<p>The diesel particulate filter (DPF) has attracted strong attention as a desirable after-treatment device for the particulate matter(PM) contained in exhaust gas of diesel engine. When particulate matter was deposited on a DPF, the pressure drop increases due to the PM trapping in the surface cavities of the DPF. In this study, we compared the dependence of the shape and depth of the pore of the DPF on the PM trapping process by total model and numerical calculation. We found that the pressure drop and elapsed time of the PM trapping varied, significantly depending on the pore shape of the DPF surface. Further we examined the relative importance of the amount of PM deposit and the surface cavity shape of the DPF, and found that the pressure drop was lower when the shape of surface cavity in DPF became flatter and shallower. The result provides a quantitative evaluation and design of the surface cavity in the DPF leading to better production process of porous ceramic parts. </p>
