ABSTRACT:
A two cycle crankcase compression internal combustion engine including an air/fuel injector unit for injecting fuel and air into the engine. Compressed air is delivered to the fuel/air injector unit from an air compressor and a heat exchanger is provided in this line for cooling the air. The cooling is sufficient to cause condensation of any water vapor in the air and the condensate is drained from the system after the engine is stopped through an electrically operated valve. This valve also serves to reduce the pressure of the air in the system when the engine is stopped so that fuel and air will not be discharged if the fuel/air injector unit is removed when the engine is shut down for servicing.
