Abstract
Engine power cylinder parts are faced with more severe wear and friction environment. For instance, emission gas recirculation (EGR), one of the most valid technologies related to emission legislation, is known to accelerate wear of piston ring and cylinder liner. Therefore, advanced materials and surface treatments have been developed and adopted successively so that a need exists for an accurate and repeatable friction and wear bench test for various combination of piston ring and cylinder liner that more closely relates to engine test result. This paper introduces accelerative bench wear test method for piston ring and cylinder liner, presents the experimental result of friction and wear properties of piston ring surface treatments that noticed in substitution for hard chrome plating.
