Trapping and regeneration processes in a SiC wall-flow diesel particulate filter (DPF) without a catalyst were investigated in detail through microscopic visualization. By microscopic observation of the cross section and surface, the transition from depth filtration to surface filtration could be observed clearly. The open pores on the wall surface were strongly related to the filtration depth of diesel particulate matter (PM). During the regeneration process, after the soot cake was burnt out, the particulates trapped inside the surface pores were oxidized. As a result, the particulate trapping and oxidation behaviors were strongly dependent on the microstructural surface pores.
