The purpose of this research is to get fundamental knowledge and to experimentally understand about combustion characteristics of the fuel mixture. This paper shows the Homogeneous Charge Compression Ignition (HCCI) characteristics of a mixture of n-Heptane and iso-Octane in a rapid compression machine. The experimental matrixes cover the n-Heptane mixing ratios, r n-Heptane, ranging from 0 to 100vol% and the equivalence ratios ranging from 0.1 to 0.6. The experimental study on the effect of mixing fuels focuses on the low temperature oxidation reaction temperatures, TL, the high temperature oxidation reaction temperatures, TH, the low temperature oxidation reaction starting times, tL, the high temperature oxidation reaction starting times, tH, and the degeneration period. The results show that as rn-Heptane decreases, tL and tH become longer and TL and T H increase by 30K. As the equivalence ratio increases, tL becomes longer but tH is not a function of equivalence ratio. Moreover, for the partial equivalence ratio of n-Heptane lower than 0.2, t L, tH, TL and TH are a function of partial equivalence ratio of n-Heptane, while for the partial equivalence ratio of n-Heptane higher than 0.2, there are no effects on any oxidation reaction.
