摘要： An improvement in a capacitive discharge ignition system utilizing a permanent magnet assembly (54) revolving in synchronism with the operation of an internal combustion engine to generate spark energy. The relatively high voltage necessary to initiate an ignition spark in a step-up transformer secondary coil (98) is produced by application of a capacitive discharge current to the primary coil (96) of the step-up transformer (100). The ignition spark is initiated in timed relationship when a voltage induced on the secondary coil (98) of the step-up transformer by the passing of the rotating magnet assembly exceeds a characteristic spark-sustaining potential. Longer spark duration at lower engine speeds is provided by configuring the discharge circuit such that only a negligible current flows in the charge coil (104) during the time that the sustaining potential is being utilized to maintain the spark (102). In some exemplary embodiments, the discharge voltage may be triggered by a voltage divider network electrically connected across the primary coil.
