Technical Description

The set typically includes 5 rings that perform three primary functions:

1. Compression Sealing: The top rings prevent the air-fuel mixture and exhaust gases from leaking into the crankcase, ensuring maximum power.

2. Heat Transfer: They help transfer heat from the hot piston to the cooled cylinder wall.

3. Oil Control: The scraper rings (bottom of the set) wipe excess oil from the cylinder walls to prevent it from burning in the combustion chamber, which reduces “blue smoke” and carbon buildup.
