    • A high-pressure fuel pump control device capable of reducing current consumption, increasing pump durability, and promoting a rise of fuel pressure from startup. The high-pressure fuel pump control device comprises 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 the common rail. The high-pressure fuel pump comprises a pressurization chamber, a plunger for pressurizing the fuel in the pressurization chamber, a fuel passage valve disposed in the pressurization chamber, and an actuator for actuating the fuel passage valve. The control device includes a control unit for executing output control of a drive signal for the actuator to vary a discharge rate of the high-pressure fuel pump. The control unit starts 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 sets timing of stopping the outputting of the actuator drive signal to a point in time at which the fuel pressure in the common rail has boosted over a predetermined value per unit time.
    • 一种高压燃油泵控制装置,其能够降低电流消耗,提高泵的耐久性,并且促进起动时燃料压力的上升。 高压燃料泵控制装置包括用于将共轨中的燃料直接喷射到燃烧室中的燃料喷射阀和用于将压力下的燃料供给到共轨的高压燃料泵。 高压燃料泵包括加压室,用于加压加压室中的燃料的柱塞,设置在加压室中的燃料通道阀和用于致动燃料通道阀的致动器。 控制装置包括用于执行致动器的驱动信号的输出控制以改变高压燃料泵的排出速率的控制单元。 控制单元在从操作开始到致动器驱动信号能够以预定的曲柄角相位发生的时间点开始输出致动器驱动信号,并且设定停止输出致动器驱动信号的定时 到共轨中的燃料压力已经提高了每单位时间的预定值的时间点。
