Abstract
A control mechanism for a fuel injection pump comprises: an electronic governor which actuates a rack actuator by a controller for controlling a governing rack; and a cold start device which actuates an injection-quickening actuator by the controller for opening or closing a draining sub port formed in a plunger barrel so as to advance injection timing when an engine is cold. Different settings about control degree of the governing rack controlled by the controller are prepared for a case where the injection-quickening actuator is actuated to switch on the cold start device (as characteristic curve), and for a case where the injection-quickening actuator is disactuated to switch off the cold start device (as characteristic curve), respectively.
