Characterization of High Porosity SiC-DPF

The pore diameter and porosity of SiC-DPF has been increased by elaborating its porous structure. Increasing the porosity of DPF decreases its strength and thermal conductivity. It was clarified how these characteristics affect the performance such as filtration characteristics, low pressure loss, maximum soot loading limit, and thermal response characteristics required for DPF. It was found that the basic characteristics of SiC such as high strength and high thermal conductivity play an important role in its high porosity.
