Abstract

Through the DPF regeneration experiment with the DPF inlet temperature slowly increased, the balance point temperature of DPF and pressure-drop characteristics with temperature change in the DPF regeneration process have been determined. Obtained from the experiment, with the DPF inlet temperature increasing, particle oxidation rate is greater than the loading speed, and the DPF pressure-drop decreases slowly. When the DPF inlet temperature rise upto a certain extent, the pressure-drop of the DPF carrier decreases rapidly, due to the particles in the DPF carrier burning speed up. With the follow-up temperature rising in the DPF inlet, the rate of decline of the DPF pressure-drop slows down and gradually stabilizes until the end of DPF regeneration.
