Abstract
A crankcase fluid processing system for a reciprocating automotive internal combustion engine includes a fluid collector pan for closing the lower ends of the cylinder block into separate bays and an evacuation valve for each of the bays, with the valves serving to allow fluid in the collector compartments to be expelled whenever the pistons in the bay move from top dead center to bottom dead center. As a result, the power output and fuel economy of the engine may be improved.
