Product Characteristics
Basis Information
As an important component of internal combustion engines, piston rings have a significant impact on their performance and lifespan while ensuring their normal operation. The main function of piston rings is to form a seal between the piston and cylinder wall, reduce friction losses, and guide the flow of lubricating oil and coolant.
Product Principle
The piston ring is an important component in the internal combustion engine, which can prevent gas and lubricating oil from leaking from the cylinder pressure area to the other side of the piston ring or entering the crankcase, ensuring the normal operation of the internal combustion engine.
The piston rings are located in the grooves at the top and bottom of the piston, in close contact with the cylinder wall. During the working process, the piston ring forms a closed sealing chamber between the piston and the cylinder wall through its own elasticity and shape design.
The piston ring is generally composed of several rings, closely connected on both sides. Common structures include oil rings, oil control rings, and upper and lower spiral grooves. The piston rings with different structures undertake different functions, such as sealing the cylinder, conducting heat, lubricating, etc.
