| Abstract: | Many researches indicate that DME is an excellent alternative clean fuel for compression ignition engines, and the latest development of the applications of DME on compression ignition engines were described in this paper. Researchers deeply studied the thermophysical characteristics, spray development characteristics and combustion characteristics of DME by using advanced approaches, theoretically studied the combustion process in-cylinder and the mechanism of realizing ultra low emission of DME and experimentally investigate the performances of DME fueled engines under different operating conditions. Based on those, some countries developed new supply and injection systems of DME which have been successfully applied on vehicles. |
