The ignition delay times of toluene-oxygen-argon mixtures with fuel equivalence ratios from 0.5 to 1.5 and concentrations of toluene from 0.1 to 2.0% were measured behind reflected shock waves for temperatures 1270 to 1755 K and at a pressure of 2.4 ± 0.7 atm. A detailed chemical kinetic model has been developed on the basis of a kinetic mechanism proposed by Pitz et al. [1] to reproduce our experimental results as well as some literature data obtained in other shock tubes at pressures from 1.1 to 50 atm. It is found that the present chemical kinetic model could give better agreement on the pressure dependence of the ignition delay times than the previously proposed kinetic models.
