ABSTRACT:
A nozzle for injecting fuel premixed with air into the combustion chamber of a diesel engine cylinder. Included is a piston reciprocably mounted in a nozzle body to define in combination with the nozzle body an air chamber for receiving compressed air from the combustion chamber of the engine cylinder and a fuel chamber for receiving fuel from a fuel injection pump. Formed integral with the piston, a needle valve is adapted to open and close spray holes opening to the combustion chamber. Formed in the piston is a passage having a check valve mounted therein for allowing air to pass from the air chamber to the fuel chamber.
Thus, upon descent of the piston at the end of the compression stroke, the fuel is intimately premixed with the compressed air from the air chamber, prior to the introduction into the combustion chamber.
