The regulations of diesel exhaust emissions become stricter, so intensive. The present work continues our investigations on engine emissions treatment with discharges assistance1,2. We designed variations of greed shaped DBD plasma sources in order to reduce the NOx content of a diesel engine exhaust, testing it on the different engine operation modes. Discharge frequency has a crucial impact on equipment performance and gas treatment. The plasma source supply frequency was varying from 400 Hz to 28.5 kHz. A 95 % decreasing of NO and 70 % reduction of NOx was obtained. It was found that the discharge application increased efficiency of carbon particles removing 1.4 times.
