Anti-expansion piston
The different working temperature of piston and the different
expansion characteristics of aluminum alloy piston and cast iron
cylinder liner make it difficult to control the gap between piston
skirt and cylinder liner. The most efficient skirt shape cannot
overcome the differential expansion rate between piston and
cylinder.
In addition, the minimum clearance determined under the maximum
load of the engine will also cause too large clearance under
partial load, resulting in knock noise and increased engine fuel
consumption. In order to control the cylinder piston skirt
clearance, make it neither too small bite caused cylinder cylinder,
and not too big to cause noise and vibration, the piston skirt and
pin buried cast symmetry between a pair of steel sheet, and will be
appropriately extended around the periphery of the skirt of the
steel, together with the surrounding material of the steel
bimetallic strip, heat expansion shrinkage along the axis of the
piston pin in the vertical direction.
This piston in the ring groove and the skirt of the itd does not
open heat insulation groove, heat flow can be smoothly transferred
to the skirt, so the first ring groove area of the temperature than
the slotted piston, the strength is higher. Aluminum piston is
widely used to control thermal expansion by means of steel strip or
steel ring.
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
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 about 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..
