“…by Flynn et al [7], Foucher et al [8], and Masurier et al [9,10]. Using an ozonised liquid fuel instead of gaseous ozone directly, may have the advantage of better cycle-to-cycle control, ease of stratification as well as limiting ozone destruction and energy losses occurring due to gaseous compression and injection of ozone.…”

The autoignition timing of 1-hexene was controlled in a Homogeneous Charge Compression Ignition (HCCI) engine by reacting the fuel with ozone-containing air prior to its combustion. The experiments were conducted in a single cylinder research engine instrumented with a cylinder pressure sensor. The fuel was chemically characterised using Nuclear Magnetic Resonance (NMR) spectroscopy before and after its reaction with ozone. The NMR analyses showed that this preliminary reaction produced several oxygenated products within the fuel, and was likely to have resulted in the formation of ozonide molecules having a peroxidic structure with several oxygen molecules in series. To understand how this would affect the ignition reactions, the ignition process was modelled numerically using a single-zone chemical kinetic reactor model. The modelling suggested that peroxide molecules decomposed during the compression of the reactants in the engine and advanced ignition timing by promoting early decomposition of the fuel through the formation of radicals.

“…The recommended rate constant of reaction (38) [65] is adopted here. Reaction (X17) with the rate constant inherited from Starik and Titova [14] is implemented in the MSU mechanism.…”

“…It was demonstrated [34] that due to the incompleteness of the MSU mechanism (absence of many reverse reactions) it predicts an incorrect balance between O atoms, excited and ground state oxygen in ozone flames. It should be noted, however, that ozone reactions from the MSU mechanism [25,30] excluding excited oxygen species are mostly balanced, and their implementation in the recent studies of combustion enhancement by ozone [6,[35][36][37][38][39] is justified. Yet, conclusions based on the complete set of reactions taken from the MSU mechanism by Ombrello et al [7], and by Bourig et al [26], should be treated cautiously.…”

“…These results show that ozone acts on the beginning of the combustion. Foucher et al [45] investigated the ozone seeding on an HCCI engine fuelled with n-heptane. They observed that low concentrations of this oxidizing chemical species are needed to strongly advance the combustion phasing which is combined with a higher heat release rate on the cool flame.…”
