Abstract

In this research, the influence of Ash deposition in the Diesel Particulate Filter on the pressure difference across the catalyst has been analytically investigatedby observing the configuration of real Ash deposition and the numerical simulation. Furthermore, from this calculation result, it is suggested that pressure loss can be predicted when Ash deposition density is known, and the importance of a model of Ash deposition mechanism that quantitatively predicts density was shown.
