  "textContent": "The invention relates to a method of igniting a spark in an electrical plug provided in a circuit and having a discharge gap for yielding a plurality of consecutive spatially distributed sparks per single ignition event, wherein the method comprises the steps of: applying a breakdown voltage pulses U to the discharge gap with a period of maximally 1 millisecond, said discharge voltage pulses having a leading edge; limiting conductivity current over the discharge gap to below of about 10 mA during an interval corresponding to the said leading edge or ensuring that a conductivity current across the discharge gap is substantially zero during an interval of at least 5% of the said period. The invention further relates to an ignition system comprising a power generator connected to a spark plug using an optional transmission line, preferably comprising coaxial cable. The invention still further relates to an internal combustion engine and a vehicle.",
