The oxidation mechanism of gasoline has been investigated using detailed kinetics mechanisms of gasoline surrogate constructed by Mehl et al. and Hashimoto et al.. To validate these mechanisms, the simulated ignition delay times were compared to those of experiments. The mechanism constructed by Hashimoto et al. predicted the experimental results better than that constructed by Mehl et al., which derived from the difference of the reactivity of n-heptane. Although there are some discrepancies between the ignition delay times calculated by the Mehl et al. mechanism and those calculated by Hashimoto et al., it is found that the oxidation mechanism of gasoline is identical.
