Effect of SiC-DPF with High Cell Density for Pressure Loss and Regeneration 2001-01-0191

One technology for removing PM discharged from diesel-powered vehicles is the DPF system. The DPF system brings about increases in pressure loss because PM accumulates in the filter. DPF with a high cell density shows low pressure loss when PM accumulates because of the large filtration area, and in addition, it makes it possible to thin the cell wall because it has a high thermal diffusion ability. For the catalyzation of SiC, the pore size and porosity of the base material were changed. Even when a catalyst is borne, pressure loss which DPF changed pore structure hardly changes. This verification was done based on the theory and by means of experimentation.
