Abstract

According to results from detailed chemical kinetics modeling, methyl decanoate, MD, shows shorter ignition delays than those of n-heptane over the whole range of the initial temperature. In the second report, the high ignitability in a case without LTO had been elucidated by means of contribution matrices. In the present report, the high ignitability in a case with LTO was analyzed. At the beginning of an ignition process, OH is quickly generated by a path of MD + O2 = MD2j + HO2 to MD2OOH4O2 = MDket24 + OH due to a low C-H bond energy of the α-C atom to the carbonyl group. Therefore, an LTO preparation phase starts with a high OH concentration. In an LTO phase, a large amount of CH2CHO is generated by decomposition of fragmental ketooxy radaicals and aldehyde radicals. As a result, CH2CHO + O2 = CH₂O + CO + OH + 214 kJ increases the LTO end temperature, compared with that of n-heptane.
