Abstract: A piston constructed with a greater amount of its total weight located on one side of the longitudinal axis for the piston pin bore than on the other side. Where an offset piston pin mounting arrangement is utilized, the greater amount of the total weight of the piston is located on the same side of the longitudinal axis of the piston as the offset. The greater weight being provided, preferably, by making the thrust skirt of the piston of a greater wall thickness than the antithrust skirt. In another embodiment, the greater weight being provided by making the thrust wall of the piston pin bore of a greater thickness than the antithrust wall.
