A Reduced Element Reaction Mechanism for Methanol-PRF Blended Fuel

The main reaction course of primary reference fuel(PRF),methanol and their blended fuel was analyzed and the mutual influences between elementary reactions during the methanol-PRF blended fuel combustion were researched based on the detailed reaction mechanism.The simplified reaction mechanism,which contained 75 reactions and 45 substances,for methanol-PRF blended fuel was constructed.In addition,the mechanism was testified by shock tube experiments,flow reactor experiments,detailed mechanism calculated results and HCCI engine experiments.The results show that the simplified mechanism calculated results have a good agreement with the experiments results and the detailed mechanism calculated results.
