Characterization of Thin Wall SiC-DPF

We examined a filter structure of a SiC-DPF, and found that the reduction in a wall thickness is effective in decreasing a pressure loss. And we made it clear how this reduction in the wall thickness influences the performances of the DPF, that are the filtration efficiency and the accumulated soot mass limit which are important for the DPF. From the results of this study, it can be seen that the filter structure which is suitable for the catalyzed DPF should be controlled in a porosity and the wall thickness in proportion to an amount of catalyst required.
