Abstract：In order to improve the performance of diesel particulate filter(DPF)and achieve safety regeneration of DPF,the particle deposition mechanism and the influence of DPF inlet flow rate,particle size,ash deposition amount,filter structure,etc.on the distribution characteristics of particle deposition in DPF are analyzed.The estimation method of carbon deposition in DPF and the influencing factors of DPF regeneration performance are summarized.Through the study of the temperature field of DPF idle regeneration,the upper limit of carbon accumulation in DPF safe regeneration is 11 g/L.In future research,the impact of random vibration on particle deposition and regeneration processes should be considered.This study can provide reference for optimizing the structure and regeneration performance of DPF.
