Product Characteristics
Basis Information
The material selection of piston rings directly affects their performance and lifespan. Common piston ring materials include:
Cast iron: It has good wear resistance and thermal conductivity, and is suitable for most internal combustion engine applications.
Steel: has high strength and wear resistance, suitable for high-performance or high pressure applications.
Ladle aluminum: Combining the lightness of aluminum with the strength of steel, it has excellent wear resistance and thermal conductivity.
Product Principle
The piston rings also help reduce friction between the piston and the cylinder wall. A thin and uniform lubricating film is formed between the piston and the cylinder wall, reducing friction and improving the efficiency and lifespan of the internal combustion engine.
The piston ring can balance the temperature of the piston surface, reduce thermal stress and heat loss. Guide lubricating oil and coolant to the friction surface by setting corresponding grooves and gaps.
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.
