Product Characteristics
Basis Information
Compression ring: Located in the groove at the top of the piston, it mainly serves as a seal and conducts heat.
Oil control ring: located in the groove at the bottom of the piston, mainly used to control the supply and recovery of lubricating oil, as well as prevent gas from entering the piston suspension area.
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 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.
