What should be paid attention to when installing the gas ring?

[MacJameson]

Matters needing attention when installing the gas ring are: 1. The outer opening faces upward, and the inner opening faces downward; 2. The side with markings faces upward, and the side without markings faces downward; 3. Stagger the openings to avoid gas leakage. The gas ring, also known as the piston ring, is a metal ring used to fit into the piston groove. Piston rings are divided into compression rings and oil rings. The functions of the piston ring are: 1. Sealing: It refers to sealing the combustion gas, preventing the gas in the combustion chamber from leaking into the crankcase, controlling the gas leakage to a minimum, and improving thermal efficiency; 2. Regulating oil: It scrapes off excess lubricating oil from the cylinder wall while ensuring an oil film on the cylinder wall, guaranteeing normal lubrication for the cylinder, piston, and rings.
