SCR Experimental Study on Reducing NOx Emission of Diesel Engine

NOx emission of diesel engine is an important pollutant to the environment, in the bench test of SCR technology for the diesel engine NOx reducing effect. Diesel engine NOx to ESC test cycle emission by 10.73,down to 3.24; ETC test cycle of the diesel engine NOx emission decreased from 9.533 to 2.98, the diesel engine emissions to meet Euro IV emission standards. Experimental results showed that SCR can effectively reduce NOx emission of diesel engine and the pollution of the environment.
