DESCRIPTION
A Compression Piston Ring, identified by part number 4058967, is a circular band typically made of metal that fits tightly around the piston of a truck engine. Its main function is to create a seal between the piston and the cylinder wall, preventing combustion gases from escaping and ensuring maximum compression in the combustion chamber. It also helps to prevent oil from entering the combustion chamber and promotes efficient heat transfer away from the piston. Over time, these rings can wear or become damaged, leading to decreased engine performance and increased oil consumption. Therefore, it’s important to regularly inspect and replace compression piston rings as needed to maintain optimal engine function.
