    • The present invention relates to a control apparatus 700 for controlling a high-pressure fuel supply pump 100, a computer program product comprising computer program code means configured to adapt a control apparatus 700 for controlling a high-pressure fuel supply pump 100, and a method for controlling a high-pressure fuel supply pump 100 configured to supply pressurized fuel to an internal combustion engine. The high-pressure fuel supply pump 100 comprises a normally-closed type solenoid actuated intake valve 110 configured to be opened or kept open by magnetic force. A control current IC of the solenoid actuated intake valve 110 is controlled for opening the solenoid actuated intake valve 110 by applying a control voltage VC to the solenoid actuated intake valve 110. Controlling a control current IC of the solenoid actuated intake valve 110 comprises increasing the control current IC to a first control current value IC1 for energizing the solenoid actuated intake valve 110. Controlling a control current IC of the solenoid actuated intake valve 110 for opening the solenoid actuated intake valve 110 according to the present invention further comprises reducing the control current IC from the first control current value IC1 to a second control current value IC2 being smaller than the first control current value IC1.
    • 本发明涉及一种用于控制高压燃料供给泵100的控制装置700,包括计算机程序代码装置的计算机程序产品,该计算机程序代码装置被配置为使用于控制高压燃料供应泵100的控制装置700,以及一种方法 用于控制构造成向内燃机供给加压燃料的高压燃料供给泵100。 高压燃料供给泵100包括构造成通过磁力打开或保持打开的常闭型电磁致动进气阀110。 控制电磁致动进气门110的控制电流IC通过向电磁致动的进气门110施加控制电压VC来打开电磁致动的进气门110.控制电磁致动进气门110的控制电流IC包括增加 将电流IC控制到第一控制电流值IC1,以激励电磁致动的进气门110.根据本发明的控制用于打开电磁致动的进气门110的电磁致动进气门110的控制电流IC还包括减小控制电流 IC从第一控制电流值IC1到第二控制电流值IC2小于第一控制电流值IC1。
