SCR system for diesel engine vehicles is a device to reduce NOx from the emission gas of the diesel engine causing selective catalytic reaction by utilizing a metal catalyst with ammonia, NH₃, or HC as a reductant, and the device is recognized as a unique technology to meet future emission regulation for NOx such as Euro-V (2008). Under the current circumstance that the development for diverse post process technologies is in process, in this study, we evaluated the pressure and uniformity inside of SCR TYPE CEM(Catalyst Exhaust Muffler) reducing NOx among noxious gasses, through design and CFD(Computational Fluid Dynamics) analysis.
