Abstract

The authors investigated the accumulation and oxidization behavior of particulate matter (PM) in a Diesel Particulate Filter (DPF) wall using a newly developed visualization technique. Observations were performed on the conditions required for the PM accumulation and PM forced oxidation processes in test pieces cut from the cordierite DPF. Some notable behaviors were established. In the earlier period of the accumulation process, the PM penetrated the DPF wall, and in the PM forced oxidation process, the PM in the wall was first oxidized, and the nearest part of the PM cake layer to the DPF wall becomes selectively oxidized. The activation energy of PM oxidation that is located adjacent to catalyses in the DPF was calculated from these observation results. The value of the activation energy was close to that found by former researchers.
