Dimethyl ether (DME) and methanol are thought to be one of the most promising alternative fuels for IC engines. Meanwhile, previous investigations also have pointed out the good prospects for adopting DME and methanol in IC engines. The experiments in this paper were carried out at idle...

Alternative fuels have become the new energy for future life. Compared with others, Dimethyl ether (DME) is regarded as one of the most promising choices for future internal combustion (IC) engines. Due to some negative properties of ethanol, spark-ignited (SI) ethanol engines always encounter...
