Abstract
An improved crankshaft trigger wheel for use in an ignition system for an internal combustion engine. The configuration of the trigger wheel provides a high degree of electrical noise immunity, provides a single piece construction which has the dual function of a trigger wheel as well as an engine harmonic balancer. The wheel is made into a configuration which is easily shaped during manufacture, and provides a wheel shape which produces a higher degree of timing accuracy. The wheel of the present invention has an outer, circumferentially extending surface interrupted by corners, with the corners being defined by two adjacent arcs, wherein each arc has a radius which is greater than the radius of a circle described by the rotating wheel.
