【Abstract】 In order to reduce NO x emissions from Marine Diesel Engines, a designing plan of the scavenging system is proposed. Which, includes equipment that can be kept spraying water vapor into the scavenge air at appropriate time and at appropriate rate according to the load of the Diesel Engine. The increase of relative humidity of the scavenging air can remarkably reduce NO x quantity discharged in the exhaust gas. The idea and the method in this paper may be useful and valuable when you remake the scavenging system of those existed or design that of new Diesel Engines.更多还原
