Abstract
1480264 Ignition systems ROBERT BOSCH GmbH 30 Oct 1974 [30 Oct 1973] 46906/74 Heading F1B In an ignition system comprising a switching transistor 10 and a control transistor 14 a shunt branch of a circuit breaker 19 contains a switching member 20 having a fixed breakdown voltage and the base emitter path of the control transistor 14 and this shunt branch together with a control resistor 21 is in parallel with the series combination of the switching transistor 10 and the primary winding 8 of an ignition coil 7. In a modification (not shown) the Zener diode 34 is connected between the resistor 30 and the line 26 and a further diode and a resistor are added.
