Abstract
An ignition system for an internal combustion engine having a flywheel coupled to a plurality of bipolar magnets and a camshaft coupled to a unipolar magnet. A bipolar Hall sensor is positioned adjacent the flywheel for detecting passage of the bipolar magnets and generating a square wave signal to provide camshaft position. A unipolar Hall sensor is positioned adjacent the camshaft for detecting the passage of the unipolar magnet and generating a square wave signal to provide a reference signal indicating a known position of one cylinder.
