The fit clearance between the liner, piston and piston ring can meet the installation requirements of the main engine factory, which greatly increases the operational life of the engine.

Piston top wall using heat flow type, that is, from the top to the ring piston area wall transition arc radius is bigger, some still increase support jin (typically 4), the purpose is to make the piston at the top of the heat can be more smoothly to ring and pin (support and strengthen the stiffness and strength of the important role of piston), thereby reducing the heat of the first ring and ring groove, improve the reliability of piston group of key parts.

Piston pin seat

The pin seat is strengthened and the diameter of the piston pin is enlarged appropriately. At present, the most stressed part of the piston is the pin seat, and the fatigue crack often appears at the top of the pin hole and extends along the longitudinal plane of the piston pin seat. A great arc transition is adopted in this area to reduce stress concentration and increase stress area. In the reinforced model, the piston pin seat is usually directly connected with the top of the piston by four ribs, so as to directly transfer part of the load and reduce the load of the above dangerous parts.
