Abstract	Researchers designed a novel optimized chemical kinetic reaction mechanism for the oxidation of PRF (primary reference fuel) instead of gasoline, for the multi-dimensional CFD (computational fluid dynamics) combustion simulations of internal combustion engines. To conduct in-depth research for combustion phenomenon of internal combustion engines, an optimized reduced PRF mechanism including more intermediate species and radicals was developed. The developed mechanism contains of iso-octane (C8H18) and n-heptane (C7H16) surrogates, which contains of 51-species and 193 reactions. Compared with many other mechanisms of PRF, more reactions of C0–C1 oxidation were added in the present mechanism. In order to improve the performances of the model, the developed mechanism focused on the improvement through the prediction of the ignition delay time. The developed mechanism has been validated against various experimental and simulation data including shock tube data, laminar flame speed data and HCCI (homogeneous charge compression ignition) engine data.
