. In 1961 Alfa Romeo started exporting cars to the United States through its own dealer network. In 1995, Alfa Romeo ceased exporting cars to the United States, the last model sold in that market being the 164 sedan. On 5 May 2006, Alfa Romeo made its return to

11877-495: Was mated to GM's six-speed 6L45 automatic transmission and, over the combined ADR 81/02 test cycle, the Commodore Omega achieved fuel consumption of 11.8 L/100 km (24 mpg ‑imp ; 19.9 mpg ‑US ) – an improvement of 1.6 L/100 km compared to its dual-fuel LW2 predecessor. Furthermore, the LWR engine exceeded Euro 6 emissions standards . Applications: The 3.6 L (3,564 cc) LCS

11988-453: 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

12099-461: Was readying its first model, the 24 HP . The board asked chief engineer Giuseppe Merosi to devise a badge for the radiator shell of the new car; Merosi turned to his collaborators. One of them, Cattaneo, was inspired by the coat of arms he had seen on the gates of Castello Sforzesco to include the biscione in the logo. Merosi liked the idea, and together with Cattaneo came up with a sketch, then approved by managing director Ugo Stella; Cattaneo

12210-420: Was the 24 HP , designed by Giuseppe Merosi , which became commercially successful and participated in the 1911 Targa Florio endurance race. In August 1915, ALFA was acquired by Neapolitan entrepreneur and engineer Nicola Romeo , who vastly expanded the company's portfolio to include heavy machinery and aircraft engines. In 1920, the company's name was changed to Alfa Romeo , with the Torpedo 20–30 HP being

12321-473: 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
