摘　　要：为研究二甲醚作为代用燃料掺入汽油时的燃烧特性,利用AVL Fire软件对汽油掺混二甲醚进行了模拟仿真。针对二甲醚的掺入比例分别为5%、10%、15%以及20%进行了模拟,同时模拟了不同温度对燃烧的影响。结果表明:随二甲醚掺入量的增加,混合燃料燃烧速度增快;温度越高,燃烧所达到的压力越高。In order to study the combustion characteristics of dimethyl ether as a substitute fuel blended with gasoline, this pa- per uses AVL Fire software to simulate the gasoline blending of DME. In the process of numerical simulation, the incorporation ratio is 5%, 10%, 15% and 20% respectively, the simulation is carried out to simulate different proportions and the effect of dif- ferent temperature on the combustion. The results show that, with the increase of the content of dimethyl ether, the burning rate of the mixed fuel increases rapidly; the higher the temperature, the higher the pressure of the combustion.
