| Abstract:The simulation model of piston ring set and cylinder liner was built up based on AVL Excite P&R software. The main structure dimensions of the piston ring as well as the profile type of its working surface were changed to carry out comparative analysis on the performance such as wear, blow by and oil consumption. The main factors influencing the working performance of piston rings and the rules were obtained, thus an optimization programme was put forward. |
| Key words: piston ring set simulation structure performance |
