| Abstract: | The chemical reaction mechanism of NHs SCR technology used to reduce NOx emission was reviewed thoroughly. The advantage such as the improvement of fuel economy, the reduction of NO. and the reduction of PM by combining post-pro- cessing technology with optimization of combustion inside cylinder was discussed. Furthermore, the development of NH3-- SCR application in the fields of vehicle diesel engine at home and abroad was commented in detail. |
