Combustion and Emission Characteristics of SI and HCCI Combustion Fueled with DME and OME

DME has been considered an alternative fuel to diesel fuel with promising benefits because of its high reactivity and volatility. Research shows that an engine fueled with DME will produce zero smoke emissions. However, the storage and the handling of the fuel are underlying difficulties owing to its high vapour pressure (530 kPa @ 20 °C). In lieu, OME₁ fuel, a derivate of DME, offers advantages exhibited with DME fuel, all the while being a …
