Engine Piston

The piston also features piston rings, which are circular metal bands fitted around its circumference. These rings serve multiple purposes. Firstly, they help seal the combustion chamber, preventing the escape of gases and ensuring maximum pressure is exerted on the piston. Secondly, they aid in heat transfer by scraping oil off the cylinder walls and distributing it across the piston surface. Lastly, the rings minimize friction between the piston and the cylinder, allowing for smooth and efficient movement.
