Piston ring is one of the important parts in diesel engine, and its excessive wear reduces the sealing performance of the combustion chamber, the method on monitoring wear of piston rings with the magneto-resistive sensor is researched from the simulation viewpoint, the research shows that the amplitudes reduce with the increase of the piston ring wear. The theoretical basis for monitoring piston ring wear with a MR sensor is provided.
