摘　　要：废气再循环技术是控制氮氧化物(NO_(x))排放最有效的措施之一。通过梳理欧洲、美国、日本以及我国排放标准的演变过程,研究了NO_(x)排放限值的变化,探讨了基于排放标准的废气再循环技术路线,展望了其发展趋势。EGR is one of the most effective measures to control NO_(x) emissions.This paper reviews the evolution process of emission standards in Europe,the United States,Japan and China,studies the change of NO_(x) emission limits,discusses the technical route of exhaust gas recirculation based on emission standards and looks forward to its development trend.

关 键 词：排放标准 废气再循环技术 发展趋势
