Round Non Polished Brass SAME Piston Ring Set, For Engine, Size : 10inch, 4inch, 6inch, 8inch

Piston rings are essential components in an engine, as they help to prevent the loss of combustion gases, regulate oil consumption, and ensure efficient heat transfer between the piston and cylinder wall. They are typically installed in grooves in the piston and provide a tight seal against the cylinder wall as the piston moves up and down.

There are generally three types of piston rings: compression rings, oil control rings, and scraper rings. Compression rings are responsible for sealing the combustion chamber and preventing the escape of gases during the combustion process. Oil control rings help to regulate the amount of oil that enters the combustion chamber, while scraper rings are designed to scrape excess oil from the cylinder wall and return it to the oil pan.
