Catalyst cannot easily decompose the exhaust gas of diesel engines because of lower exhaust gas temperature. In this study, the decomposition of NO_x in the modulated exhaust gas was studied with plasma discharge reactor as the method. Results showed that NO in N_2 as the dilution gas could be decomposed as much as 80% by this method in an optimized condition, but the decomposition was seriously obstructed by the addition of O_2 in the gas or even NO_x was increased with the increase of O_2 concentration and plasma energy. In addition, it has been understood that the amount of NO_x reduction depends on power consumption and an initial NO level. Moreover the additions of CO_2, HC were studied and analyzed.
