Abstract

Pub_2017_QOI

This work examines the oxidation of a well-characterized, high-octane-number FACE (fuel for advanced combustion engines) F gasoline. Oxidation experiments were performed in a jet-stirred reactor (JSR) for FACE F gasoline under the following conditions: pressure, 10 bar; temperature, 530–1250 K; residence time, 0.7s; equivalence ratios, 0.5, 1.0, and 2.0. Detailed species profiles were achieved by identification and quantification from gas chromatography with mass spectrometry (GC-MS) and Fourier transform infrared spectrometry (FTIR). Four surrogates, with physical and chemical properties that mimic the real fuel properties, were used for simulations, with a detailed gasoline surrogate kinetic model. Fuel and species profiles were well-captured and -predicted by comparisons between experimental results and surrogate simulations. Further analysis was performed using a quantities of interest (QoI) approach to show the differences between experimental and simulation results and to evaluate the gasoline surrogate kinetic model. Analysis of the multicomponent surrogate kinetic model indicated that iso-octane and alkyl aromatic oxidation reactions had impact on species profiles in the high-temperature region; however, the main production and consumption channels were related to smaller molecule reactions. The results presented here offer new insights into the oxidation chemistry of complex gasoline fuels and provide suggestions for the future development of surrogate kinetic models.​​
