摘　　要：阐明了内燃机空气过滤纸的低定量化发展方向。首先对使用后的内燃机空气过滤纸进行了扫描电子显微镜观察,说明滤纸可以向低定量发展的根本成因;然后对低定量化滤纸的使用性能和经济性能进行理论分析;最后以一个应用实例验证了滤纸低定量化的优势———在有效延长滤清器寿命的同时还可提高过滤精度。This paper point out the new development trend of engine air filter paper - lower basisweight. Firstly, SEM observation of the used engine air falter paper which shows the key root cause. And then, the operational performance and economic performance of the lower basisweight filter paper is analyzed. In the end, the advantage of lower basisweight of filter paper is proved by an application example. It is obviously that the higher filtration efficiency and longer use life can be reached.
