Abstract (en)
[origin: EP0412679A1] An ignition coil for developing a spark plug firing voltage. The ignition coil is comprised of first and second parts (12,14) that are formed of iron particles in a binder of electrical insulating material which define axially spaced end wall portions (12D,14D). The parts are connected by a core member (16) that is formed of magnetic material. A primary winding (18) is disposed about the core member and a secondary winding (22) is disposed about the primary winding. An axially extending part (12B,14B) that is formed of magnetic material is located outside of the secondary winding and magnetically connects the end wall portions.
