Abstract
In a light alloy piston for internal combustion engines the mounting for the piston pin is designed for heavy loads. The piston comprises piston pin bosses which are integrated in the skirt of the piston and provided with an inelastic block support. In order to reduce the weight those end faces of the piston pin bosses which face the small end of the connecting rod are outwardly setback below those segments of the top apex portions of the bosses which include an angle of less than 180 degrees.
