ABSTRACT:
An inductive transducer having an electromagnetic inductive pickup coil in flux linking relationship to a rotary electromagnetic armature provides spaced output pulses to control current flow, and subsequent interruption of current through an ignition coil; to automatically increase the time during which current can flow through the coil, and change ignition timing, an impedance load circuit is connected to the inductive transducer through a control switch, so that the output characteristic of the inductive transducer is changed when the control switch is operated; the control switch may be speed dependent, or automatically speed dependent by the inclusion of a Zener diode which becomes conductive when the output voltage from the transducer rises, for example as speed of the engine, and hence of the transducer increases.
