Ignition delay times of 2,5-dimethylfuran(2,5-DMF)/n-heptane/oxygen/argon mixtures were measured in this study. Experiments were performed at the stoichiometric mixtures in the temperature range of 1200-1800K. A blend model for 2,5-DMF/n-heptane blends was developed by combining two selected models for each individual fuel component. According to the combined model, the ignition delay time increases with an increase in the 2,5-DMF addition level, non-linearly. Kinetic analysis was conducted to investigate interaction effects between two fuels. At relatively low blending ratios of 2,5-DMF, the two fuels have negligible impacts on the reaction path of each other. As the 2,5-DMF addition increases to relatively higher levels, decomposition path of n-heptane is significantly changed due to the competition for small radical.
