Popis: A single pulse reflected shock tube was used to investigate iso-octane ignition over the temperature range of 900-1400 K at a pressure of 1 atm. To account for the anticipated long ignition delay times at the lower temperatures, long shock tube dwell times (12 ms) at lower temperature and near atmospheric pressure were achieved by using argon-helium mix as a driver gas. Chemical thermometer experiments were conducted to remove any uncertainties in determining post-reflected shock temperatures. The ignition delay data obtained in this study are in good agreement (in the overlap region) with the iso-octane ignition data from a previous shock tube study. However, the activation energy of iso-octane ignition obtained in this study in the lower temperature region (
