Abstract (en)

[origin: EP0848161A2] The ignition system has at least one ignition coil with a primary winding (7) and a secondary winding (9). The primary winding is connected in parallel with a switching device (19) for connecting the winding terminals (11,13) together in response to a control signal, provided by a control circuit (27). The primary winding of the ignition coil may be coupled to the battery voltage via a Darlington transistor (T2), one end of the secondary winding coupled to earth via an engine spark plug (3), the other end connected to earth via a diode (D1).
