Common problems with Piston Ring include:

1.Wear: Due to long-term use and friction, resulting in the surface wear of the piston ring, reducing the sealing performance.

2. Ablation: Due to the friction under high temperature and high pressure, the surface of the piston ring is ablated, affecting the sealing performance.

3. Damage: the piston ring may crack or break, resulting in reduced sealing performance.

4. Blockage: Oil stains or carbon deposits may accumulate on the piston ring, causing the piston ring to get stuck or lose elasticity.

5. Loose: the piston ring may be loose and lead to reduced sealing performance.

6. Increased fuel consumption: Piston ring problems will lead to increased fuel consumption inside the engine, affecting fuel economy

What is a piston ring?

Between the piston and cylinder, the piston ring is a part that is needed for an engine to work efficiently. Piston Rings have 2 main functions.

Piston ring function 1 :Seal for combustion gas

Function is to fully maintain in-cylinder airtightness between the piston and cylinder wall

It works hard to keep a lid on combustion gas leaking into the gap between the piston and cylinder created at the time of an explosion.
If combustion gas leaked, full power could not be realized and fuel consumption would increase, which is detrimental both economically and environmentally.

Function 2: Control lubricating oil (engine oil)

Function to constantly create the minimum required lubricating oil layer to prevent burn

Inside an engine's cylinder, the piston ring is subject to high-temperature combustion gas, and, with the piston, must travel and return many thousands of times a minute, or even more.
To ensure the piston ring and cylinder do not burn, and to prevent excess lubricating oil getting inside the combustion chamber, the cylinder wall lubricating oil layer is controlled at the minimum required.
