Construction Machinery Parts Engine Piston D2366P For Doosan Daewoo

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.

The piston skirt should not only bear the lateral thrust of the connecting rod, but also ensure the good guidance of the piston, so there should be sufficient pressure area to form a sufficient thickness of the lubricating oil film. Neither because the gap is too large and cylinder knocking, resulting in noise and accelerated wear and also because the gap is too small and cylinder pulling. The tendency is to use thin - walled reinforcement, both to reduce weight and ensure sufficient stiffness to prevent deformation.

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 .
