摘　　要：设计了一套NOx选择性催化还原试验装置,介绍了试验装置的功能、系统组成和工作模式,建立了柴油机NOx排放预测模型,分析了NOx起燃特性和最佳还原剂喷射比例,进行了NOx选择性催化还原技术整车试验。An experimental system for the research of selective catalytic reduction（SCR） of diesel NOx has been designed. The makeup and work mode of this system have been introduced. The forecast model of the emission of NOx from diesel engine has been established. This paper also analyzed the light-off characteristic of NOx and the proper dose of the reducing agent. It has done the vehicle test with NOx Selective Catalytic Reduction technology already.

关 键 词：柴油机 选择性催化还原 排放控制
