Wear of cylinder liner due to friction load of piston ring with various surface temperature

Abstract

Wear on the cylinder liner as a combustion chamber is generally because of frictional loads by the piston rings. In addition, high temperatures that occur in the combustion chamber may accelerate the wear of the cylinder liner and shorten the service life of the cylinder liner. In this work, the wear test will be carried out on the cylinder liner of a diesel engine due to the friction load by the piston ring with various temperatures of the contact surface between the cylinder liner and the piston ring. The wear test is carried out on a linear reciprocating pin-on-plate wear test machine with the temperature of the contact surface varied from room temperature of 30 to 400°C. The results show the wear rate of the cylinder liner increases with increasing surface temperatures progressively. The wear mechanism occurs possibly by abrasive or adhesion wear and oxidation wear.
