ABSTRACT:
A multi-plunger fuel injection pump consisting of a number of reciprocable fuel pumping plungers to which is distributed fuel by a fuel distributor plunger, all of the plungers being actuated by a common camshaft, the number of distributor plungers being less than that of the pumping plungers and determined as a function of the operating range of the pump, the fuel flow to and from the individual pumping plungers being controlled by a solenoid operated spill control valve that is selectively operable to determine both the timing and duration of fuel injection.
