DESCRIPTION
A Piston Ring Set, identified by part number 3938197, is a collection of rings that fit onto the piston of an engine. These rings are designed to create a seal between the piston and the cylinder wall, preventing oil from entering the combustion chamber and helping to maintain compression within the engine. The set typically includes several rings of varying sizes and materials, each with a specific function. The top ring is often made of a hard material like chrome or ceramic to resist wear from combustion gases, while the second ring is typically made of more flexible materials like cast iron or steel. The oil control ring(s) are responsible for regulating lubrication in the cylinder walls. Proper installation and maintenance of piston rings are crucial for optimal engine performance and longevity.
