Abstract
Systems and methods are provided for cooling a piston arranged within a cylinder of an engine. Oil received from a connecting rod bearing and crank journal interface may be continuously transferred via an internal conduit in a connecting rod coupled to the piston wherein the internal conduit is formed within a hollow flange of the connecting rod. The oil may then be sprayed in a continuous manner via an external nozzle to an underside of the piston, enabling continuous piston cooling as the piston travels from a top-dead-center (TDC) position to a bottom-dead-center position (BDC) and back.
