Abstract
An ignition system for an internal combustion engine. The system is a type that employs a continuous-wave oscillator which includes a transformer with a high voltage output winding to supply the sparking circuit via a distributor. And, the transformer has an oscillator control winding for starting and stopping oscillation. There is an electronic switch to control application of a DC bias current to the control winding when the oscillator is not oscillating. And, the improvement concerns using plural crank angle controlled sensors with electronic circuit means to select a desired one of the sensors to provide the crank angle degree ignition timing desired.
