Air Assisted Fuel Injector with Timed Air Pulsing: 5,526,796

A fuel injector valve controls both the metered flow of fuel and the metered flow of air into a mixing chamber, permitting intermittent, cyclic flow of both air and fuel into the chamber. The controlled cycling of both the air and fuel flow permits optimization of fuel performance. A single action valve and a dual action valve are disclosed. The air flow and fuel flow may be independently adjusted for maximum flexibility.
