2-1-1-10-porshen.html Piston

Pistons are made of a heat-resistant and high-heatwire aluminum alloy, the skirt of the piston is covered with graphite for friction reduction.

Fig. 2.16. Piston: 1–the piston – a side view; 2–axis shift; 3–external diameter; 4–the piston – the top view; 5–marking; 6–forward part of the engine; 7–dredging under valves

For noise reduction исползуются pistons with the displaced opening. Pistons and rods can be disconnected only a method of hot landing. For prevention of the wrong assembly of the piston marking is put on it (to). The piston is established so that the arrow of marking was turned to a forward part of the engine (fig. 2.16).

The piston of L3 engines has a pro-point under valves.
