摘要： A high-pressure fuel pump accelerates a rise in fuel pressure from engine start-up to shorten an engine start-up time, reduce an exhaust gas substance and improve or increase an engine output. The high-pressure fuel pump is part of a control device which controls an in-cylinder injection engine having a fuel injection valve, a high-pressure fuel pump, and a crank angle sensor. The high-pressure fuel pump is provided with a plunger for pressurizing the fuel placed in the high-pressure fuel pump, a pump drive cam, and a cam angle sensor. A drive signal setting device outputs drive signals to the high-pressure fuel pump at least two or more times from the time of crank angle sensor signal detection to the determination time of the crank and cam angle sensor phases.

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.
