In this study, a new plasma/catalyst continuously regenerative hybrid system is introduced to treat diesel particulate matter (DPM). NOx and CO aftertreatment. The catalyst temperature. plasma energy density and exhaust gas characteristics were investigated on the dynamometer test bed. It was reported the smoke removal efficiency has around 70% in the dynamometer test with 80W energy consumption in stationary engine test bed. The plasma/catalyst hybrid system experiments show almost DPM and CO was removed and 30% of NOx removed simultaneously by this system at each engine condition respectively. Considering these results. moreover. in dynamometer experiments show plasma/catalyst continuously regenerative hybrid system is a promising method to regenerate diesel particulate

The direct current(DC) corona discharge has been tested for removal of NO in diesel engine variation with plasma reactors. Each reactor has their own voltage-current characteristics. The results of laboratory experiments show that the DC corona discharge can remove NO with small energy consumption respectively. However, the removal efficiencies in the region of high temperature were not enough to apply to vehicle. Because of the limitation of input energy density. Therefore, it is possible to increase the input energy density using by changing of reactor geometry. This study shows that NO removal efficiency is sensitive to changing the reactor
