ABSTRACT:
A liquid fuel pumping apparatus for supplying fuel to a multi-cylinder engine has a plurality of outlets for connection to the injection nozzles of the engine. The apparatus includes a spill passage and a spill control valve which is electrically controlled. The valve is closed to cause fuel from a high pressure pump to be delivered through the outlets, fuel being supplied by the high pressure pump to the outlets in turn. A pressure transducer provides signals indicative of the pressures attained in the various outlets during delivery of fuel therethrough. One of the pressure signals serves as a standard and the other signals are compared with this signal to produce correction signals which vary the time the spill valve is closed when fuel is supplied to those outlets to which the other signals pertain.
