Fuel injection is the introduction of fuel in an internal combustion engine, most commonly automotive engines, by the means of an injector. This article focuses on fuel injection in reciprocating piston and rotary piston engines.
A carburetor or carburettor is a device that mixes air and fuel for internal combustion engines in an appropriate air–fuel ratio for combustion. The term is sometimes colloquially shortened to carb in the UK and North America or to carby in Australia. To carburate or carburete means to mix the air and fuel or to equip with a carburetor for that purpose.
The Chevrolet Corvette, colloquially known as the 'Vette, is a two-door, two-passenger sports car manufactured and marketed by Chevrolet across more than 60 years of production and eight design generations. From 1953 to 2019, it was front-engined, and since 2020, it is mid-engined. With its generations noted sequentially from C1 to C8, the Corvette serves as Chevrolet's halo vehicle and is widely noted for its performance and distinctive plastic—either fiberglass or composite—bodywork.
The Chevrolet small-block engine is a series of V8 automobile engines used in normal production by the Chevrolet division of General Motors between 1954 and 2003, using the same basic engine block. Referred to as a "small-block" for its comparative size relative to the physically much larger Chevrolet big-block engines, The small block family spanned from 262 cu in (4.3 L) to 400 cu in (6.6 L) in displacement. Engineer Ed Cole is credited with leading the design for this engine.
The Duramax V8 engine is a General Motors Diesel V8 engine family for trucks. The 6.6-liter Duramax is produced by DMAX, a joint venture between GM and Isuzu in Moraine, Ohio. The Duramax block and heads are poured at The Defiance GM Powertrain foundry in Defiance County, Ohio. This engine was initially installed in 2001 Chevrolet and GMC trucks, and has been an option since then in pickups, vans, and medium-duty trucks. In 2006, production at Moraine was reportedly limited to approximately 200,000 engines per year. On May 9, 2007, DMAX announced the production of the 1,000,000th Duramax V-8 diesel at its Moraine facility. The 2,000,000th Duramax V8 engine rolled off the line in Moraine on March 24, 2017.
An engine control unit (ECU), also commonly called an engine control module (ECM) is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. It does this by reading values from a multitude of sensors within the engine bay, interpreting the data using multidimensional performance maps, and adjusting the engine actuators. Before ECUs, air–fuel mixture, ignition timing, and idle speed were mechanically set and dynamically controlled by mechanical and pneumatic means.
Zora Arkus-Duntov was a Belgian-born American engineer whose work on the Chevrolet Corvette earned him the nickname "Father of the Corvette." He is sometimes erroneously referred to as the inventor of the Corvette, whereas that title belongs to Harley Earl. He was also a professional racing driver, appearing at the 24 Hours of Le Mans four times and taking a class win in 1954.
General Motors introduced a line of Diesel V8 engines for their C/K pickup trucks in 1982. This engine family was produced by GM through 2000, when it was replaced by the new Duramax line. AM General's subsidiary General Engine Products (GEP) still produces a military variant of this engine for the HMMWV.
The Chevrolet Corvette (C1) is the first generation of the Corvette sports car produced by Chevrolet. It was introduced late in the 1953 model year, and produced through 1962. It is commonly referred to as the "solid-axle" generation, as the independent rear suspension did not appear until the 1963 Sting Ray. The Corvette was rushed into production for its debut model year to capitalize on the enthusiastic public reaction to the concept vehicle, but expectations for the new model were largely unfulfilled. Reviews were mixed and sales fell far short of expectations through the car's early years. The program was nearly canceled, but Chevrolet decided to make necessary improvements.
The Chevrolet Corvette (C2) is the second generation of the Chevrolet Corvette sports car, produced by the Chevrolet division of General Motors for the 1963 to 1967 model years.
The Chevrolet Corvette (C3) is a sports car that was produced from 1967 to 1982 by Chevrolet for the 1968 to 1982 model years. Engines and chassis components were mostly carried over from the previous generation, but the body and interior were new. It set new sales records with 53,807 produced for the 1979 model year. The C3 is the third generation of the Chevrolet Corvette, and marks the second time the Corvette would carry the Stingray name, though only for the 1969 - 1976 model years. This time it was a single word as opposed to Sting Ray as used for the 1963 - 1967 C2 generation. The name would then be retired until 2014 when it returned with the release of the C7.
