| Abstract: | The two dimensional average Reynolds equation and GreenwoodTripp model are applied to examine the problem of mixed lubrication and dynamic wear. Studied are the tribology of system for cylinder pistion ring and the effect of surface roughness. Parameters governing the operation of EQ6100 engine are analyzed. The friction loss power of tribo pairs of cylinder piston ring in EQ6100 engine is calculated and the influencing factors of friction power loss are also discussed. It is found that the tribo pairs of cylinder piston ring is working under mixed lubrication condition. |
