摘要： A high-pressure fuel pump of an internal combustion engine has a fuel injection valve provided on a cylinder. The high-pressure fuel pump is for pumping fuel to the fuel injection valve, and has a pressure chamber, a plunger for pressurizing the fuel in the pressure chamber, a fuel valve provided in the pressure chamber, and an actuator for operating the fuel valve. A control device has means for calculating the drive signal of the actuator so as to realize the variable discharge of the high-pressure fuel pump. The end timing of the drive signal is limited or restricted so that an attraction force of a solenoid coil is not maintained at the bottom dead center of the plunger in case that the required discharge to the fuel pump is less than the total discharge.
