摘要 介绍了二甲醚(DME)的物理特性和发动机性能研究概况,指出DME是一种理想的柴油机代用燃料。总结了近年来DME在定容燃烧室和发动机缸内的滞燃期、自燃着火过程和燃烧过程的研究现状;叙述了燃烧过程的理论研究和化学反应动力学的研究状况,从理论上探讨了DME的燃烧过程及其实现超低排放的机理。指出了DME发动机燃烧研究的进一步发展方向。 This paper introduces the physical properties of dimethyl ether (DME) and general situation about performance of diesel engine fueled with DME, and shows that dimethyl ether is a perfect alternative fuel for diesel engines. Summarized the research activities on ignition delay time, auto-ignition and combustion in CVA (Constant Volume Apparatus) and engine cylinder in recent years; aim mentioned the research progress on theoretical analysis of combustion, chemical kinetics mechanism, and theoretically analyzed the combustion process and mechanism of ultra low emission of DME. Finally, the technological trends on combustion of DME in engine cylinder are discussed.
