Piston Rings

Production with special materials, treatment with specific techniques and high precision machining, ensure high durability and high levels of functional efficiency to the piston rings. The extra treatment ensures superior sealing, contributing to the reduction of oil consumption in the engine.

The piston ring sets consist of:

• Compression ring: responsible for sealing 85% to 90% of the chamber’s combustion gases, preventing these gases from escaping to the engine’s crankcase. It also performs the exchange of heat absorbed by the piston to the cylinder wall.
• Wiper ring: helps to retain the compression and wipe the excess of lubricating oil from the cylinder wall, maintaining a thin layer to reduce the friction of the assembly. It also works by sealing 10% to 15% of the combustion gases.
• Oil ring: responsible for controlling a film of lubricating oil on the cylinder wall and discharging the excess to the crankcase. It has minimum rates of thermal transfer.
