| Abstract: | In this paper,the experiments of the low temperature oxidation of domestic gasoline and iso-octane,the important component in gasoline surrogate model,were carried out in a jet stirred reactor.And the mole fractions of different components were obtained by the composition measurement of domestic actual gasoline.Combined with the composition structure and physicochemical characteristics of actual gasoline,five representative components were selected to construct a suitable gasoline surrogate model and a kinetic mechanism was developed.The low temperature oxidation characteristics of single component fuel and actual gasoline were simulated by using the mechanism,and the results were in good agreement. |
