ABSTRACT:
The present invention discloses a multiple spark transistor ignition circuit which is able to provide negligible retardation of ignition time, and/or prevent ignition with reverse rotation and/or provide an additional advanced spark and/or govern maximum engine speed and/or progressively advance the moment of ignition with increasing engine speed. The basic circuit comprises an ignition circuit of the type disclosed in U.S. Pat. No. 4,163,437 (Notaras) with a diode interposed between the primary winding and the remainder of the circuit. Circuits having a single primary winding and dual remainders or dual primary windings and single remainders are also disclosed. A governor circuit having a control transistor, a further potential divider and a control capacitor, is also disclosed.
