Abstract
To provide a sharply rising flank of the ignition pulse, an insert of ferromagnetic material is placed between the primary and secondary coils of the primary and secondary windings of the ignition coil, forming a magnetic shunt to the core, and modifying the wave form of the output pulse from the ignition coil upon sudden interruption of current flow therethrough.
