Abstract

A fuel injection system is proposed which serves to inject fuel into the combustion chambers of internal combustion engines. The fuel injection system includes at least one inlet and one outlet line each for the fuel, at least one pump piston to supply the fuel to an injection valve, and at least one apparatus to adjust a parameter of the injection system, such as instant of injection, or quantity of injection, or both. Furthermore, the fuel injection system includes an electro-fluidic transducer which can be controlled by an electronic control device, the electro-fluidic transducer acting to adjust the desired parameter.
