Abstract (en)
[origin: EP0131905A2] A contactless magnet ignition system comprises a first core (6) of U-shaped cross-sectional configuration carrying an ignition coil (10, 11) on its central portion (7). A second core (9) carrying a control winding (23) is disposed outside of the primary winding perpendicular to the main axis of the first core (6) and spaced therefrom within the space defined between the legs (8) thereof. A permanent magnet rotor component (3 to 5) is adapted to induce respective voltages at the terminals of the primary winding (10) and the control winding (23). A transistor (19) is controlled by the control winding (23) for interrupting the current flowing through the primary winding (10) so asto induce in the secondary winding (11) a voltage adapted to cause a spark to be generated across a spark plug (12).
