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for feeding air to both the first and second air flow circuits of the system such that air and crankcase vapors will be withdrawn from the engine crankcase to the first circuit and directed to the engine intake system, while air will be added to the crankcase from the second circuit.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.
Claims3
In a crankcase ventilating and vapor utilizing sytem for an internal combustion engine having a sealed crankcase and an air-fuel intake system, said system having a first air flow circuit for withdrawing crankcase vapors from said engine crankcase and directing the same into said engine intake system, a second air flow circuit for providing a flow of air into said engine crankcase, and a third air flow circuit for metering air into said engine intake system to provide compensation for the addition of said crankcase vapors into said intake system, the improvement in said crankcase ventilating and vapor utilizing system comprising:
- air pumping means connected to both said first and second circuits for feeding air to said first and second circuits such that air and crankcase vapors will be withdrawn from said crankcase to said first circuit and directed to said engine intake system, as air is added to said crankcase from said second circuit, whereby a continuous circulation of air through said crankcase and ventilation of vapors therefrom is achieved, accompanied by combustion of said vapors in said engine after introduction through its intake system.
