N2 - The air temperature needed to ignite a pre-vaporized fuel/nitrogen mixture in a counterflow was determined over a range of strain rates and pressures for the reference fuels n-heptane and iso-octane. The experiments were modeled with detailed transport and chemistry using semi-empirical reaction mechanisms. Increasing strain rate increased the ignition temperature, increasing pressure decreased the ignition temperature, and the models overpredicted the ignition temperature by about 100 K. The ignition temperature of n-heptane was lower than that of iso-octane. These results were in qualitative agreement with previous data for C2-C4 hydrocarbons. The structure of the fuel molecule and the reactivity of the alkyl radical were responsible for the high ignition temperature for methane, iso-butane, and iso-octane. Original is an abstract.
