Abstract
A number of embodiments of crankcase ventilating systems for gas powered internal combustion engines employed in heat pumps. The crankcase ventilating system includes an oil vapor separator for separating and condensing oil from the crankcase ventilating gases and returning water vapor and the crankcase ventilating gases to the engine induction system for further combustion and purification. A number of various arrangements for controlling the temperature of the oil vapor separator are disclosed and an embodiment is disclosed that employs a pair of oil vapor separators acting in series.
Claims6
An internal combustion engine having a crankcase and crankcase ventilating system and contained within a housing having an air inlet and an air discharge through which cooling air is circulated, an oil vapor separator contained within said housing, conduit means for delivering gases from said crankcase ventilating system to said oil vapor separator, return conduit means for returning condensed oil from said oil vapor separator to said crankcase, ventilating discharge means for discharging ventilating gases from said oil vapor separator to said engine for combustion in a combustion chamber thereof, said oil vapor separator being positioned within the housing in such a manner that heat transferred from said engine to the interior of said housing will heat said oil vapor separator, and means for controlling the temperature within the housing to maintain sufficient heat in said oil vapor separator to vaporize water vapor for separation from lubricant and to prevent overheating of said engine.
