摘　　要：由于DME(二甲基醚 )有良好的压燃着火性能以及不需特别的措施就能达到超低排放标准 ,因而成为柴油发动机一种很有潜力的替代燃料。多年来各国对DME作为柴油的代用燃料作了大量的研究 ,对DME的喷雾过程、自燃着火过程和燃烧过程等方面有了较为深入的了解。DME(dimethyl ether)becomes a potential alternative fuel,for its excellent autoignition performance and capacity to meet ULEV emissions standards for diesel engines without any exhaust gas after treatment.DME,as a kind of alternative fuel of diesel engine,has been researched by the worldwide engine researchers for many years and a profound understanding of the spray,autoignition,and combustion process of DME has been acquired.On the basis of these research results,a novel electrionically controlled injection system has been developed.It will further release the potentiality of DME.
