Influence of honing angle on tribological behaviour of cylinder liner-piston ring pair: Experimental investigation

Research conducted on the influence of honing angle on the cylinder liner surface lacks consensus on the numerical value of the honing angle for the desired performance of the liner-ring tribosystem. The paper presents the results of experimental work performed on the cylinder liner samples honed at different angles (20 degrees-100 degrees) to explore the influence of honing angles under boundary lubrication conditions. Experiments conducted at two distinct sliding conditions (0.2 m/s and 0.3 m/s) using a linear reciprocating tribometer indicated 40 degrees as the optimum honing angle based on the evaluation of tribological characteristics such as the coefficient of friction and the wear.
