Abstract
A piston for an internal combustion engine is provided. The piston includes an open inner cooling area in which the undercrown surface is exposed, and an annular outer cooling gallery. The piston also includes an oil outlet scoop for local cooling of the undercrown surface of the piston. The outer cooling gallery includes an oil outlet opening, and the oil outlet scoop is beneath and vertically aligned with the oil outlet opening. The oil outlet scoop includes a concave surface facing the oil outlet opening. During operation, oil exits the oil outlet opening, and the oil outlet scoop catches the exiting oil and directs the oil to the inner cooling area and the exposed undercrown surface.
