Piston profile has great influence on engine performance and reliability, so it is an important research topic to determine piston profile when designing a new engine. The friction of piston type facing the cylinder wall, the noise caused by piston tapping, and the ring gap have important effects on the formation of hydrocarbons in the oil cooler and the air utilization and compression ratio in the diesel engine, which directly affect the engine performance. The piston profile is closely related to the increase of engine fuel consumption and channeling volume caused by cylinder drawing, abrasion and skirt deformation, which directly affects the reliability of the engine.
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.
Piston type and surface treatment : Alfin Reinforcement
Created for operation in high temperature environment like turbo engines.
Moly Skirt : Help produce less frictional heat and engine noise.
Nitriding: The nitriding products have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance .

Piston type & surface treatment
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 .
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 .
Anodization of piston crown creates a hard crown surface thus providing pistons with extra protection against crown piting and wear .
Tin coated surface provides extra lubrication and smoother running of cylinder components resulting in longer engine lifetime .
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 .
