Probing the Chemical Kinetics of Minimalist Functional Group Gasoline Surrogates

Surrogate mixtures are routinely used for understanding gasoline fuel combustion in engine simulations. The general trend surrogate formulation has been to increase the number of components a mixture better emulate real properties. Recently, new design strategy based on functional group analysis gasolines was proposed using minimal species [minimalist (MFG)—approach]. MFG surrogates (having just one or two components) could experimentally capture ignition delay time (IDT), threshold sooting index, and smoke point different fuels with hundreds components. However, other characteristics were not explored, kinetic modeling reported. These aspects addressed this paper, where behavior various assessed by simulating IDT, jet-stirred reactor oxidation, premixed laminar flame speeds chemical modeling. simulations compared experimental data as well more complex multicomponent (five nine species) surrogates. This study reveals that binary capable accurately
