Patent ID: 7591239

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; and a high-pressure fuel pump for feeding the fuel under pressure to said common rail; wherein said high-pressure fuel pump comprises: a pressurization chamber; a plunger for pressurizing fuel in said pressurization chamber; a fuel passage valve disposed in said pressurization chamber; and an actuator for actuating said fuel passage valve; wherein said control device includes control means for executing output control of a drive signal for said actuator to vary a discharge rate of said high-pressure fuel pump; and wherein said control means starts outputting 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, when a crank angle signal has been recognized in excess of at least two times from the operation start.
