ABSTRACT:
A fuel injector system permits easier control of opening and closing a spill control solenoid valve of a high pressure supply pump. An electronic control unit holds the spill control solenoid valve fully closed or opened for the entire period of each stroke, during which delivery of fuel is possible, of a pump chamber. It adjusts the number of delivery cycles according to engine load, thereby controlling the pressure of fuel in the common rail to a desired pressure level.
