Abstract
Two embodiments of fuel/air injectors for an internal combustion engine wherein the main air delivery valve is actuated by a solenoid having a winding and wherein the solenoid winding is cooled by fuel in a jacket surrounding it which fuel is also delivered to the fuel injector. In one embodiment, the fuel injector solenoid and air control valve are all coaxial and in the other embodiment the fuel injector injects perpendicularly to the delivery valve and the solenoid.
Claims13
A fuel/air injector unit for injecting fuel and air under pressure into an internal combustion engine comprising a fuel injector for injecting fuel, an air delivery valve for controlling the delivery of air, said air delivery valve including a solenoid for operating said air delivery valve, said solenoid having a winding, cooling jacket in proximity to said winding, and means for circulating fuel through said cooling jacket.
A fuel/air injector unit for injecting fuel and air under pressure into an internal combustion engine comprising a housing having a discharge nozzle portion containing a chamber and a discharge port, a control valve slid ably supported within said chamber and having a head portion controlling the opening and closing of said port, a solenoid associated with said control valve for opening and closing said control valve and a fuel injector for delivering fuel to said chamber, said valve, said solenoid and said fuel injector all being coaxially disposed relative to each other in the housing.
