- Abstract
Diesel particulate filter (DPF) can effectively reduce the exhaust emissions of PM. In this paper, FIRE AVL software is used to establish the numerical model of DPF soot capture and heat regeneration, and the validity of the model is verified. This paper simulates and calculates the process of DPF soot capture and heat regeneration, and analyzes the influence of different factors on the process of DPF soot trapping and heat regeneration. The analysis shows that: within a certain range, the larger the CPSI (hole mesh), the pressure drop of DPF rises more gently; the greater the initial soot density is, the greater the DPF pressure drop rises; the greater the exhaust flow rate, the greater the pressure drop across the DPF; the higher the oxygen content of the exhaust gas, the faster the burning of soot in the regeneration process, the higher the maximum temperature of the reaction; the faster the temperature of the regeneration process rises, the time of reaching the maximum temperature point is earlier; the greater the inlet air mass flow rate is, the earlier the peak of the maximum temperature occurs, the regeneration is more rapid, but in the regeneration process it is necessary to choose the appropriate inlet gas quality flow.
