Abstract
In order to remove NO from diesel exhaust gas, non-thermal plasma methods have been extensively studied. However, it is known that one of the problems of the de-NOx process by non-thermal plasma is the relatively high energy consumption of the de NOx process. In this paper, we tried to solve this problem by using a water emulsion fuel. Since the use of water emulsion fuel reduces the combustion temperature in the engine, the NO concentration at outlet of the engine should decrease considerably. We prepared a water emulsion fuel with different water content, and carried out NO removal experiments for diesel exhaust gas by both direct discharge and by an ozone injection methods. The experiments showed that a large reduction of discharge power for de-NOx process could be achieved.
