Laminar burning velocity of gasoline and the gasoline surrogate components iso-octane, n-heptane and toluene

Laminar burning velocities have been measured using the heat flux method on a flat flame adiabatic burner. Measurements were done for iso-octane, n-heptane, toluene, a toluene reference fuel (i.e., a mixture of iso-octane, n-heptane and toluene) and a commercial gasoline. The laminar burning velocities of the toluene reference fuel were in correspondence with the laminar burning velocities of the commercial gasoline. Measurements were done for an equivalence ratio from 0.7 to 1.3 and for a range of temperatures between 298 K and 358 K. The temperature dependence of the fuels is shown and the measurements are compared to literature data and simulations using reduced kinetic models. (C) 2013 Elsevier Ltd. All rights reserved.
