摘要
The improvement of lubrication of piston ring-cyinder liner is always in demand, andsurface roughness behaviour plays a very important role. The present paper will explore this be-haviour and investigate how the inlet roughness of ring influences the lubrication of pistonring-cylinder. The quantitative results of this combination of surface roughness on friction force, oilfilm thickness and frictional power loss are given and discussed.
