We propose a new technique for simultaneous decomposition of diesel particulate material (DPM) and nitric oxides (NOx) exhausted from a diesel engine. DPM and NOx are collected in a reactor using an electrostatic precipitation and a honeycomb-shaped adsorbent, respectively. After the sufficient collections, a dielectric barrier discharge (DBD) is generated in the closed space to condense and decompose DPM and NOx. DPM and NOx were decomposed simultaneously and effectively by the DBD, which act as the oxidant and reductant, respectively. It is considered that this technique is the most suitable for the decomposition of DPM and NOx with small concentration and high gas flow rate.
