This article presents a detailed kinetic mechanism for the combustion of surrogate gasoline fuels (mixtures of primary reference fuels and toluene) that has been developed by modification of a previous mechanism (Andrae et al., 2007). The modifications introduced were: (i) revision of the sub-mechanisms associated with H2, CO and CH4 oxidation and (ii) retuning of rate coefficients of reactions involved in the i-octane oxidation sub-mechanism. The first set of modifications made use of new kinetic parameters evaluated by the CODATA project (Baulch et al. 2006), whereas the second was prompted by a sensitivity analysis of the mechanism obtained after implementation of (i). The resulting mechanism, which describes the low, intermediate and high temperature combustion regimes, is used to study pre-ignition of surrogate gasoline fuels. Comparison of the simulation data with experimental measurements over a wide range of conditions reveals a good agreement.
