Abstract (en)
A unit injector system includes a rotary cam (22A) for imparting inward movement to a plunger (19) to displace fuel from a pumping chamber to a fuel injection nozzle (12). A spill valve (29) is utilised to control the amount of fuel supplied. The leading flank of the cam has a first portion (B1) which after initial inward movement of the plunger effects inward movement of the plunger at a substantially constant rate, a second portion (B2) during which the rate of movement is increased and a third portion (B3) during which the rate of movement of the plunger decreases until the crest of the cam is reached.
