1.Force:

The force acting on the piston ring is the gas pressure,the ring's own elastic force,the inertial force of the ring reciprocating motion,the friction between the ring and the cylinder and the ring groove,as shown in the figure.Due to these forces,the ring will produce basic motions such as axial motion,radial motion,and rotary motion.In addition,due to its motion characteristics,the piston ring is accompanied by irregular movement,and inevitably,floating and axial vibrations caused by axial irregular motion,radial irregular motion and vibration,twisting motion,and the like are inevitable.These irregular movements often prevent the piston ring from functioning.When designing the piston ring, it is necessary to give full play to the favorable movement and control the unfavorable side.

2.Thermal conductivity:

The high heat generated by the combustion is transmitted to the cylinder wall through the piston ring,so that it can function as a cooling piston.The heat radiated from the piston ring to the cylinder wall can generally reach 30-40% of the heat on the top of the piston.

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.
