Articulated Piston

 Articulated Piston

Two pieces constructions of pistons (articulated pistons) with forged chrome moly steel crown coupled with aluminium alloy skirt held together by a piston pin where the guidance and sealing function are separated from one another. Because of this design, the skirt is better shielded from hot piston crown and ring zone and can, therefore, be installed with smaller clearances than the one-piece piston, which has a positive effect on quiet running.
