Reduction of Detailed Elementary Reaction Schemes by Newly-developed Automatic Scheme Reduction Tool “ASRT” 2007-01-1879

A software “Automatic Scheme Reduction Tool (ASRT)” [1], which was developed by the authors to reduce the number of detailed elementary reactions automatically with CHEMKIN-II code [2], was applied to the reduction of the elementary reaction scheme for gas oil, ethanol and dimethyl ether (DME). It was found that the reduced scheme obtained for a fuel-rich mixture has the capability to predict heat release histories and ignition delay characteristics not only for fuel-rich mixtures, but also for stoichiometric and lean mixtures. As a result, the reduction scheme for DME, which was obtained by the ASRT combined with optimization method, was applied to three-dimensional engine combustion analysis.
