Abstract

A piston includes an upper crown portion and a lower crown portion with a pair of pin bosses spaced for receipt of a connecting rod. The pin bosses have pin bores aligned with one another along a pin bore axis. The upper crown portion and the lower crown portion form an outer oil gallery and a central oil gallery. The central oil gallery is formed in part by a floor extending radially inwardly from the outer oil gallery to a plateau. To facilitate cooling the central gallery, the plateau has a through opening and the floor has at least one trough depending axially therein. At least one oil flow passage extends in fluid communication between the outer oil gallery and the central oil gallery, wherein at least one oil flow passage is axially aligned with the at least one trough to provide a direct flow of oil to the trough.
