Based on the characteristics of engine working conditions, the ring/liner reciprocating friction tests were conducted to research the effects of three typical cylinder liner surface topographies (honed surface, large dimple texture and small dimple texture) on the tribological performance of production piston ring pack. The experimental results demonstrated the effects of liner textures are different between three kinds of piston rings: for the barrel-shaped ring-liner pair, the large or small dimple texture has its specific working condition; for the taper-faced ring-liner pair, the oil scraping efficiency and oil distributing stability can be improved by texturing small dimples on liner surface; while the dimple textures have little influence on the friction force of oil control ring-liner pair. In addition, texturing micro-dimples on liner is conducive to reducing the surface wear caused by abrasive wear, and the anti-wear effect of small dimple texture is much better.

缸套表面纹理对不同生产活塞环摩擦学性能的影响

基于发动机工况特点，通过环/缸套往复摩擦试验，研究了三种典型缸套表面形貌（珩磨表面、大凹坑纹理和小凹坑纹理）对生产活塞环组摩擦学性能的影响。 . 实验结果表明，三种活塞环衬套纹理的影响是不同的：对于桶形环-衬套副，大或小的凹坑纹理有其特定的工作条件；对于锥面环-衬套副，通过在衬套表面加工小凹坑可以提高刮油效率和配油稳定性；而凹坑纹理对控油环-衬套摩擦力影响不大。此外，
