Piston Rings

Key Functions: Sealing Combustion Gases: Compression rings, particularly the top ring, prevent high-pressure gases from escaping into the crankcase (known as "blow-by"), ensuring maximum power output. Oil Control: The bottom oil control ring (and sometimes the second ring) regulates the oil film on the cylinder wall, ensuring proper lubrication while preventing excess oil from entering the combustion chamber and burning. Heat Transfer: Rings transfer heat from the hot piston head to the water-cooled cylinder walls, reducing the risk of piston failure.
