ABSTRACT:
A nozzle for the air injection of fuel into the combustion chamber of a diesel engine cylinder. Included is a plunger reciprocably mounted in a nozzle body to define an air chamber for receiving compressed air from the combustion chamber during the compression stroke of the piston in the engine cylinder. Formed integral with the plunger, a needle valve defines within the nozzle body a fuel chamber for receiving fuel to be injected. A nozzle tip secured to the nozzle body founds a premixing chamber open directly to the combustion chamber and further in communication with both air chamber and fuel chamber. Thus, upon descent of the plunger at the end of the compression stroke, the fuel from the fuel chamber is intimately premixed in the premixing chamber with the compressed air from the air chamber, prior to introduction into the combustion chamber.
