The oxidation of n ‐heptane has been studied in a jet‐stirred flow reactor in the temperature range 950–1200 K at atmospheric pressure for a wide range of fuel‐oxygen equivalence ratios (0.2 to 2.0). A chemical kinetic reaction mechanism developed from previous studies on smaller hydrocarbons and extended to C 6 and C 7 species was used to reproduce the experimental data. Good agreement between computed and measured concentrations of major chemical species was obtained for the entire range of experimental conditions. Sensitivity analyses were carried out to identify the reactions having the greatest influence on the modeling results. The major reaction paths for n ‐heptane consumption and for the formation of the main products have been identified. In addition n ‐heptane ignition delays behind a reflected shock wave measured by other investigators were used to validate the present reaction mechanism at higher temperature and pressure.
