The discharge characteristics of nanosecond pulse discharge at different pulse voltages and different pulse intervals are investigated based on constant volume bomb. The effects of different discharge parameters on the flame success rate and ignition delay of methane/air mixture are compared. The results show that the coupling between pulses can be reasonably utilized and the utilization rate of discharge energy can be improved by decreasing the pulse interval.The ignition limit of methane/air mixture can be enlarged by increasing the pulse voltage, the pulse number, and decreasing the pulse interval. The ignition delay can be reduced by increasing the pulse voltage and decreasing the pulse interval.
