ABSTRACT:
A compensator is described for use on those manifold fuel injectors for gasoline engines which utilize a gas pressure cycler to vary the instantaneous rate of liquid fuel injection in proportion to the instantaneous rate of engine intake air flow into each engine cylinder during each intake stroke. The compensator adjusts liquid fuel injection pressure by bleeding adjustable air quantities out of the gas pressure cycler during pressure rise, and then subsequently returning these bleed masses into the gas pressure cycler during pressure decrease. A compensator of this invention is of relatively simple mechanical design, and uses a moderately complex electronic controller.
