Ignition delay time measurements were carried out behind reflected shock waves for three isomers of octane, including n-octane, 2,2,4-trimethyl pentane, and 2,3,4-trimethyl pentane, and for 1-octene. Initial concentrations of fuel, oxygen, and argon, and the post-shock temperature were varied systematically to establish the influences of these parameters on ignition delay time. A detailed chemical kinetic reaction mechanism was developed to interpret the experimental results. Overall agreement between experimental and computed results was very good, and the model was used to describe the elementary reaction paths by which these fuels ignite and kinetic differences between these closely related hydrocarbon fuels. 22 refs., 5 figs., 3 tabs.
