A piston has a pair of diametrically opposite skirt portions with convex outer surfaces. Each skirt portion has opposite side edges extending substantially parallel to a central axis of the piston to a free end. The skirt portions each have a recessed slot extending radially into the convex outer surface to a recessed surface. The recessed surface extends fully across the convex outer surface to the side edges and separates an upper band section of the convex outer surface from a lower band section of the convex outer surface.

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.

A piston for an internal combustion engine including a piston body (). The piston body () defines a first cooling chamber () that is sealed closed and contains a first cooling medium () other than air. During operation of the piston, the first cooling medium () extracts heat from the surrounding regions of the piston body () to cool the piston body (). The piston body () also defines a second cooling chamber () adjacent to the first cooling chamber (). A cooling oil () is projected into the second cooling chamber () and against the portion of the piston body () separating the first and second cooling chambers () to extract heat from the first cooling medium (). The cooling oil () is redirected within the second cooling chamber () to extract additional heat from the first cooling medium () or directly from the piston body ().

A piston head has a top extending radially about a first axis and first and second pin bosses depending downwardly and defining first and second pin bores. A connecting rod includes a fork having first and second connecting bosses spaced apart from each other and defining first and second connecting bores. A piston skirt extends cylindrically and includes a bridge extending diametrically through the first axis defining a skirt bore for axial alignment with said pin bores and said connecting bores. The bridge is disposed between the first and second connecting bosses, which are disposed between the pin bosses. The pin bores are axially aligned with the connecting bores and with the skirt bore. A wrist pin extends within the pin bores and the connecting bores and the skirt bore along the second axis to interconnect the piston head and the connecting rod and the piston skirt.

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.

A piston assembly including a piston body pivotally connected to a connecting rod by a wrist pin. The wrist pin includes a sealed cavity therein partially filled with a heat transfer medium. The heat transfer medium may be composed of a fusible alloy. The sealed cavity may be comprised of discrete compartments. The wrist pin may be integrated with the connecting rod and share a conjoined sealed cavity therewith so that heat transfer medium can draw heat effectively away from the piston body.
