Diesel soot formation processes were simulated, using several models previously proposed for soot formation and oxidation. The models were assessed and improved by comparing the results with the experiments. Consequently, the model which represented qualitatively the total mass history, the formation position and the spacial distribution of soot was established. The outline and characteristics of the model are as follows. (1) The soot formation model consists of both the Tesner and Farmer models. The soot oxidation model consists of both the Nagle and Magnussen models. The model giving a smaller rate was selected for both models (formation and oxidation). (2) Some of the coefficients in the Tesner model were corrected depending on the in-cylindr volume change. (3) The Farmer model was used only to cover the deficiency of the Tesner model which must be improved due to tempareture dependence.
