ABSTRACT:
An improved system for ventilating and utilizing crankcase vapors in an internal combustion engine uses an air pump for feeding air to both the first and second air flow circuits of the system such that air and crankcase vapors will be withdrawn from the engine crankcase to the first circuit and directed to the engine intake system, while air will be added to the crankcase from the second circuit. The air pump is connected to and driven by the engine such that feeding of air to the first and second circuits is regulated in direct proportion to the rpm of the engine.
