Abstract

We studied electrical parameters of the ignition system generating a self-stabilized high-voltage pulsed arc. We observed 2 current pulses generated by the system. The first current pulse appears in the time interval 0 to 3 μs as a consequence of a high-voltage pulse (about 20 kV) supplied to the spark gap. The discharge current after the first current pulse gradually increases up to 3 ± 1 A, when the second current pulse appears. The delay between two current pulses increases with growing spark gap size from 60 to 125 µs, corresponding to gap size 0.5 mm and 13 mm, respectively. The energy input in the developed ignition system is given by the discharging of two capacitors. The total energy released in the first current pulse does not exceed 163 mJ. The experimental-computational method was used to measure the energy input for the second pulse. It was found out that the main part of the discharge energy is released in the second current pulse where the deposited energy exceeds 231-541 mJ. Relatively high efficiency of energy deposition in the gas discharge channel up to 58 % was observed, increasing with expanding spark gap size to 13 mm.
