Abstract
Based on the two-dimensional average flow model and asperity contact m odel, a theoretical model for the non-axisymmetrical analysis of pisto n ring lubrication has been suggested in this paper. The two-dimension al distribution of oil-film thickness between the piston rings and cyl inder wall is obtained. Results show that the oil-film thickness along the circumference is non-uniform. Starvation is also considered in th e model. The effect of secondary motion of piston assemblies on the lu brication property of the piston ring pack has also been studied.
