Optimum design through tuning techniques

A piston ring must have both spring-like tension and the properties to become a true circle when closed. NPR's piston rings serve to seal combustion gas, control lubricating oil, dissipate heat, and prevent wear and seizure under the severe conditions of operation. Now that engines are required to be more compact, lighter, and more sophisticated in performance, the choice of piston ring materials has been widened to include steel in addition to the traditional cast iron. Moreover, in order to enhance their wear resistance and durability, the rings also undergo various surface treatments including nitriding and PVD treatment.
