In this study, using carbon particles as model diesel soot, we evaluated the filtration performance of SiC-DPF. We changed the flow volume rate to examine the filtration velocity on the property of soot cake during the surface filtration. The flow rate was from 4.5 to 40.4 L/min. It was found that, as for the filtration performance, the pressure drop increased at higher flow rate. Based on results, we discussed the density of soot cake formed during the surface filtration.
