Description
:
A piston ring is a component of an internal combustion engine that helps seal the combustion chamber and transfers heat from the piston to the cylinder wall. It is usually made of cast iron, but other materials such as steel, stainless steel, or even ceramic can also be used. Piston rings are positioned near the top of the piston and are designed to fit tightly against the cylinder wall. They prevent combustion gases from leaking past the piston into the crankcase, while also preventing oil from leaking into the combustion chamber.
Features
- Designed to seal the combustion chamber and transfer heat from the piston to the cylinder wall.
- Wear resistant.
- Designed for long life.
Applications
Piston rings are an important component of internal combustion engines, providing a tight seal and helping regulate engine temperature. They are used in a wide range of applications, from small engines to large industrial engines, and are essential for ensuring reliable and efficient operation.
