Abstract
The invention relates to an ignition device () for an internal combustion engine, more particularly for a hydrogen-fueled internal combustion engine, comprising a primary circuit () and a secondary circuit (), wherein—the primary circuit () has a primary coil (), wherein—the secondary circuit () has a secondary coil () inductively coupled to the primary coil (), a diode () for suppressing a start-up spark, and a high-voltage connector () for connection to a spark plug (), characterized in that a parallel path () is formed electrically in parallel to the diode () of the secondary circuit (), in which parallel path there is arranged an ohmic load resistor () or an electric switch () and by means of which parallel path residual energy, in particular residual voltage, which remains in the secondary circuit () following discharge of the ignition device (), can be extinguished, in particular by feeding the residual energy in the secondary circuit () past the diode (), bypassing the diode ().
