The fuel injector injects the fuel such that it builds a homogenous mixture with the added air.
Otto engines require an ignition spark in order to burn the air-fuel mixture in the combustion chamber.
By measuring the oxygen content of the exhaust gas, the lambda sensor supplies the necessary information for optimal air/fuel mixture to the engine control unit.
The LEGV meters gas into the intake manifold on the engine with extreme precision and ensures that the air and gas are mixed extremely well.
The air supply for the motor is just as important for the combustion of the air-fuel mixture as the fuel itself.
With high pressure, the unit pump ensures excellent mixture preparation and combustion of fuel with specific high performance.
The wideband lambda sensor supplies current measured data from the exhaust tract.
The electronic control adjusts the optimal mixing ratio between air and fuel as well as the optimal time of injection.
The high-pressure injector provides the interface between the fuel rail and the combustion chamber.
With gasoline direct injection, the high-pressure circuit is fed by the high-pressure pump (HDP).
