A chemical mechanism for ignition and oxidation of multi-component gasoline surrogate fuels

A chemical kinetic mechanism consisting of 89 species and 355 elementary reactions is developed for the prediction of ignition and oxidation behaviors of gasoline surrogate fuels composed of five components, namely, iso-octane, n-heptane, ethanol, toluene, and diisobutylene. Model validation results show that the predicted ignition delay times and laminar flame speeds of the mechanism are consistent with the experimental results, not only for pure mono-component fuels but also for mixed multi-component gasoline surrogate fuels and real gasoline. The mechanism developed here can correctly describe the auto-ignition and combustion characteristics of real gasoline.
