Abstract
The regulations governing marine diesel engine NO_x emission in the International Maritime Organization (IMO) emission standards have become more stringent. Because it is difficult to fulfill these requirements by means of combustion improvement alone, effective aftertreatment technology is needed to achieve efficient NO_x reduction. In this paper, our recent experimental achievements on plasma emission control for marine diesel engines are presented based on our recent papers. Laboratory -scale and pilot-scale experiments are successfully carried out in our studies.
