Product Characteristics
Basis Information
The piston rings are also constantly being improved and innovated to enhance the performance and efficiency of internal combustion engines. Some technical features include:
High temperature coating: To cope with high temperature environments, providing better heat resistance and lubrication performance.
Low friction coating: reduces friction loss, improves efficiency, and saves energy.
Precision machining: Through precision machining and measurement technology, the size and surface quality of piston rings are improved to achieve better sealing and durability.
Product Principle
The piston ring is usually equipped with grooves and gaps to guide the flow of lubricating oil and coolant. These grooves and gaps help to transport an appropriate amount of lubricating oil and coolant to the friction surfaces at the top and bottom of the piston, providing sufficient lubrication and cooling effects, reducing friction, heat, and wear.
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.
