RINGS
Explanation
in a vehicle engine there are a series of rings that are called piston rings,which helps in the regulation of the oil pressure and amount of oil consumed by the engine.The main function of the rings is Sealing the combustion chamber so that there is minimal loss of gases to the crank case. therefore Improving heat transfer from the piston to the cylinder wall thus regulating engine oil consumption by scraping oil from the cylinder walls back to the sump.