The Chevrolet Corvette (C4) is a sports car produced by American automobile manufacturer Chevrolet from 1983 to 1996. The convertible returned, as did higher performance engines, exemplified by the 375 hp (280 kW) LT5 found in the ZR-1. In early March 1990, the ZR-1 would set a new record for the highest 24 hour-5,000 mile land-speed by going over a speed of 175 mph (282 km/h). Prices rose and sales declined, in spite of a completely new chassis, modern sleeker styling, and other improvements to the model. The last C4 was produced on June 20, 1996.
Rochester Products Division (RPD) was a division of General Motors that manufactured carburetors, and related components including emissions control devices and cruise control systems in Rochester, New York. In 1995 Rochester became part of Delphi, which in turn became a separate company four years later, and continues to manufacture fuel injection systems in Rochester, now part of General Motors Automotive Components Holdings- Rochester Operations.
The Chevrolet Engineering Research Vehicle (CERV) is a series of Chevrolet experimental cars. Chevrolet Staff engineer, designer, and race car driver Zora Arkus-Duntov started development of the CERV I in 1959, and began work on the CERV II in 1963. Chevrolet chief engineer Don Runkle and Lotus' Tony Rudd discussed creating a new show car to demonstrate their engineering expertise in 1985; It would become the CERV III. Corvette chief engineer Dave Hill unveiled the CERV IV in 1993, a test vehicle for the 1997 C5 Corvette.
The Corvette Stingray Racer is a sports racing car and concept car that debuted in 1959. The car was developed in the styling studios at General Motors (GM) at the behest of Bill Mitchell, GM Vice President of styling. The design was based on a sketch by designer Pete Brock, and was further developed by Larry Shinoda. The car strongly influenced the styling of the second generation (C2) Corvette Sting Ray.
The Chevrolet Aerovette was a concept car created by Chevrolet, beginning life as Experimental Project 882 (XP-882) in the late 1960s. It had a mid-engine configuration using a transverse mounting of its V8 engine. Zora Arkus-Duntov's engineers originally built two XP-882 prototypes during 1969, but John DeLorean, Chevrolet's general manager, canceled the program believing it to be impractical and costly. However, when Ford announced plans to sell the DeTomaso Pantera through Lincoln-Mercury dealers, DeLorean ordered that one XP-882 prototype be cleaned up for display at the 1970 New York Auto Show.
The Chevrolet Corvette SS is a sports racing car built by Chevrolet in 1957. The car raced once at the 1957 12 Hours of Sebring before Chevrolet withdrew from all racing activities.
The Chevrolet Corvette Super Sport is a show car built by the Chevrolet division of General Motors (GM). Described as a 1957 model, it was first shown in December 1956 in New York city. Only one was built.
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine. In a manifold-injected engine, the fuel is injected into the intake manifold, where it begins forming a combustible air-fuel mixture with the air. As soon as the intake valve opens, the piston starts sucking in the still forming mixture. Usually, this mixture is relatively homogeneous, and, at least in production engines for passenger cars, approximately stoichiometric; this means that there is an even distribution of fuel and air across the combustion chamber, and enough, but not more air present that what is required for the fuel's complete combustion. The injection timing and measuring of the fuel amount can be controlled either mechanically, or electronically. Since the 1970s and 1980s, manifold injection has been replacing carburettors in passenger cars. However, since the late 1990s, car manufacturers have started using petrol direct injection, which caused a decline in manifold injection installation in newly produced cars.
The Bendix Electrojector is an electronically controlled manifold injection (EFI) system developed and made by Bendix Corporation. In 1957, American Motors (AMC) offered the Electrojector as an option in some of their cars; Chrysler followed in 1957. However, it proved to be an unreliable system that was soon replaced by conventional carburettors. The Electrojector patents were then sold to German car component supplier Bosch, who developed the Electrojctor into a functioning system, the Bosch D-Jetronic, introduced in 1967.
