In other to predict the ignition and combustion process in a dimethyl ether (DME) injection diesel engine, a new method for optimizing the ignition and combustion model parameters on the basis of the detailed chemical kinetics and genetic algorithm (GA) was investigated. The model parameters in Schreiber's reduced kinetic model, which was used as an ignition model, were optimized for DME by this method. The timescale of laminar chemical reaction in Reitz's model, which was used as a combustion model, was determined by this method. These submodels were incorporated into the authors' GTT code, and the ignition and combustion process in a DME injection diesel engine was numerically analyzed. The validity of the proposed method was confirmed by comparing the calculated result with the experimental one.
