piston ring details

The piston ring is designed to seal the gap between the piston and the cylinder wall. If this gap is too small, the thermal expansion of the piston may mean that the piston is stuck in the cylinder, causing serious damage to the engine. On the other hand, a large gap will lead to insufficient sealing of the piston ring to the cylinder wall, resulting in excessive air leakage (combustion gas entering the crankcase) and a decrease in cylinder pressure, thereby reducing the power output of the engine.

The piston ring is a metal split ring connected to the outer diameter of the piston of an internal combustion engine or steam engine. Most piston rings are made of cast iron or steel.

The main function of the piston ring in the engine is:

  1. Seal the combustion chamber to minimize the gas loss of the crankcase.

  2. Improve the heat transfer from the piston to the cylinder wall.

  3. Maintain the proper amount of oil between the piston and the cylinder wall

  4. Adjust engine oil consumption by scraping oil from the cylinder wall back to the oil pan.
