As a control device for a spark-ignited hydrogen engine, an ignition signal from a main electrical discharge ignites a hydrogen-air mixture. An ignition signal from a secondary electrical discharge reduces the open voltage of a secondary coil during an intake stroke compared to the open voltage at the end of the main electrical discharge. This signal is sent to an igniter of an ignition device. The open voltage of the intake stroke is thus set to the minimum value of the dielectric breakdown voltage in the spark-ignited hydrogen engine, thereby preventing backfiring.
