    • A control device of a high-pressure fuel pump of an internal combustion engine capable of improving stability in controlling the drive of the high-pressure fuel pump by limiting the end timing of a drive signal of the high-pressure fuel pump and driving an actuator in a control effective range of the high-pressure fuel pump. The control device of the high-pressure fuel pump of the internal combustion engine has a fuel injection valve provided on a cylinder and the high-pressure fuel pump for pumping fuel to the fuel injection valve, wherein the high-pressure fuel pump comprises a pressure chamber, a plunger for pressurizing the fuel in the pressure chamber, a fuel valve provided in the pressure chamber, and the actuator for operating the fuel valve. The 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 means for calculating the drive signal has means for limiting the end timing of the drive signal of the actuator to a predetermined phase and/or means for limiting the output timing of the drive signal of the actuator to be within a predetermined phase range.
    • 一种内燃机的高压燃料泵的控制装置,其能够通过限制高压燃料泵的驱动信号的结束定时来提高控制高压燃料泵的驱动的稳定性,并驱动致动器 在高压燃油泵的控制有效范围内。 内燃机的高压燃料泵的控制装置具有设置在气缸上的燃料喷射阀和用于将燃料泵送到燃料喷射阀的高压燃料泵,其中高压燃料泵包括压力 用于对压力室中的燃料加压的柱塞,设置在压力室中的燃料阀和用于操作燃料阀的致动器。 控制装置具有用于计算致动器的驱动信号的装置,以实现高压燃料泵的可变排放。 用于计算驱动信号的装置具有用于将致动器的驱动信号的结束定时限制到预定相位的装置和/或用于将致动器的驱动信号的输出定时限制在预定相位范围内的装置。
