摘　　要：通过建立二甲醚发动机燃烧模型并耦合入KIVA程序中,使其具有二甲醚发动机燃烧过程的数值模拟能力.用数值模拟仿真计算二甲醚发动机燃烧过程,得到缸内炭烟生成量、NOx排放量、不同燃料防热率等实时数据信息.研究结果表明,仿真结果与试验结果相同,基本反映二甲醚发动机燃烧过程的主要规律.经过与原柴油机工作情况的对比分析,表明二甲醚发动机排放性能较好.The combustion model of DIME （dimethylether） engine is established and coupled into KIVA program so that it could have the capacity of numerical simulation of the combustion process of DME engine. The real-time data information including soot formation inside the cylinder, NOT emission and heat rate of different types of fuels is obtained by numerical simulation and calculation of the combustion process of DME engine. The research results have indicated that the simulations results are identical to the experimental ones, which can basically reflect the main principle of the combustion process of DIME engine. The comparative analysis of the corresponding working status of diesel engine and the DME engine has shown that the DME engine has better emission performance.
