This study was done for the purpose of achieving the higher removal rate of NO which was exhausted from a diesel engine. The validity of superimposing surface and silent discharge has been discussed. In this experiment, the reactor has four electrodes and consists of double coaxial cylinders. This discharge reactor generated multiple barrier discharges simultaneously in the same space. As a result, the NO removal rate for superimposing discharges mode is higher than that for single discharge mode at the same applied voltage, for the reason of spreading discharge generating area. The NO removal rate for superimposing discharges mode is also higher than that for single surface and silent discharge at the same discharge power. There are two reasons. First, the discharge area spread out into the gap space. Second, the electron is accelerated as the higher electric field.
