Abstract
A fuel injection pump of the rotary distributor type having opposed fuel pumping pistons housed within a rotor and actuated by an internal ring cam. Fuel distribution, metering and timing control are effected through ports and slots associated with the rotor, the pump housing and a spill sleeve. The angular position of the cam is varied automatically in accordance with changes in engine speed as are the relative positions of certain ones of said ports and slots to provide an automatic advance of the fuel injection timing. The pump is particularly suited for electronic governing, electronic timing control and electronic control of rate of injection.
