ABSTRACT:
A speed governor for fuel injection pumps of internal combustion engines has an electric control motor driven via an electronic control unit for actuating a quantity control member of the injection pump. A travel limitating element of the quantity control member is provided in order to determine the maximum injection quantity. The travel limitating element is adjustable independently of the electronic control unit between a position for the starting quantity and a position for the full-load quantity in accordance with engine characteristics. While the operating rpm performance graph is controlled by the electrical portion of the speed governor, the maximum rpm is determined by hydraulic-mechanical means.
