Abstract (en)

A method for providing multicharge ignition, i.e. multiple ignition sparks across the same spark plug, to an internal combustion engine is proposed. It comprises a first charging event of an ignition coil followed by a first discharge event to produce a spark, and at least one recharging event followed by a corresponding discharge event to produce a further spark, wherein: the interruption of the primary current following a recharging event is triggered based on the amount of energy stored in the ignition coil. However, each recharging event takes place for at least a predetermined minimum recharging period regardless of the amount of energy stored in the ignition coil.
