dc.description.abstract© 2019 Published under licence by IOP Publishing Ltd. The autoignition of a stoichiometric propane-oxygen mixture diluted with argon was studied behind reflected shock waves in the temperature range of 1230-1700 K at the total concentration of [M] 50 ∼ 10 -5 mol/cm 3 . Emission signals from electronically excited CH∗ (at λ = 429 nm) and C 2 ∗ (at λ = 516 nm) radicals were recorded. It was found that the CH∗ and C 2 ∗ emission time profiles reached their maxima almost simultaneously over the entire temperature range covered. The temperature dependence of the ignition delay time measured from the time of reaching the maximum by the CH∗ emission signal was simulated within the framework of several published data kinetic mechanisms. It was found that, at temperatures below 1400 K, all the kinetic models tested predict ignition delay times severalfold longer than that experimentally observed. Using a sensitivity analysis to the reaction rate constants in the induction period, the main reactions that affect the ignition delay time were identified.
