In reciprocating internal combustion engines, one of the most important aspects to be clarified is the frictional characteristics between the piston rings and the cylinder liners for the reduction of frictional loss or the solution of problems such as scuffing and wear with the advances in engine performance achieved in recent years. In the present study, an improved floating liner method supporting the cylinder liner by means of hydrostatic bearings was developed to measure accurately the frictional force of the piston assembly as a function of the crank angle in firing operation.
