Abstract: It is shown that, above about 1000 K, ignition delay times for propane and all higher alkanes, as well as for a number of other fuels, can be calculated well by employing rate parameters of only three types of elementary steps, namely C m H n + HO 2 → C m H n−1 + H 2 O 2 , H 2 O 2 + M→ 2OH + M and 2HO 2 → H 2 O 2 + O 2 , only the first of which is fuel specific, the other two clearly being common to all fuels. The prediction of this remarkably simple result relies on a steady-state approximation for HO 2 , as…
