Abstract
Based on chemical kinetics, a reduced chemical reaction mechanism was developed for simulation of combustion process for n-heptane, by temperature sensitivity analysis, composition and reaction rate analysis. The final mechanism consists of 43 species and 63 elementary reactions. The reduced mechanism was validated by comparing with the detailed mechanism on the concentration variation of reactants, major intermediates and the final product of combustion. The difference between temperature and pressure in cylinder was also considered. The results show that the analysis is reliable and practical.
