Focusing on predicting laminar flame speed and important species evolution, a skeletal chemical kinetic model for iso-octane oxidation is constructed by using a practical methodology. The new model consists of 32 species and 111 reactions. Based on the skeletal model target, the methodology considers a combustion mechanism as two parts: a comprehensive part describing reaction processes involving small radicals and molecules as the 'core', and a skeletal one which, in coupling with the 'core', controls the ignition characteristics. The new iso-octane model has been validated against various experimental data including shock tube, jet-stirred reactor, flow reactor, laminar flame speed and HCCI engine, and shows good performance in all the cases.
