High Nickel Doosan Excavator Parts Engine Piston Head Piston Skirt
Doosan D1146 D1146 65.02501-0172
Construction Machinery Parts Engine Piston D1146 For Doosan Daewoo 65.02501-0172
Piston is made from special material for for high power EFI diesel
engine. High content of copper, silicon and nickel makes better
stability of our pistons.
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.

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 .
