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.
Claims4
A crankcase fluid processing system for a four stroke cycle reciprocating automotive internal combustion engine having a plurality of pistons and a crankshaft housed within a cylinder block divided into bays defined by main bearing bulkheads, with said fluid processing system comprising:
- a fluid collector pan for sealingly closing lower ends of said bays, so as to define a separate, isolated fluid collection compartment for each bay;
- a plurality of evacuation valves, with at least one of said valves being associated with each of said fluid collection compartments, with said valves serving to allow fluid collected in said compartments to be expelled from the collection compartments in response to movement of the pistons in the direction of bottom dead center, with said evacuation valves further serving to prevent air from entering the bays when the pistons move to the top dead center position.
