摘要
选择催化还原技术(SCR)是降低车用柴油机NOx排放的机外措施之一。阐述了SCR技术的机理、系统组成及工作原理,介绍了国内车用柴油机SCR技术的研究情况及还需解决的问题。
Off-engine measure is an effective measure to control NOx exhaust emissions from diesel vehicle and the key technology to control diesel engine emissions.Selective Catalytic Reduction（SCR） is one of off-engine measures to reduce NOx emissions from vehicular diesel engines.This paper introduces basic theory,the structure of system and working principle of SCR measure and emphasizes on the application status of SCR measure in domestic and the existing problems that should be solved.
