| Zusammenfassung | An investigation of low-pressure-premixed flame combustion chemistry of a binary mixture gasoline surrogate fuel comprising 84 vol% iso-octane and 16 vol% n-heptane has been conducted. The flame chamber pressure was maintained at 20 Torr, while a McKenna burner was used to stabilize a stoichiometric flat flame. The flame speciation was attained via a time-of-flight mass spectrometer. Soft photoionization using single-photon ultraviolet monochromatic beam light has been utilized at The Advanced Light Source (ALS) at Berkeley National Laboratory.The use of this highly tunable soft photoionization light source allowed us to identify main species, intermediates species, and free radicals. In addition, distinction between isomers in the reaction pool was possible in several cases. Comparison with numerical simulations was conducted to shed light on the major differences between the experimental and predicted results. The numerical simulations successfully capture the qualitative trends of most of the presented results. However, some differences were noticed for intermediate/radical species. |
