“…DME as an additive or an ignition enhancer even enables the use of various other fuels for conventional diesel combustion, dual-fuel operation and HCCI operation. Propane or LPG, hydrogen and natural gas have all been tested as alternatives to diesel with the assistance of DME [22,49,[64][65][66][67][68].…”

Permanent AbstractThis paper reviews the properties and application of di-methyl ether (DME) as a candidate fuel for compression-ignition engines. DME is produced by the conversion of various feedstock such as natural gas, coal, oil residues and bio-mass. To determine the technical feasibility of DME, the review compares its key properties with those of diesel fuel that are relevant to this application. DME's diesel engine-compatible properties are its high cetane number and low auto-ignition temperature. In addition, its simple chemical structure and high oxygen content result in soot-free combustion in engines. Fuel injection of DME can be achieved through both conventional mechanical and current common-rail systems but requires slight modification of the standard system to prevent corrosion and overcome low lubricity. The spray characteristics of DME enable its application to compression-ignition engines despite some differences in its properties such as easier evaporation and lower density. Overall, the low particulate matter production of DME provides adequate justification for its consideration as a candidate fuel in compression-ignition engines. Recent research and development shows comparable output performance to a diesel fuel led engine but with lower particulate emissions. NO x emissions from DME-fuelled engines can meet future regulations with high exhaust gas recirculation in combination with a lean NO x trap. Although more development work has focused on medium or heavy-duty engines, this paper provides a comprehensive review of the technical feasibility of DME as a candidate fuel for environmentally-friendly compression-ignition engines independent of size or application.

“…Chen and coworkers performed experiments with DME and natural gas blends fumigated into a single cylinder Yanmar engine [214]. Through the significant combustion analysis performed, they showed the effect of increasing DME content in the blend on NOx, thermal efficiency and total hydrocarbons [214].…”
