Abstract

A two-piece piston is composed of independent head (1) and skirt (2) portions, and skirt portion (2) being connected by means of a wrist pin (9) to a pair of pin bosses (7) on the lower end of support members (6) depending from the head portion (1). The head (1) is provided with an annular closed cooling chamber (5) located between ring belt (3) and the combustion bowl (4). <IMAGE>
