特徴とする燃料噴射ポンプ。 A control sleeve slidably attached to the plunger is connected to the control rod, and includes a prestroke control actuator that rotationally drives the rod, and a position sensor that detects the rotation angle of the control rod. In a fuel injection pump in which the pre-stroke of the plunger is controlled by vertically moving a control sleeve, the rotation angle of the control rod is regulated by a stopper, and the lower limit of the pre-stroke control range is regulated by the stopper. , the control sleeve is provided so as to be able to regulate an upward movement position, and the upper limit of the prestroke control range is regulated at this upward movement position, and the prestroke between them is controlled based on the upper and lower limits of these control ranges. A fuel injection pump characterized by:
