ABSTRACT:
Interposed in a conduit which conducts crankcase emissions to the air-fuel intake side of an internal combustion engine is a vessel having means for separating deleterious liquid and solid components from the crankcase emissions and collecting these contaminants in the vessel. Atmospheric air is brought into collision with the emissions to enhance separation. The cleaned gaseous fraction, mixed with atmospheric air is then conducted from the vessel through a positive crankcase ventilation (PCV) valve interposed in the portion of the conduit leading from the separator-collector to the air-fuel intake side of the engine. The clean gas-air mixture joins the engine's air-fuel mixture in the combustion chamber and increases vehicle mileage.
At suitable intervals the separator-collector vessel is disconnected from the conduit and the collected contaminants are removed.
