柴油机颗粒物控制技术研究进展

Research progress in diesel engine particulate matter control technology

随着柴油机的进一步普及,由柴油机颗粒物产生的污染问题日益凸显,因而颗粒物控制技术逐渐成为人们关注的热点。目前,采用柴油机颗粒物过滤器技术(DPF)是最有效的颗粒物控制方法。综述了近年来颗粒物控制技术的研究进展,着重从颗粒物的形成机理、柴油车颗粒物过滤技术方面进行了综述,并对未来发展方向进行了展望。

With the wide use of diesel engines, the environmental problems caused by the diesel particulate matter （PM） have been concerned. Therefore, particulate control technology is focused. Diesel particulate filter technology is considered as the most effective way to reduce the PM emission. The main advances in PM control in the last decade are systematically reviewed in this paper. The particulate formation process and DPF aftertreatment technology are highlighted. The development directions for DPF technology is proposed finally.
