It was utilized to study the micro-textured piston ring-cylinder liner interface tribological behavior at a constant speed, mimicking the mid-stroke state of an internal combustion engine using a linear reciprocating tribometer. The commercially available piston rings with spherical, square dimples and cylinder liner segments were used for the experimentation. SAE20W40 lubricant was supplied to the contact zone's inlet side. The temperature was 150oC, and the load was varied from 80 N to 150 N in the trials. It has been observed that the rings with 300µm square dimples had good frictional resistance at 80 N load compared to the non-textured ring sample. The ring with a 150µm spherical dimple showed better frictional resistance at 150 N load than the non-textured ring sample. In general, 23.62% and 13.79% reduction in coefficient of friction was observed with 300µm square and 150µm spherical dimpled ring at 80N and 150N load, respectively. A better tribological behavior was found in the mid stroke operating circumstances for the textured ring and liner pairs than for non-textured ring and liner pairs working under a mixed lubrication regime.
