Construction Machinery Parts Engine Piston DE12 For Doosan Daewoo

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.

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 .
