Abstract
A cast light metal piston has a plurality of longitudinally extending reinforcing members. These reinforcing members may be disposed at predetermined positions in the piston as cast and are designed to impart a compressive stress to the material of the piston in the regions where the reinforcing members are located. Conveniently, the reinforcing members may be located adjacent the opposite sides of each of a pair of gudgeon pin holes provided in the skirt of the piston.
