Abstract

1282824 Ignition systems ROBERT BOSCH GmbH 10 July 1970 [12 July 1969] 33511/70 Heading F1B An ignition system for an internal-combustion engine has a D.C. circuit containing an inductive impedance 13 and a transistorized switching device for repeatedly breaking the D.C. circuit, the transistorized switching device containing several transistors T1 T2 inter-connected to form a Darlington circuit, one of the transistors T1 having its emitter-collector path in the D.C. circuit in series with the inductive impedance. The transistors inter-connected in the Darlington circuit may be part of an integrated circuit component which is mounted on the ignition-distributer 18. A modification comprising a condenser discharge ignition system is described.
