Modern engine manufacturers are under pressure to continuously improve the performance of diesel engines. Government requirements and customer demands drive significant changes to power cylinder designs. Great efforts are being made to reduce emission levels and increase operating efficiencies. The power cell unit (PCU) environment is becoming more aggressive at the same time that peak cylinder pressures are increasing. Engines are expected to perform at this high level throughout their operating life with little to no degradation in performance. Besides that, greater emphasis is also being placed on fuel efficiency of the engine. In order to meet these challenges the design of a modern ring pack should consider the utilization of high wear resistance coatings aligned with new geometries to enhance oil film control and reduce friction.
