Abstract
The study discusses the catalyst loading position of diesel particulate filter (DPF) and the effect of catalyst loading on the pressure drop. A PM oxidation catalyst is used in the regeneration process to reduce the temperature of the regeneration process. The catalyst is made of expensive precious metals, etc. The amount of catalyst used needs to be reduced. In addition, the catalyst is coated on the surface of the DPF, which narrows the pores and increases the pressure drop. In this study, the numerical model of the previous study was improved, and the effects of catalyst loading position dependence and catalyst loading and exhaust gas temperature on pressure loss were numerically calculated. The results show the PM oxidation behavior depending on the catalyst loading position and the effect of catalyst loading on the pressure drop.
