What is a piston ring?

Between the piston and cylinder, the piston ring is a part that is needed for an engine to work efficiently. Piston Rings have 2 main functions.

Piston ring function 1: Heat conduction function

Function that releases heat from the piston to the cylinder

When the gas explodes, the temperature inside the piston reaches a heat of approximately 300 degrees Centigrade. If that heat remains inside the piston, the engine may be damaged, so that heat must be released from the interior. The piston ring helps to do that.

Function 2: Piston attitude support

Function that prevent the piston making strong contact with the cylinder wall

If the piston is at an angle, as it moves it makes contact with various places, and this can cause engine damage. The piston ring supports the piston so the piston can travel smoothly up and down.

Advantages

1.The surface of piston ring has oxide film, with corrosion resistance, anti-wear lubrication and good appearance.
2.Chrome plated layer, good wear resistance and storage lubricating oil
3.Nitriding treatment, with good wear resistance and corrosion resistance
4.Spring ptfe process, friction coefficient is very low, excellent lubricity.
