Abstract:
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.
