Nash, P R

A capacitive discharge magneto ignition system is described comprising at least one ignition coil comprising a primary winding and a secondary winding; a magneto comprising: first means for generating a first induced voltage signal; second means for generating a second induced voltage signal having a phase which varies relative to the first induced voltage in proportion to the speed of the engine; and third means for generating a third induced voltage of polarity opposite to the polarity of the first induced voltage signal; a circuit connecting the magneto to the ignition coil for generating a spark in response to the induced voltages and including a charge capacitor charged by the third means and timing means responsive to the first and second induced voltage signals for advancing the timing of the discharging of the capacitor at a predetermined speed through the ignition coil to provide an ignition spark.
