Abstract

SCR (Selective Catalytic Reduction) technology is the most effective after-treatment technology of DeNOx on vehicle diesel engines. In this paper, a modeling of vehicle diesel Urea-SCR after-treatment system was set up with the method of CFD coupled with chemical reaction dynamic, to make a full-scale simulation and comparison of two Urea-SCR catalyst systems, analyzing the influences of different exhaust temperatures on the emission performance of SCR system, so as to better improve the design of SCR system.
