ABSTRACT:
A capacitor discharge ignition system is provided with an improved control circuit to achieve predetermined ignition timing characteristics over the range of engine speed operation. In one arrangement the improved control circuit provides engine speed control by introducing a relatively abrupt or stepped ignition timing retard characteristic when a predetermined engine speed is exceeded. If the engine speed increases above the predetermined speed at which the ignition retard characteristic is introduced, additional retarding of the ignition timing is provided. In another arrangement, the control circuit provides an abrupt or stepped ignition timing advance characteristic when a predetermined ignition speed is exceeded. In yet another arrangement, the control circuit first provides the stepped advance as a first predetermined speed is exceeded and then provides a retard characteristic as a second predetermined speed is exceeded greater than the first predetermined speed. The capacitor discharge ignition system is positioned adjacent a rotating permanent magnet that is rotated over a path in synchronism with the operation of an engine to be controlled. The capacitor discharge ignition system includes a core having disposed thereon an ignition coil and a control coil. The control circuit in a specific embodiment of the first arrangement includes a varistor and a capacitor which are selected in the first arrangement to provide the desired retard characteristics to the ignition timing.
