Product Characteristics
Product Usage
Before installing the piston ring, it is necessary to confirm that the specifications and model of the piston ring match the engine requirements. Clean the piston and cylinder walls to ensure a smooth and clean surface, and remove any impurities and residues.
Product Advantage
As one of the key components of the engine, the piston ring plays an important role in the performance and reliability of the engine. The piston ring has good sealing performance, which can effectively seal the gap between the piston and the cylinder wall, preventing gas leakage during the operation 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.
