Description: |
| "A means for readily changing the ignition system of an existing internal combustion engine to a solid state capacitive discharge ignition system which comprises an auxiliary coil, a primary ignition coil and a secondary ignition coil wound on a single leg of a stator. The stator is designed with one or more additional legs which complete a conductive path for the time varying flux, and adapt the stator for mounting on the existing structure of the engine. In addition, two legs of the stator which define a flux path may each be divided into two segments at their outer extremity, one of each pair being slightly longer than the other so as to create two different size air gaps for each leg. A washer-like element may be used in cooperation with the above structure to change the position of the rotor relative to the crankshaft so as to alter the timing of the ignition system." |
