At the relatively high temperatures of this study, the ignition
delay times are affected by two important sets of reactions, the fuel
decomposition reactions and the well-known chain branching
reaction H + O2 ) OH + O. For 2-butanone, the fuel decomposition
as well as the chain branching reactions contribute to the ignition
delay, as reported by [1], with the chain branching reaction being
the dominant one. The same is true for 3-buten-2-one where the
chain branching reaction is the dominant one, however, the fuel
decomposition reactions are playing a larger role compared to 2-
butanone, as can be concluded from the sensitivity analysis (not
shown here) of 3-buten-2-one stoichiometric mixture at 1300 K
and 1.5 atm. The reactivity comparison of the two fuels is complicated
because the oxygen percentages for the same equivalence
