Abstract:
An internal combustion engine ventilation apparatus for reducing the moisture content of air in an internal combustion engine at rest, comprising:an oil filler tube having an inside end connected to an internal combustion engine to be ventilated and open to internal cavities thereof, with the oil filler cap removed so that the outside end of the oil filler tube is open to the environment surrounding the engine;an engine breather pipe having an inside end connected to the engine and open to internal cavities thereof, the outside end of the engine breather pipe being open;at least one engine preheater installed on the engine at a location to add heat to air in the engine cavities in order to increase the moisture holding capacity of the air in the engine cavities;a blower connected to the outside end of the breather pipe directed to blow air into the breather pipe from the external environment so that air will circulate through the internal cavities of the engine and exhaust through the oil filler tube, said blower being electrically powered and connectable to an electrical source remote from the internal combustion engine.
