摘要： 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.

摘要： An internal combustion engine and piston therefor is provided. The piston has a body including an upper combustion wall, a cylindrical outer wall including a ring belt region depending from the upper combustion wall, and a pair of pin bosses having axially aligned pin bores. The piston has a first cooling gallery in radial alignment with the ring belt region with a cooling medium contained therein. An insert member is fixed to the body in axially spaced relation beneath a lower wall of the first cooling gallery. The insert member bounds a second cooling gallery beneath the lower wall of the first cooling gallery. The insert member has an inlet opening configured to allow oil to flow into the second cooling gallery against the lower wall of the first cooling gallery and a separate outlet opening configured to allow the oil to flow outwardly from the second cooling gallery.

摘要： A piston, piston ring and method of construction thereof is provided. The piston ring is L-shaped, having a first portion configured to extend upwardly from a ring groove of a piston along a top land of the piston and a second portion configured for receipt in the ring groove. The first and second portions of the ring have an enclosed hollow cooling chamber with a cooling medium disposed therein such that the cooling medium is free to flow internally to the piston ring groove and upwardly from the piston ring groove along the top land.

摘要： A piston for an internal combustion engine has a body including an upper combustion wall having an upper combustion surface; cylindrical outer wall with a ring belt region adjacent the upper combustion surface, and a closed annular cooling gallery located in radial alignment with the ring belt region. A cooling medium is contained in the cooling gallery. The cooling gallery has an inner surface including a radially outermost portion extending along the ring belt region. The outermost portion converges from the upper combustion wall toward a longitudinal central axis. During reciprocating motion of the piston, the cooling medium flows and remains in contact with the cooling gallery walls, thereby maximizing the capacity for heat to be transferred from the upper combustion wall to the contained cooling medium and from the cooling medium to the piston body, ring belt region and ultimately to the engine cooling system.
