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.

Five, 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.

Piston pin diameter has a slightly enlarged trend, the purpose is to increase the pin and pin seat pressure area. The larger the cylinder diameter, the higher the engine strengthening degree, the larger the ratio of piston pin diameter to cylinder diameter.

Product Description
 

Piston type & surface treatment

Alfin Reinforcement

Piston with alfin reinforcement are resistant to compression ring groove wear . the alfin reinforcement also act as a heat barrier minimizing heat conduction from piston skirt area. Such pistons can thus withstand the demand for higher load and highet performance engine .

Cooling Gallery

Created for operation in high temperature environment like turbo engines. Through oil circulation in the gallery, pistons are intensively cooled in the piston crown and ring belt area .

Anodized Crown

Anodization of piston crown creates a hard crown surface thus providing pistons with extra protection against crown piting and wear .

Tin Coating

Tin coated surface provides extra lubrication and smoother running of cylinder components resulting in longer engine lifetime .

Moly Skirt

Help produce less frictional heat and engine noise. The extra lubricative effect also minimize cylinder bore wear and prevent piston scuffing .

Phosphating

Reduce tge fructuib from with the cylinder liner . And to protect the piston from corrosion .

Nitriding

The nitriding products have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance .
