A Novel Reduced Reaction Mechanism for Diesel/2,5-Dimethylfuran Engine Application

The application of 2,5-dimethylfuran (DMF) as an alternative fuel for internal combustion engines has been gaining popularity. However, it rarely studied in previous research on the chemical kinetics DMF engine simulations. In present study, a reduced n-heptane/toluene/DMF-polycyclic aromatic hydrocarbon (PAH) reaction mechanism containing only 78 species amongst 190 reactions was proposed and applied to predict emissions diesel using diesel/DMF blend fuel. First, detailed from literature chosen combined reduction methods under engine-relevant conditions. Second, incorporated into existing n-heptane/toluene-PAH establish three-component chemistry mechanism. Third, predictive capability improved by adjusting rate constants selected gas-phase reactions. Subsequently, compared validated with experimental measurements shock tube ignition delay times premixed flame profiles acquired published papers. Moreover, new data conventional were used evaluate developed Overall, predicted results obtained this n-heptane/toluene/DMF-PAH are reasonable agreement available experiments.
