Self-ignition phenomena in shock tube are studied under the cool-flame dominant, negative-temperature-coefficient and blue-flame dominant temperature regimes. Two significant points were demonstrated in the previous paper. One was that the activation energy of methane mixture is low when the temperature behind reflected shock wave sets below 1500K. The other is that the self-ignition does not occur at the tube end in the lower temperature region. This paper describes low-temperature ignition of n-heptane mixture at an equivalence ratio φ=1.0. Almost the same ignition phenomena are established over the temperature ranging from low to high, including three temperature regimes appearing in the piston-compression ignition obtained in a rapid compression machine.
