Abstract

The particulate matter (PM) emitted from the diesel engine is collected and removed by the diesel particulate filter (DPF). When performing PM removal, it is necessary to raise the temperature of exhaust gas, so deterioration of fuel efficiency is a serious problem. Therefore, we aim to propose an optimal DPF structure. In this study, we confirmed the dependence of the shape of the DPF during PM deposition-regeneration process using a numerical calculation. The quick change of the pressure drop and the amount of combustion of PM is smaller when the length of the DPF becomes larger. When the DPF length is long, the residual of PM amount at the outlet of DPF decreases. And the PM on the whole surface burns. When the after 10－15 deposition combustion repetitions, the amount of change of PM shows the same pattern. This model can be used for the optimal design of catalytic DPFs by assuming some modes of operation of the DPF device before the experimental approach.
