ABSTRACT:
An internal combustion ventilation apparatus and method for reducing the moisture content of an internal combustion engine at rest in order to prevent or minimize corrosive activity in the engine. The apparatus includes the oil filler tube and the engine breather pipe of the engine to be ventilated, as well as a blower. The blower is connected to either the oil filler tube or the engine breather pipe and directed so that air is brought into the engine breather pipe for circulation through the engine cavities, then to be exhausted through the oil filler tube. The dryer outside air displaces moisture laden air in the engine cavities. In one embodiment of the invention an engine preheater is installed on the engine for the purpose of adding heat to the idle engine and increasing the moisture holding capacity of the air being moved through the engine.
