AN IMPROVED HEAT INSULATED PISTON ASSEMBLY AND METHOD OF ASSEMBLING Abstract of the Disclosure An improved heat insulated piston assembly for an internal combustion engine and a method of assembly. The improved piston assembly includes a piston constructed of a sleeve having an interference fit about a heat insulated core. The core has a first end positioned flush with an end of the sleeve and has a second end located within the sleeve with a concave configured cavity formed therein. Mating in the concave configured cavity of the core is a connecting rod having a spherical ball shaped end. The spherical ball shaped end is securely held in the cavity by a retaining ring which attaches to the piston sleeve. The retaining ring allows for limited movement of the spherical ball shaped end of the connecting rod in the cavity while providing a means for returning the piston to its bottom position during the intake stroke.
