TL;DR: In this paper, the influence of regeneration temperature, regeneration flow rate and regeneration time on both regeneration and emission performance by regeneration test bench was discussed, and the optimization active regeneration operating parameters were achieved after considering both regeneration efficiency, total mass concentration and emitted particle average diameter.

TL;DR: In this article, the formation mechanism and influence factors of emitted particle were explored in the regeneration process of diesel engines, and two experimental apparatuses, including a DPF regeneration bench and a diesel engine bench, were built to investigate the particle emission characteristics of DPF during regeneration process in this work.

TL;DR: In this article, the influence of residual ash loading, ash particle size, and ash composition on filter performance due to deposition and regeneration processes on two different testing benches was discussed, and the lowest pressure drop was obtained when the ash loading was 1 ǫ/L in the soot deposition process.

TL;DR: In this article, the impact of inlet transition section length (LT) of particle loading system on the diesel particulate filter regeneration process was investigated and five different transition lengths which lead to different particle distributions inside DPF were tested as well as the different regeneration performance and particle emission characteristics.

TL;DR: In this paper, the influence of ash stack height on the soot deposition and regeneration processes is studied. But the authors focus on the degradation of the CDPF catalytic layer.
