Abstract: A magneto ignition system having inherent means for providing operating biases for components thereof at temperature extremes is disclosed. The disclosed ignition system includes an ignition coil (10) having primary and secondary coil (12, 14) a solid state or semiconductor switch (24) being connected across the primary coil (12) for switching the current therein, and drive and trigger coils (20, 34).

The sensing coil carrier (28) is pivotably mounted to a shaft (22) of the ignition controller (20), and holds a sensing coil (30) a fixed radial distance from the shaft. A trigger rotor (26) having a generally circular configuration with two circumferential walls (90, 92) forming a groove, with a metallic channel member (96) embedded in the groove, is fixed to the shaft (22), so that the sensing coil carrier (28) and the trigger rotor (26) are both referenced to the same axis. The mechanical advance mechanism (24) uses identical springs (60) for primary advance, and a self centering spring (66) for secondary advance, thereby eliminating unbalanced loading that results in hysteresis in ignition advance.

Abstract: A speed limiting system particularly suited for use with magneto ignition systems for small internal combustion engines is disclosed. A shorting transistor (38) is made conductive for a predetermined time after a first trigger pulse from a trigger coil (12), thus preventing subsequent trigger pulses from being effective above a predetermined engine speed.

A diode (42), which also serves to prevent the capacitor (44) from discharging through the trigger coil (12), provides for normal ignition system operation by delaying operating of the shorting transistor (38) until a trigger pulse has become effective upon the gate (34) of a SCR (30).
