Piston ring/liner interface can contribute as much as half the total friction loss in internal combustion engines, with the resulting wear leading to reduced energy efficiency and raised emissions. A new ASTM International standard provides a method to more accurately measure small amounts of wear on curved piston ring segments and their counterfaces after lubricated bench-scale testing. “Coupled…
