High Hardness Construction Machinery Parts Engine Piston 4D76 For Yanmar 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.

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.

Piston type and surface treatment : Alfin Reinforcement

Created for operation in high temperature environment like turbo engines.

Moly Skirt : Help produce less frictional heat and engine noise.

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

FAQ

A: We can see from the pictures why the color of our products is darker than ordinary affiliates?

B: That ’s because our pistons are high-silicon and high-nickel, so the color will be darker.

A: What are the benefits of high silicon and high nickel?

B: We can refer to their performance, we can know that high silicon and high nickel products have better lubricity and higher quality, so their service life will be longer.

A: In addition to this advantage, does your product have any other highlights?

B: There are also more cooling pipes inside our pistons to facilitate better heat dissipation and make the product last longer.

A: I want to know how your after sales service

B: I forgot to tell you that our after-sales service is perfect, and we will have someone to deal with problems encountered by customers to ensure you have the best shopping experience.
