ABSTRACT:
In a light alloy piston each of the load-carrying skirt surfaces is divided into a plurality of load-carrying skirt surface portions. In order to ensure that the upper portion of the piston skirt will carry load on a large area even when the engine is warming up, a plurality of depressions extending in the peripheral direction of the piston skirt are formed in the latter between its clearance-defining top and bottom ends.
