By combining a DPF, DOC and SCR into one product, the One-Box became a significant aftertreatment development. ... Our improved design also resolved the issue of low NOx conversion efficiency from DEF buildup in the SCR mixing chamber. This problem is common in GHG14 generation One-Boxes—especially when the engine runs in humid climates, and ...Today, vehicles especially diesel engines emitted a large amount of NOx in the urban areas. So, it is required to find ways such as SCR catalysts to reduce this hazard pollutant emission. In this work, a 3D model of cordierite/Pt SCR catalyst has been developed by using AVL FIRE software to analyze the NOx conversion efficiency. The simulation was performed based on experimental tests ...
