浅谈我国大功率内燃机排放现状及排放后处理发展规划

Discussion on Emission Status and Development of Aftertreatment of High-power Internal Combustion Engine

本文通过对重载车、船舶和铁路行业国内排放标准及实施情况的介绍,阐述了大功率内燃机满足新排放法规所应采取的技术措施,并着重对SCR(选择性催化还原)排放后处理技术现状和未来产业发展规划进行了论述。

This paper introduces the domestic emission standards and their implementation in heavy-duty vehicles,ships and railways,expounds the technical measures to deal with the new emission regulations for high-power internal combustion engines,and focuses on the status and future development prospects of SCR(selective catalytic reduction)technology.
