摘　　要：旨在研究生物柴油-柴油混合燃料在船用发动机上应用的相关排放问题,重点围绕混合燃料对船用发动机排放特性的影响,讨论船用发动机应用这种混合燃料的局限性并提出可能的解决措施。研究结果表明,在船用发动机上使用生物柴油混合物后会减少硫氧化物(SO_(X))、一氧化碳(CO)、二氧化碳(CO_(2))、颗粒物(PM)以及碳氢化合物(HC)的排放,但高燃烧速率提高缸内温度进而促进了氮氧化物(NO_(X))的排放。研究认为生物柴油将会减少对进口石油的依赖并降低船舶废气的排放,生物柴油及其混合燃料作为船用柴油替代燃料应用前景光明。The objective of this review is to illustrate the emissions of biodiesel-diesel blends employed in marine engines,focusing on the impact of mixed fuels on marine engine emission characteristics,discussing the limitations of the application of biodiesel-diesel blends in marine engines and suggesting possible solutions.The sulfur oxide(SO_(X)),carbon monoxide(CO),carbon dioxide(CO_(2)),particulate matter(PM)and hydrocarbon(HC)emissions are reduced to a great extent when biodiesel-diesel blends are used in marine diesel engines.The excessively fast burning rate increases the temperature in the cylinder,thereby promoting nitrogen oxides(NO_(X))generation.Research shows that biodiesel will reduce dependence on imported petroleum and reduce emissions of ship exhaust.Biodiesel and its blended fuels have bright application prospects as alternative fuels for marine diesel.
