ABSTRACT:
The present invention provides an improved cooling system for a reciprocating piston engine. The engine is of the type having at least one cylinder and a piston movable between a top dead and bottom dead center. The cooling system comprises a housing or coolant jacket which encircles the outer end of the cylinder and extends towards the inner end of the cylinder. The coolant jacket, however, terminates short of the inner end of the piston when the piston is at its top dead position. A fluid passageway is formed through the housing and has both an inlet and outlet. Liquid coolant is supplied under pressure to the inlet port on the housing. The coolant flows through the lower section of the water jacket surrounding the piston area thus achieving uniform adequate cooling of both the combustion chamber and piston. In addition, an oil nozzle mounted within the engine crankcase directs a jet of oil onto the inner surface of the piston dome for further cooling of piston and subsequently supplements cooling of the cylinder barrel and head. The oil jet is the primary cooling mechanism for the section of the barrel not enclosed by the water jacket.
