  text: <jats:p>Iso-octane is frequently used as a surrogate fuel or as a component
    in primary reference fuel blends when low-temperature combustion strategies in
    engines are investigated. To develop control strategies for these engines, the
    reaction kinetics of iso-octane must be known starting from the low temperatures
    and intermediate pressures before ignition to the high temperatures and pressures
    of combustion. This work adds new experimental data sets to the validation data
    for reaction mechanism development by investigating the oxidation of iso-octane
    in stoichiometric mixtures in a flow reactor at pressures of <jats:italic>p</jats:italic>
    = 1, 10, and 20 bar and 473K ≤ T ≤ 973 K. The experimental data are compared to
    simulations with recent reaction mechanisms [Atef et al., Combustion and Flame
    178, (2017), Bagheri et al., Combustion and Flame 212, (2020), Cai et al., Proceedings
    of the Combustion Institute 37, (2018), Fang et al., Combustion and Flame 214,
    (2020)]. The comparison between experimental and simulated mole fractions as function
    of temperature show reasonable agreement for all investigated pressures. In particular,
    the experimentally observed onset of low-temperature reactivity above a certain
    pressure, the shift of the negative temperature coefficient (NTC) regime with
    increasing pressure to higher temperatures, and the acceleration of the high-temperature
    chemistry are captured well in the simulations. Deviations between experimental
    and simulated results are discussed in detail for the reactivity of iso-octane
    and some key intermediates such as 2,2,4,4-tetramethyl-tetrahydrofuran, iso-butene
    and acetone at low temperatures.</jats:p>
