The reduced elementary reaction model of DME oxidation was made based on detailed elementary reaction model DME 2006. In developing the model, major oxidation reaction mechanisms were considered; 1) The low temperature oxidation mechanism caused by OH radical production through 02 addition and isomerization, 2) Accumulation process of CH2O and H202 before high temperature oxidation, 3) The high temperature oxidation mechanism initiated by H202 dissociation. The new reduced model consists of 41 reactions for 26 species. The validation was made by comparing with the analysis results of the detailed elementary reaction model. The reduced model shows good agreement with the detailed model on ignition delay and mole concentration history of major intermediate species over a wide range of both equivalence ratio and initial temperature.
