ABSTRACT:
The present invention discloses an ignition system for internal combustion engines. The ignition system is particularly applicable to such engines including a magneto.
The ignition system includes a semi-conductor ignition circuit in which a first transistor has its collector-emitter conduction path connected in series with the primary winding of an ignition coil assembly. A resistor is connected between base and collector of the first transistor to permit it to conduct. A control circuit connected between the base of the first transistor and the primary winding, turns the first trnasistor off when it is desired to interrupt the primary winding current.
The ignition system also includes a magneto ignition coil assembly which has a low inductance primary winding having a relatively low number of turns. The coil assemblies of the present invention are generally unsuitable for use with conventional mechanical breaker points.
