• Spark ignition properties of combustible mixtures under high-turbulence-intensity conditions were studied using an ignition device which was able to vary the energy of capacitance and subsequent inductance sparks, independently. The high-intensity turbulence field was generated by mutual collision of injected mixtures at the center of a cylindrical combustion chamber. From observation of schlieren photographs of flame kernel development, it was found that the turbulence had little effect on the flame kernel shape in the incipient stage of ignition process. The experimental results showed that addition of the subsequent spark to the capacitance one improved ignition ability especially under high-turbulence-intensity conditions, and that high ignition ability appeared with an increase in the ratio of the subsequent spark energy to the total spark energy.
