Abstract

Systems and apparatuses include a lubrication system having an engine piston defining a gudgeon pin aperture, a piston pooling cavity extending radially outward from the gudgeon pin aperture, a piston cooling gallery, and a piston lubrication passage. The piston lubrication passage is in fluid communication with the piston cooling gallery and the piston pooling cavity. The piston further includes a pin journal received in the gudgeon pin aperture of the engine piston and defining a journal aperture in fluid communication with the piston pooling cavity and a journal pooling cavity in fluid communication with the journal aperture. A gudgeon pin is received within the gudgeon pin aperture adjacent the pin journal, which provides fluid communication between the journal pooling cavity and the gudgeon pin.
