ABSTRACT:
A piston assembly for an internal combustion engine includes a piston having a pair of opposed piston pin bosses. The bosses include first and second coaxial bores which define a piston pin bore. A connecting rod, having an end including a through-bore, extends into the piston and is connected to the piston by a piston pin assembly. The assembly includes a first journal end for disposition within the first coaxial bore, a second journal end disposed within the second coaxial bore and a spherical journal portion disposed intermediate of the first and said second ends. A bushing is assembled about the spherical journal portion and has a spherical inner surface corresponding to the spherical journal portion and an outer surface corresponding to and disposed in the connecting rod through-bore. The spherical journal portion rotates relative to the spherical inner surface of the bushing so as to facilitate rotational alignment of the piston in an engine cylinder bore.
