ABSTRACT:
A rotary fuel injection pump with a rotor having pumping plungers reciprocated for supplying high pressure charges of fuel for fuel injection and a spill control mechanism having one or two rotary spill valves mounted on the rotor and rotated in unison with the rotor and in synchronism with the reciprocable movement of the pumping plungers for spill control of the high pressure charges of fuel. The spill timing is adjustable by the spill control mechanism at the beginning and/or end of the fuel injection event.
