ABSTRACT:
A two cycle engine comprises an engine casing that defines a hollow piston cavity, a first gas passageway and a second gas passageway. The hollow piston cavity is separated from the first gas passageway by a valve seat. A piston is positioned in the hollow piston cavity and is moveable between a top position in which the second gas passageway is blocked to the hollow piston cavity, and a bottom position in which the second gas passageway is open to the hollow piston cavity. A gas valve member is positioned adjacent the valve seat and is moveable between an open position and a closed position relative to the valve seat. The gas valve member defines a nozzle outlet that opens directly into the hollow piston cavity. A needle valve member is positioned in the gas valve member and is moveable between an inject position in which the nozzle outlet is open, and a blocked position in which the nozzle outlet is blocked.
