Īir Induction System The air induction system consists of the air cleaner, air flow meter, throttle valve, air intake chamber, intake manifold runner, and intake valve. Fuel is maintained at a constant pressure by means of a fuel pressure regulator. The pump is typically located in or near the fuel tank. Fuel is delivered from the tank to the injector by means of an electric fuel pump. Electronic Control System įuel Delivery System It consist of fuel tank, fuel pump, fuel filter, fuel delivery pipe, fuel injector, fuel pressure regulator and fuel return pipe. Types of Engine Sensors Mass airflow sensor Oxygen sensor Throttle position sensor Coolant temperature sensor Voltage sensor Manifold absolute pressure sensor Engine speed sensor Crank Position Sensor Cam Angle Sensor

These studies ultimately attributed a significant portion of air pollution to the automobile. Super session of Carburetors Throughout the 1950s and 1960s, various federal, state and local governments conducted studies into the numerous sources of air pollution. The LH-Jetronic system was also the first fully digital EFI system. In 1982, Bosch introduced a sensor that directly measures the air mass flow into the engine, on their L-Jetronic system. īosch developed an electronic fuel injection system, called D-Jetronic (D for Druck, the German word for pressure), which was first used on the VW 1600TL in 1967. Bosch developed an electronic fuel injection system, called D-Jetronic (D for Druck, the German word for pressure), which was first used on the VW 1600TL in 1967.

Chrysler offered Electrojector on specific high performance 1958 models …the 300D, the D500 Arguably the first series cars equipped with an EFI system, but the early electronic components were not equal to the rigors of underhood service and were too slow. In 1957, Chevrolet introduced a mechanical fuel injection option, made by General Motors‘. The first commercial electronic fuel injection (EFI) system was Electrojector, developed by the Bendix Corporation and was to be offered by American Motors (AMC) in 1957. First gasoline injection system was developed by Bosch and introduced in 1955 in Mercedes Benz-300 SL. The direct injection was in employed in some notable designs like Benz, BMW. Fuel injection was in widespread commercial use in diesel engines by mid 1920s. HISTORY Frederic joined Forward gas engine in 1889 and do experiments in fuel injection.
