摘要
从环保与节能的角度分析了柴油机采用新型清洁燃料的重要性,介绍了二甲醚(DME)和其他代用燃料的物理化学特性。总结了近年来对DME氧化和燃烧的化学动力学研究情况,论述了柴油机燃用DME实现无烟化、超低排放的机理。最后分析了柴油机采用DME作为代用燃料时燃油系统的选择和匹配所需要解决的关键性技术问题,讨论了DME发动机进一步研究和发展方向。
This paper overviewed the investigation and promising of DME as an alternative fuel for diesel engine. From the standpoint of energy source and environmental protection, the author analyzed the importance and necessaiy to develop a new clean alternative fuel for diesel engine, introduced the physicochemical performances of DME. Organized the research activities on DME combustion and chemical kinetics in recently years,discussed the mechanism of super low emissions with smoke-free of DME. At last,analyzed the key problem of fuel delivery system when diesel engine fuelled with DME, and the further R&D tendency of DME.
