Abstract

To evaluate effect of washcoat in SiC-Diesel Particulate Filter (DPF) on the initial PM filtration efficiency, we measured particle number concentration in diesel exhaust gas downstream of SiC-DPF by EEPS. The amount of washcoat materials was changed. Results show that the particle number concentration is largely reduced in washcoated DPF. Thus, it is considered that soot layer is easily formed during initial filtration process. Depending on PM diameter, different effects of washcoat are observed. This is because PM filtration mechanism is different in the range of PM size.
