Fourteen chemical-kinetic steps are identified, and their associated reaction-rate parameters are given, that enable an existing short chemical-kinetic mechanism (the San Diego mechanism) to be expanded to include the ignition and combustion of dimethyl-ether, over a range of conditions that includes both low-temperature and high-temperature chemistry, as well as both high and low pressures, extending to normal atmospheric pressure. This entails introducing five additional chemical species. Tests of predictions against measured ignition delays, laminar burning velocities, and flow-reactor and jet-stirred-reactor data are reported, that support the success of the mechanism. The results therefore can be useful in combustion computations, especially when larger mechanisms are too time-consuming to be accommodated. (C) 2015 The Combustion Institute.
