Abstract
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.
