With ever growing concerns on environmental pollution, energy security and future oil supplies, the global community is seeking nonpetroleum based alternative fuels to increase the efficiency of energy use. Di-methyl ether (DME) can be used as a clean, high-efficiency compression ignition (CI) engine fuel with reduced NOx, SOx, and particulate matter. DME’s diesel engine-compatible properties are its high cetane number and low auto-ignition temperature. However, physical properties of DME (viz. lower viscosity, lubricity, combustion enthalpy and boiling point) demands modifications to diesel engine internal structures and components. The technology with pure DME as an alternative fuel for CI engine and vehicle is still under development stage. However, if DME is used as an additive fuel with diesel, the relative “goodness” of each fuel might be utilized. This paper analyses the potential benefit of blending DME in diesel fuel in reduction of urban air pollution.
