High Nickel Doosan Excavator Parts Engine Piston Head Piston Skirt Doosan D1146t

Construction Machinery Parts Engine Piston D1146T For Doosan Daewoo

The whole piston can be divided into three parts: piston top, piston head and piston skirt.

The main function of the piston is to bear the combustion pressure in the cylinder and pass the force to the crankshaft through the piston pin and connecting rod. In addition, the piston, the cylinder head and the cylinder wall constitute the combustion chamber.

The piston roof is a component of the combustion chamber, so it is often made into different shapes. The piston of a gasoline engine can be either flat or concave, so that the combustion chamber is compact, the heat dissipation area is small, and the manufacturing process is simple. Crown piston is often used in two - stroke gasoline engines. The piston roof of a diesel engine is often pitted.

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 .
