An important part of deepening our understanding of the reaction mechanism of natural gas oxidation is validating a detailed model against experimental flame and ignition data. Ignition delays in shock‐heated CH 4 –O 2 mixtures, with and without ignition‐promoting additives, account for most of the available validation data. Most, but not all, ignition delays in such mixtures reported in the literature have been found to agree with calculations done using the GRI‐Mech 1.2 model. Additional reflected shock wave ignition experiments were done to explore possible reasons for the mismatches and to study the promotion of CH 4 ignition by small amounts of C 2 H 6 and C 3 H 8 additives. Empirical correlations were derived that describe ignition delays in CH 4 –O 2 –C 2 H 6 (C 3 H 8 ).
