Abstract
A combined ignition control and injection valve operating circuit has an inductor connected in (series or) parallel with the ignition coil so that it carries current whenever an output transistor of an ignition control circuit is on. A thyristor connects the inductor to an energy storage capacitor and turns on each time the transistor turns off to create an ignition spark. The capacitor is thus charged up and the stored energy is discharged through a triac into an injection valve solenoid to speed up current growth in the latter on each energization thereof.
