Abstract

An internal combustion engine piston comprising a crown portion, a skirt portion hanging therefrom, a first pin protrusion attached to the crown portion on one side of the piston, and a second pin protrusion attached to the portion ring on the opposite side of the piston, both projections presenting some titular cavities destined to receive a bolt, characterized in that reinforcing portions, each one joined and fused with the skirt portion, put one side of the piston in relation to its opposite side.
