Abstract:
A piston for an internal combustion engine is provided. The piston includes a body having a cylindrical outer surface with a ring belt region including an annular uppermost ring groove and a lower ring groove extending into the outer surface. A top land extends from the uppermost ring groove to an upper combustion surface. The body has a pair of pin bosses with pin bores aligned with one another along a pin bore axis. A first piston ring is disposed in the uppermost ring groove and a second piston ring is disposed in the lower ring groove. The body has an annular sealed cooling gallery with a cooling medium contained therein. The sealed cooling gallery is configured in substantial radial alignment between the first and second piston rings to provide optimal cooling to the ring belt region, top land and upper combustion surface.
