Abstract:In this paper, the idea of ¡®semiª²decoupling¡¯ is introduced to construct an ethanolª²gasoline chemical reaction model, which uses the small molecule mechanism of H2/CO/C1 as the ¡®core¡¯ with coupling the ethanol skeleton oxidation mechanism and the gasoline toluene reference fuel(TRF) mechanism. By comparing with experimental results available in published literature, the numerical simulation results calculated by CHEMIKIN software can accurately reflect the combustion characteristics of ethanolª²gasoline fuel. Furthermore, based on the sensitivity analysis of H2O, a hydrous ethanolª²gasoline reduced chemical kinetic model is established through integrating the chemical reactions of H2O. And the reduced model is verified by the experimental results of ethanolª²gasoline fuel ignition characteristics.
