利用DPF内部诱导的常压非热等离子体，对收集的PM直接焚烧或再生DPF进行了研究。该方法是利用等离子体诱导的NO 2和自由基来燃烧沉积在DPF上的碳烟。采用三种DPF蜂窝等离子体反应器对NO转化为NO进行了研究。然后，利用DPF蜂窝等离子体反应器进行再生实验。结果证实了等离子体开启时压降减小，证实了DPF在200℃低温下的再生。
A direct incineration or regeneration of DPF with collected PM was investigated using atmospheric pressure nonthermal plasma which was induced inside DPF. The method is to use the NO 2 and radicals induced by the plasma to burn carbon soots deposited on DPF. Conversion of NO to NO 2 was evaluated using three types of DPF honeycomb plasma reactors. Then, the regeneration experiment was carried out using a DPF honeycomb plasma reactor. As a result, it was confirmed that the pressure drop decreased when the plasma was turned on and the regeneration of DPF was confirmed at the low temperature of 200°C.
