ABSTRACT:
A fuel injection system for externally ignited engines employing continuous manifold injection includes a fuel metering valve assembly. The control slide of this valve assembly is actuated by the air-flow through the induction manifold and controls the size of fuel flow apertures. A differential pressure valve normally maintains a constant pressure difference across these metering valve apertures. The magnitude of this normally constant pressure difference can be altered in response to signals obtained from or measurements performed on operational parameters of the engine; for example, the oxygen content of the engine's exhaust gases.
