摘　　要：介绍二甲醚燃料的理化性质和特点，阐述二甲醚在柴油机上的研究现状，并指出今后的研究方向。二甲醚燃料能够实现发动机高效、超低排放和柔和压缩燃烧。能够彻底消除柴油机的碳烟，大幅降低NOx排放，燃烧噪音可降低10-15dB。柴油机使用二甲醚作为代用燃料可以节约石油资源，减少排放污染。An introduction is made to physical and chemical properties and characteristics of dimethyl ether fuel and the research status of DME engine at home and abroad, cind the direction of future research is pointed out. DME engine can achieve high efficiency, ultra-low emissions and soft compression combustion. Carbon smoke given off by diesel engines can be eliminated completely, NOx reduced greatly, and combustion noise reduced by 10 - 15 dB. If DME is used as substitutive fuel in diesel engines, petroleum can be saved and waste gas pollution reduced.
