ABSTRACT:
In a light alloy piston having a convex and oval external shape, the piston skirt has in the cold state a larger running clearance at its top end than at its bottom end. In order to reduce the friction loss of such piston, the piston skirt has a larger ovalness adjacent to the horizontal plane extending through the pin axis than in the remaining regions of the piston skirt.
