摘要：

The turbo diesel SCR system has been researched and analyzed in this paper. By using software of CATIA, three-dimensional physical model of SCR system has been established, and with software of AVL-FIRE, the boundary conditions have been set, simulated and optimized. In the process of SCR system optimizing, it mainly optimized the pray angle. Compare the effects of processing NOx to obtain batter optimization results. At last the optimization results are compared by bench test, and the experimental results are quite consistent with simulation.
