“…The validated model is tested against high-temperature/high-pressure single-shock-tube species profiles for toluene [20] and a single-zone engine model is used to evaluate how well the validated kinetic model can capture autoignition in two different HCCI engines [21,22]. The final version of the model can predict the experimental results from all these diverse sources reasonably accurately.…”

“…Much research [1][2][3][4][5][6] is performed regarding kinetic mechanisms, the auto-ignition for many compounds and HCCI combustion. A great part of the HCCI investigations [7][8][9] use the socalled Primary Reference Fuels (PRF) such as iso-octane and n-heptane. [To account for aromatics in gasoline and especially diesel, mostly toluene is added for this purpose [10-14].…”

To acquire a high amount of information of the behaviour of the Homogeneous Charge Compression Ignition (HCCI) auto-ignition process, a reduced surrogate mechanism has been composed out of reduced n-heptane, iso-octane and toluene mechanisms, containing 62 reactions and 49 species. This mechanism has been validated numerically in a 0D HCCI engine code against more detailed mechanisms (inlet temperature varying from 290 to 500 K, the equivalence ratio from 0.2 to 0.7 and the compression ratio from 8 to 18) and experimentally against experimental shock tube and rapid compression machine data from the literature at pressures between 9 and 55 bar and temperatures between 700 and 1400 K for several fuels: the pure compounds n-heptane, iso-octane and toluene as well as binary and ternary mixtures of these compounds. For this validation, stoichiometric mixtures and mixtures with an equivalence ratio of 0.5 are used. The experimental validation is extended by comparing the surrogate mechanism to experimental data from an HCCI engine. A global reaction pathway is proposed for the auto-ignition of a surrogate gasoline, using the surrogate mechanism, in order to show the interactions that the three compounds can have with one another during the auto-ignition of a ternary mixture.2
