AbstractA detailed shock tube investigation on the ignition delay times in mixtures containing n‐hexane and oxygen diluted in argon is reported. The product distribution of the pre‐ignited mixtures was also investigated and a computer modeling of the combustion kinetics was performed. The experiments covered the temperature range 1020–1725 K at pressures of 1–7 atm. A computer simulation was performed with a large number of elementary reactions (386), which was then reduced to a scheme containing only 76 reactions.
