Abstract: SCR is an effective and critical
technique for controlling and reducing diesel engines′ NOx;emission.In this paper,the
working principle of reducing the NOx;emission,the structures and the
advantages of the SCR technology are introduced.The factors that influence the
performance stability of the SCR system are also mentioned.SCR technology could
fulfill Euro-IV emission regulation.At last,some unsolved problems of SCR
technology for vehicle diesel engine are presented.
Keywords: Diesel Engine;NOx;SCR
