Abstract:A method for cetane number(CN)prediction based on the predicted ignition delay of a skeletal primary reference fuel mechanism has been proposed in our previous work.Because the cetane number of components in the primary reference fuel composing of n-hexadecane and iso-cetane is between 15 and 100,the prediction method is only valid for the fuel with the cetane number from 15 to 100.To expand the operating range of the predicted cetane number,a supplementary method was proposed in this study.In the supplementary method,the fuel with the cetane number beyond 15—100 was predicted by linear fitting based on the cetane number of the components in blend.This method was referred to the extension method.The result shows that the extension method can well predict the fuel’s cetane number which is beyond 15—100.Moreover,the cetane number of components is not required in the exten-sion method.However,this method has the characteristic of error accumulation.
