Experimental Study on the DPF Regeneration Based on Non-thermal Plasma Technology

摘要

Diesel particulate filter (DPF) are considered to be the most effective means to reduce particulate emissions, and the key of DPF lies in their regeneration. O_3 and O which have strong oxidability can be produced by non-thermal plasma (NTP) reactor. PM can be decomposed by these active substances to generate CO and CO_2. The results show that PM deposited in the DPF can be removed by NTP technology without any catalyst and DPF can be completely regenerated at a lower temperature.
