Corrosion Resistant Piston Ring for Audi Motor7A 2.3L Passat - 82.5mm Diameter, 1.5+1.75+3 Size Configuration

Located in the groove at the top of the piston, primarily serves as a seal and conducts heat efficiently.

Positioned in the groove at the bottom of the piston, designed to control lubricating oil supply and recovery while preventing gas from entering the piston suspension area.

The piston ring is a critical component in internal combustion engines, engineered to prevent gas and lubricating oil leakage from the cylinder pressure area to the opposite side of the piston ring or into the crankcase, ensuring optimal engine performance.

This component effectively balances piston surface temperature, reducing thermal stress and minimizing heat loss. Through precisely designed grooves and gaps, it guides lubricating oil and coolant to friction surfaces for enhanced durability.

Piston rings typically consist of multiple rings that connect closely on both sides. Common configurations include oil rings, oil control rings, and upper/lower spiral grooves. Each structural variation serves specific functions including cylinder sealing, heat conduction, and lubrication.
