Every piston is fitted with piston rings. The piston rings must seal off the combustion chamber and the working space from the crankcase and strip the oil from the cylinder walls, thereby regulating oil consumption. They must also dissipate the heat absorbed by the piston during combustion to the cooled barrel. This is one of the most critical component in the combustion engine as the compression and the forces generated in the combustion are linked to the performance of the Ring Sealing Efficiency. There is a continuous development and design up gradation in the improving efficiency, performance and life of this precision part.
