The pistons are made of heat-resistant and high thermal conductivity of aluminum alloy, the piston skirt coated with graphite to reduce friction.
To reduce noise In Use pistons with an offset opening. The pistons and connecting rods can be separated interpretation by shrink fitting. To prevent incorrect assembly of the piston at a marking (?�). The piston is positioned so that the arrow marking faces the front of the engine
(Fig. 2.16).
