There is a tendency to increase the height of the fire bank, especially the semi-separated combustion chamber diesel engine with the combustion chamber arranged in the piston roof. In order to prevent the top ring carbon and adhesive, and the requirements of the first ring groove temperature can not be too high, for this reason, in addition to the use of ring groove set ring, the fire bank has a long trend, and the higher the degree of reinforcement, the more obvious the trend.

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.

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 .
