TLDR
In this paper, a high voltage capacitor is charged, and discharged across a spark gap and ignition electrodes when a threshold value voltage has been attained, which is higher than the breakdown voltage at the ignition electrodes.Abstract:
In the igniting process a high voltage capacitor is charged, and discharged across a spark gap and ignition electrodes when a threshold value voltage has been attained. This voltage is higher than the breakdown voltage at the ignition electrodes. The energy transfer takes place in the starting phase of the ignition spark, i.e. possibly in the breakdown phase of the ignition start. In an appropriate spark plug the presparking path is as near as possible to the ignition electrodes. It has the lowest possible ohmic and inductive resistance, and its threshold value voltage is externally controllable. Between the capacitor and the ignition electrodes the inductance and ohmic resistance of the supply line to the electrodes is as low as possible, at least at frequencies exceeding 50 MHz.read more

TL;DR: In this paper, an inductive circuit is connected in parallel to the spark gap which is so dimensioned that the inductance has a time constant which inhibits substantial current flow through the shunt circuit upon breakdown of a spark gap, but permits flow of current during an arc and glow phase of the spark.
