Reduced Chemical Kinetic Model of n-Heptane for HCCI Combustion

A reduced model of n-heptane is developed on the basic of detailed mechanism by sensitivity analysis and reaction path analysis of every stage of combustion. The new reduced mechanism consists of 35 species and 41 reactions, and it is effective under engine conditions. The effective analysis of it shows that it gives similar predictions to the detailed model in ignition timing, in-cylinder temperature and pressure. Furthermore, the reduced mechanism can be used to simulate boundary conditions of partial combustion and the results are in good agreement with the detailed mechanism.
