Abstract
A fuel system for a diesel engine incorporating a distributor pump for controlling the operation of a plurality of fuel injectors. Each injector comprising a housing having situated therein an intensifier piston. The housing and intensifier piston cooperate to create a plurality of variable volume chambers including an upper, middle and metering chamber. The fuel injector incorporates a means entrapping a quantity of fuel during the injection mode of operation means for forming a vacuum pressure within the middle chamber to reduce the trapped fuel to its vapor pressure after the metering mode of operation has begun to ensure that the actual pressure intensification is nearly equal to the theoretical intensification ratio by minimizing unnecessary losses.
