Abstract
In a cast light-alloy piston having a skirt which is recessed adjacent to the piston pin bosses, the two sides of the skirt are unsymmetrical with respect to the piston pin bosses. For an improved adaptation to the different conditions of operation of the engine, the skirt is connected to the piston pin bosses on one side by supporting ribs which extend at an angle of 30 to 60 degrees to the piston pin axis, and on the other side by supporting ribs extending at an angle of 90.degree. to the piston pin axis.
