NE piston rings – a round thing in constant motion.

Piston rings are an important element of piston cylinders tribology systems. They fulfil various and important tasks:

• gas seal of the combustion chamber
• regulation of the oil film at the cylinder surface
• heat removal from the piston to the cylinder
• minimisation of wear and tear of piston, cylinder and piston rings

Due to the continuous development of the combustion engine, the thermal and mechanical stress on the component increases while at the same time the dimensions are reduced.

Innovative piston ring specifications from NE make a significant contribution to increasing the efficiency and reducing the emissions of modern combustion engines.
