Top of piston

The thickness of the piston generally tends to decrease. It is mainly restricted by the two contradictory factors of the combustion pressure and the reduction of the temperature gradient. The thickness is too thin, the ability to bear mechanical load is poor, will cause mechanical deformation; If the thickness is too thick, the temperature gradient is too large, causing too much thermal stress and thermal deformation. Therefore, the piston head thickness varies with the maximum combustion pressure of the engine, the cylinder diameter, whether there is oil cooling, and the combustion chamber form.

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.

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: After your explanation, I have all moved. The products of your OKJ look very good.
B: Well, you can try to use our products, you must believe in your own vision and believe in us.

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.
