摘要： A high-pressure pump includes a plunger and a control valve. An ECU adjusts a fuel discharge amount of the high-pressure pump by switching a valve opening and a valve closing of the control valve by the energization control of a coil. The ECU detects movement of the valve body with respect to a drive command of the valve opening or the valve closing of the control valve and executes an actuation determination of the high-pressure pump on the basis of a detection result. The ECU executes sound reduction control that reduces actuation sound of the high-pressure pump by controlling supply power supplied to the electromagnetic section on the basis of a determination result of the actuation determination in previous energization by the actuation determination section.

摘要： A high-pressure pump has an elastic member arranged in a damper chamber between a first diaphragm and a second diaphragm. The elastic member is always in contact with both diaphragms while the high-pressure pump is operated. When the diaphragms are further vibrated due to a resonance under a situation where a frequency of the pressure pulsation of low-pressure fuel is in agreement with the characteristic frequency of the diaphragms, the elastic member restricts the deformation of the diaphragms. Therefore, the resonance of the first diaphragm and the second diaphragm can be restricted.
