OPERATION
The accelerator pedal position is converted into an
electrical voltage signal and sent to the injection
control unit by the potentiometer connected to the
pedal.
The accelerator pedal position signal is processed
together with the information relating to the engine
rpm to obtain the injection times and the pressure
