A phenomenological soot model coupled with detailed chemistry was introduced into the 3-D CFD code KIVA-3V. The model treats soot formation as four global stages including particle nucleation, surface growth, surface oxidation, and particle coagulation. In paper Particulate Matter Formation process of a Diesel engine under various O_2 concentration conditions were analyzed. As a result, predicted in-cylinder pressure and RHR histories have good agreement with measured ones. It can be predicted qualitative trends of measurement data of soot emission under wide range of O_2 concentration conditions.
