DPF(Diesel Particulate Filter) is widely used for the trapping of the soot in exhaust gas by the diesel engine, and a high trapping efficiency is proposed. Here, the fuel addition when active regeneration on DPF is put in question as exacerbation of fuel consumption. So, it is necessary that improvement of fuel consumption by low-temperature regeneration. In this study, the soot oxidation factor was specified by using many kinds of analysis equipment, and properties of the soot to enable the low-temperature regeneration were investigated. As a result, it was suggested that the influence of the primary particle diameter be large in the oxidation of soot. Moreover, primary particle oxidation model was constructed assuming surface reaction of soot oxidation. Calculation results was similar tendency to analyzing results
