汽车发动机活塞气环结构改良的技术研究

Study on the improvement of piston air ring structure of automobile engine

通过活塞环-气缸的摩擦损失对汽车动力性、经济性和可靠性的影响因素分析,提出一种新型汽车活塞环表面结构,增加了活塞环与气缸的自润性,减少了干摩擦出现的几率。

Based on the analysis of the factors affecting the dynamic, economic and reliability of piston ring and cylinder, a new type of automobile piston ring surface structure is proposed, which increases the self-running property of piston ring and cylinder and reduces the probability of dry friction.
