While the breaker contact is closed, is included of the ignition device of the invention further includes the base electrode of the transistor at the same voltage as the collector electrode, so that complete conduction of the Tränsisfer obtained and the increase in the tranaistor transfer sun temperature is audible to a minimum.

Finally, the ignition device is part of the invention all electronic control devices with one Sin coil connected, no da3 the entire device can be exchanged directly for an existing ignition coil, and this eliminates the need for additional contour openings, mounting frames, Facilities on the heat dissipation and a special wiring.

The invention is set out below on the basis of the conception
