Abstract

The amount of fuel injected by an electromagnetic injector 14 is determined volumetrically, and may be determined by the adjustable piston stop 12 of the accumulator 8. A pump (37), Fig. 3 (not shown), may deliver pedal determined fuel volumes to respective accumulators (30) with fuel pressure biased delivery pistons (32). The accumulator chamber (21), Fig. 2 (not shown), may be defined within the injector (25). <IMAGE>
