Title: (EN) Method for controlling high-pressure fuel supplying pump, and high-pressure fuel supplying pump employing same
(ZH) 高压燃料供给泵的控制方法以及使用该方法的高压燃料供给泵
Abstract: front page image
(EN) The purpose of the present invention is to provide: a method for controlling a high-pressure fuel supplying pump, which is capable of effectively reducing noise generated when an electromagnetic suction valve is opened; and a high-pressure fuel supplying pump employing the same. The method controls the high-pressure fuel supplying pump provided with: a suction valve 30 that is disposed at the suction side of a pressurizing chamber 11; a rod 35 that urges the suction valve 30 in the valve opening direction; and an anchor 36 that is drawn by a magnetic attraction force generated by energizationof a solenoid and moves the rod 35 in the valve closing direction, wherein when the anchor 36 moves in the valve opening direction, a first drive current is applied to the solenoid for a predeterminedtime period, and then, a second drive current, which is greater than the first drive current, is applied to the solenoid for a predetermined time period, whereby the abovementioned purpose can be achieved.
(ZH) 本发明的目的在于提供一种能够有效降低电磁式吸入阀的开阀时产生的噪音的高压燃料供给泵的控制方法以及使用该方法的高压燃料供给泵。所述高压燃料供给泵具备:吸入阀(30),其配置在加压室(11)的吸入侧;阀杆(35),其朝开阀方向对所述吸入阀(30)施力;以及衔铁(36),其被因螺线管通电而产生的磁吸引力吸引,使所述阀杆(35)朝闭阀方向移动;该高压燃料供给泵的控制方法可以通过如下内容来实现:在所述衔铁(36)朝开阀方向移动时,对所述螺线管流通规定时间的第1驱动电流,之后对所述螺线管流通规定时间的比所述第1驱动电流大的第2驱动电流。
