Patent ID: 7325536

Claim:
A high-pressure fuel pump control device for an engine comprising: a fuel injector valve for directly injecting fuel in a common rail into a combustion chamber, a high-pressure fuel pump for feeding the fuel under pressure to said common rail, said high-pressure fuel pump comprising a pressurization chamber, a plunger for pressurizing the fuel in said pressurization chamber, a fuel passage valve disposed in said pressurization chamber, and an actuator for actuating said fuel passage valve, and a control unit for executing output control of a drive signal for said actuator to vary a discharge rate of said high-pressure fuel pump, starting outputting of the actuator drive signal during a period from operation start to a point in time at which the actuator drive signal becomes able to issue in a predetermined crank angle phase, and setting timing of stopping the outputting of the actuator drive signal based on fuel pressure in said common rail.
