Abstract
An ignition coil arrangement for internal combustion engines is embodied so that a housing of an individual ignition coil can be produced economically, and attachment of the ignition coil can be accomplished easily. The ignition coil is configured as a rod-type ignition coil, and the housing is of basically cylindrical shape, since a holding element for fastening the ignition coil is configured in the high-voltage output of the ignition coil itself. Assembly and retention of the ignition coil are accomplished by a direct threaded connection on the high-voltage terminal of a spark plug. For rotational immobilization, a primary terminal of the ignition coil is coupled to a fastenable mating plug as a joining member. The ignition coil arrangement is preferably used in motor vehicles.
