Machinery Excavator Spare Parts Engine Piston 6D31 For Komatsu Motor


High Quality Machinery Parts Engine Piston 6D31 For Komatsu Motor


The piston profile evolved from the original multi-section regular cylinder to the present circular multi-section regular cone and gradual elliptic cone, and the skirt gradual barrel elliptic cone.


The skirt shape is generally barrel - oval. The axis of the barrel coincides with the axis of the piston. The piston section perpendicular to the axis is elliptic and the short axis is along the direction of the piston pin. Some piston skirt made of multi - stage continuous elliptic cone, multi - stage continuous special circle. The advantages of barrel skirt are uniform machine oil, tensile cylinder, anti - channeling oil, oil film bearing capacity, reduce friction work and friction loss.


However, determining the best profile is an extremely complicated process that requires repeated experiments and often takes a long time. The traditional method is to analyze the temperature field and stiffness of the piston, use the finite element method and draw a piston profile based on experience, then load the obtained test samples into the engine for piston wear test, and observe the wear marks on the piston and cylinder liner. After successive approximation, the best piston profile can be determined. But due to the movement of the piston, the thermal deformation caused by different kinds of relevant factors, the piston is likely to be composed of cylinder head bolt tightening torque, the uneven cooling and the cylinder wall temperature distribution of the influence of the deformation of the cylinder wall, as well as each cylinder combustion uneven, and the characteristics of piston itself (such as stiffness, the expansion of the automatic control piston thermal expansion rate varies with the piston section) is the determination of type surface increased the difficulty.

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 .



Reduce tge fructuib from with the cylinder liner . And to protect the piston from corrosion .



The nitriding products have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance .
