Abstract
In an ignition device of an internal combustion engine which carries out ignition of an air-fuel mixture by repeatedly applying a voltage across electrodes of an ignition plug thereby producing a plurality of discharges, an improvement is proposed in which in the presence of gas flow of which direction is perpendicular to a direction that connects the electrodes with a shortest distance, a time interval between n-th time discharge and (n−1)-th time discharge is so set that a discharge channel caused or proposed by the n-th time discharge is more extended in the gas flow direction than a discharge channel caused by the (n−1)-th time discharge.
