ABSTRACT:
Air circulated in the interior of a gasoline engine becomes contaminated therein with gasoline and oil vapors trapped in the crankcase. This contaminated air is then fed, by means of intake manifold vacuum, to the cylinder for combustion. By passing the contaminated air through a filtering means prior to combustion, the oil vapors are removed, providing longer spark plug life and improved engine performance and reduced oil and grease deposits in the intake manifold. A drain in the filter returns the oil collected to the crankcase for reuse.
