A high-pressure fuel supply apparatus is provided to solve such a problem.A high-pressure fuel supply apparatus according to the present invention is configured such that if the high-pressure fuel supply apparatus or a control apparatus thereof causes malfunction to increase the pressure in the common rail, the pressure in the common rail does not exceed pressure affecting the flow characteristic and spray characteristic of the injector after recovery from the malfunctioning state.

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.
