Abstract :
Recently, a novel diesel particulate filter with catalyst coating draws much attention as its great performance of reducing diesel soot. In this paper, we established a mathematical model to predict and describe the pressure drop of DPF, soot loading and regeneration process. The results shows that: the model could effectively reveal the soot mass change in DPF; high flow rate causes high pressure drop in DPF and more frequent regeneration; oxygen concentration in exhaust flow affects the regeneration reaction. When the oxygen concentration equals 10%, the reaction rate and regeneration efficiency reaches highest.
