Product Description

According to its position and function, the piston is usually composed of multiple rings. The first ring (upper oil ring): Located at the top, it is responsible for collecting the fuel injected by the fuel injectors in a direct injection internal combustion engine and guiding excess fuel back to the combustion chamber.

The second ring (power ring): Located below the first ring, it mainly seals the cylinder and prevents gas leakage, and can also guide exhaust gas to the exhaust system.

The design of piston rings is also a key technical aspect. For example, using special geometric shapes can optimize the sealing effect between the piston ring and the cylinder wall, and improve the flow characteristics of the combustion chamber. In addition, special designs such as double-layer piston ring structure and gas dynamic support ring can also be adopted to improve sealing performance and reduce friction losses


Product Process

The piston ring is one of the key components responsible for sealing and oil sealing in internal combustion engines. Its manufacturing process has undergone years of development and improvement to ensure that the piston ring has high strength, high wear resistance, and good sealing effect.

The product principles of piston rings include sealing principle, lubrication principle, guiding principle, heat dissipation principle, and the function of preventing impurities from entering. These principles together ensure the efficient operation, reliability, and durability of the engine and compressor. By optimizing the design and manufacturing process of piston rings, the performance and lifespan of products can be improved.

The piston ring also has the function of guiding the piston to move on the cylinder wall, ensuring the stability and accuracy of the piston. Through close contact with the cylinder wall, the piston ring limits the axial and radial displacement of the piston, preventing it from deviating from its normal motion trajectory.

The piston rings also perform lubrication functions. During operation, a small lubricating oil film is formed between the piston ring and the cylinder wall to reduce friction and wear. This helps to reduce energy consumption, extend piston ring life, and improve the efficiency of the engine or compressor

The piston ring is used to seal the gap between the piston and the cylinder block to prevent leakage of lubricating oil and combustion chamber gas. High quality piston rings can provide excellent sealing performance, ensuring the normal operation of the engine or compressor, and minimizing energy loss and environmental pollution

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.
