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。在此基础上发展了专为DME使用的电控喷射系统 DME (DME) is a promising alternative fuel for diesel engines because of its good flammability and fire performance and the need to meet ultra-low emission standards without special measures. Over the years, many countries have made a great deal of research on DME as a substitute fuel for diesel fuel, and have a better understanding of the DME spray process, spontaneous combustion process and combustion process. On this basis, developed for the use of DME electronically controlled injection system
