Title: Apparatus for treating the crankcase vapor emissions of internal combustion engines

Abstract

Apparatus for treating crankcase vapor emissions of internal combustion engines, particularly automotive engines, interposed between the engine crankcase, ventilation port and the air-fuel intake manifold. The apparatus, including a separator-collector housing with header-cover mounted thereon, is adapted to receive the crankcase emissions (including engine blow-by gases) through the header-cover and an elongated inlet conduit depending downwardly therefrom and to direct such emissions into a lower sludge collection chamber of the housing. A filter assembly is carried by the inlet conduit and spans the separator-collector housing intermediate the bottom of the housing and the header-cover thereby defining in the lower portion of the housing the sludge collection chamber and defining in the upper portion of the housing a recycle vapor chamber. Crankcase vapor emissions entering the apparatus through the header-cover and inlet conduit when discharged into the sludge collection chamber expand therein whereby heavy impurities and components drop out and collect in a pool at the bottom of the housing. The remainder of the emission mixture (including combustible components) is intercepted and strained by the filter assembly during its passage upwardly into the upper recycle vapor chamber of the housing whereby lighter impurities are filtered out of the mixture yielding amore » purified emission mixture in such upper chamber. The purified emission mixture is passed through an outlet conduit in the header-cover of the apparatus to the air-fuel intake manifold wherein it supplements the engine's fresh supply of air and fuel thereby increasing the efficiency of the engine without adding contaminants to the engine's exhaust gases.« less
