| 摘要:重载荷发动机空气过滤纸是重载荷发动机空气过滤系统的关键材料，其性能优劣严重影响着发动机的工作稳定性和使用寿命。本文首先介绍了空气过滤纸对重载荷发动机的重要性，然后从技术发展的角度将空气过滤纸分为了四代，并对历代空气过滤纸的结构特点、发展动力和关键性能进行了介绍。并讨论了目前重载荷发动机空气过滤纸面临的挑战以及该纸种在我国的发展前景。 |
| Abstract:Heavy-duty air filter paper is the key material in the air filtration system of heavy-duty engines, which affects engine’s stability and life profoundly. In this paper, the importance of air filter paper for heavy-duty engines was discussed firstly. Then, from the standpoint of technological development, heavy-duty air filter paper was divided into four generations and the structural characteristics, development motivation and key performance of each generation of heavy-duty air filter paper were introduced. At last, this paper discussed the current technology challenges of heavy-duty air filter paper and put forward expectations for its development in China． |
