Abstract
A compact one piece piston for use in an internal combustion engine has a compression height (“CH”) of between 55 percent and 70 percent the piston diameter (“D”) and a closed piston cooling gallery defined by a piston ring belt welded at spaced locations to a piston body and to a flange portion of the piston body. The flange portion supports a second end of the piston ring belt and resists deflection of the piston ring belt. The closed piston cooling gallery is configured to promote heat transfer and piston cooling by facilitating shaking of a cooling fluid located within the closed piston cooling gallery during reciprocal piston movement. A piston skirt extending from the flange provides additional strength and rigidity.
