4D84 2 Yanmar Engine Spare Parts Diesel Engine Piston Low Noise Eco Friendly

4D84 2 Yanmar Engine Spare Parts Diesel Engine Piston Low Noise Eco Friendly

High Hardness Construction Machinery Parts Engine Piston 4D84-2 For Yanmar Engine

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.

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.

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.
