摘要：

A chemical kinetic model consisting of 103 species and 395 elementary reactions has been developed. This kinetic model well describes the formation of polycyclic aromatic hydrocarbons (PAHs) for multi-component gasoline surrogate fuels. Model validation results showed that the predicted PAHs and aromatic precursors using this chemical mechanism were consistent with the experimental results in the premixed flame of ethylene, toluene, n-heptane, and the opposed flow flame of n-heptane. The mechanism is not yet applicable to multidimensional computational fluid dynamics simulations for PAH formation of gasoline combustion. However, compared with the existing kinetic model, the present kinetic model contains fewer species and reactions, so it is closer to the aim of a model for practical applications.
