Diesel Fuel Pump For Kobelco Piston Engine For Sale

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 .

In order to reduce the intense heating of the first ring groove by the gas, the piston of the diesel engine is usually equipped with a spiral shallow groove around the fire bank to reduce the gas channeling along the gap between the piston and the cylinder liner by using the labyrinth step-down principle.

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.

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 .

FAQ

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

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

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

A: 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.

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

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

Q: I want to know how your after sales service

A: 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.

Q: Can we print our company logo on product and package?

A: Yes, but the quantity of the order is required. And we need you to offer the Trademark Authorization to us.

Q: What is your MOQ?

A: We do not have MOQ . We accept lower quantity for your trial order.

Q: Can I customized my own Brand ?

A: Yes, we can do, however you need to reach certain quantity for each item
