ABSTRACT:
The AC signal generator furnishing the basic control signal for ignition timing is a Hall generator the flux through which is gradually increased while the crankshaft of the engine rotates through a predetermined angle of rotation. The Hall generator is part of a magnetic circuit which also includes an air gap. The change in flux is accomplished by rotating a tapered magnetically conductive member through the air gap. The output of the Hall generator is applied through a linear amplifier to a threshold circuit whose output controls an electronic interrupter switch connected in series with the ignition coil.
