摘　　要：在一台四缸船舶柴油机上,采用乙二醇单乙酸酯(EGM)作为含氧添加剂,将其以不同的比例添加到柴油中。通过试验表明:提高柴油的乙二醇单乙酸酯比例可以有效降低NOX、CO和CO2的排放,同时会使得燃油消耗率略有提高;增加进口空气湿度也会降低NOX的排放浓度;增加柴油机制动扭矩降低了燃油消耗率,却会引起NOx排放增加。这些结论将为改善船舶柴油机的性能和排放提供参考。In a four-cylinder marine diesel engine, the ethylene glycol monoacetate （EGM） was used as an oxygenatedadditive by mixing into diesel oil in different proportion. It was shown from experimental that increasing ethyleneglycol monoacetate proportion in the diesel fuel can effectively reduce NOx, CO and CO2 emissions, making fuelconsumption higher at the same time. Increasing the inlet air humidity decreased nitrogen oxide emission concentrations.Increasing the engine brake torque reduced fuel consumption, but leading to high NOx emissions. These conclusionswill provide a reference to improving marine diesel engine performance and emissions.
