ABSTRACT:
A reciprocating engine including a block having at least one cylinder therein, a piston reciprocally received in the cylinder and having a crown, a depending skirt and a ring-receiving groove on the skirt near the crown. The piston has a central cavity terminating near the crown and a coolant-receiving passage in heat exchange relationship to the groove. A nozzle is stationarily mounted on the engine and has first and second jets, the first jet directing coolant to the cavity and the second jet directing coolant to the coolant-receiving passage, both for all operating positions of the piston within the cylinder. A filtered oil supply for the nozzle is provided.
