Number of piston rings

In recent years, in order to reduce the friction work, improve the mechanical efficiency, reduce the ring height and shorten the piston compression height and total height, the number of piston rings is decreasing.

From the 30 s 5~6 ring groove development to 2~3 ring groove. It was found that more than one compression ring was not necessary, because if the upper compression ring failed, the other compression rings could not seal the gas in the combustion chamber from leaking into the crankcase, nor could they control the oil up the cylinder wall into the combustion chamber.

Therefore, instead of increasing the number of piston rings, it is better to take measures to improve the performance of piston rings, with a compression ring and two oil ring grooves to ensure the completion of sealing gas and oil control.

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
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: 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.
