Abstract:
A piston capable of operating at a high temperature and consequently contributing to a high in-cylinder temperature, as well as reducing engine oil temperature, when used in an internal combustion engine, is provided. The piston includes an upper portion and a lower portion welded together to present a cooling gallery therebetween. The cooling gallery extends circumferentially around a center axis of the piston and is spaced the center axis. A partition is located in the cooing gallery and extends from one inner surface to another inner surface of the cooling gallery. The partition extends circumferentially around the center axis, and divides the cooling gallery into at least a first gallery portion and a second gallery portion. The partition can be formed as one piece with the upper portion or the lower portion. Alternatively, the partition can be formed as a separate piece from the upper portion and the lower portion.

Claim (Index 14):
The piston of  claim 11 , wherein said partition is formed as one piece with said lower wall and extends upwardly from said lower wall and curves to a distal end at or adjacent said first inner surface of said upper inner rib such that said first gallery portion is located between said partition and a portion of said inner ribs and a portion of said lower wall, and\n said second gallery portion has a volume larger than a volume of said first gallery portion, said weld curls are located along said first weld joint in said first gallery portion and are physically separated from said second gallery portion by said partition, said lower portion of said body includes an oil inlet to said second gallery portion, said second gallery portion contains cooling oil, and said first gallery portion is sealed and contains air.
