摘要
介绍了两种降低柴油机NOx排放的后处理技术:稀薄氮氧化物捕集技术LNT和选择性催化还原技术SCR。具体分析了两种技术的反应机理、工作过程和性能影响因素。阐述了将以上两种技术综合应用,可以满足今后更为严格的排放法规。
Two after - treatment technologies used to reduce NOx emission, namely Lean NOx Trap and Selec- tive Catalytic Reduction, are introduced. The chemical reaction mechanism, working process and factors that affect the performance are analyzed thoroughly. Furthermore, the combination of two technologies could meet the more stringent emission regulations.
