Abstract (en)
[origin: WO2007031518A1] The invention relates to a rod ignition transformer for supplying an ignition element, especially a spark plug of an internal combustion engine, with high voltage. A first internal winding (32) and a second external winding (22) are arranged about a main core area (14) of the transformer core coaxially to the longitudinal axis (11) of the rod ignition transformer (30), one of the windings being a primary winding (22) and the other winding being a secondary winding (32). The distance between the peripheral surface of the transformer core (14) and the secondary winding (32) on a first end of the secondary winding (32) is shorter than the distance between the peripheral surface of the transformer core (14) and the secondary winding (32) on the second end of the secondary winding (32). Alternatively or additionally thereto, the distance between the peripheral surface of the transformer core (14) and the secondary winding (32) on a first end of the transformer core (14) is shorter than the distance between the peripheral surface of the transformer core (14) and the secondary winding (32) on the second end of the transformer core (14). The invention also relates to a rod ignition transformer/spark plug combination (40).
