  • Ignition coil for an internal combustion engine
    Patent number: 7952456
    Abstract: The invention relates to an ignition coil for an internal combustion engine. Said ignition coil comprises a primary coil base (2) carrying a primary winding (1) and having an especially cylindrical shape, a low voltage connection area (10) for connecting the primary winding (1) to a low voltage, a secondary winding (3) inductively coupled to the primary winding (1) and disposed on an especially cylindrical secondary coil base (4), for providing a high voltage for the spark plug of the internal combustion engine. The primary coil base (2) and the secondary coil base (4) are mounted concentric to one another. The ignition coil also comprises a high-voltage connection area (5) in which the secondary winding (3) contacts the spark plug. The aim of the invention is to improve the ignition coil of the aforementioned type with respect to its electromagnetic compatibility.
