Abstract
A capacitor ignition system of magnet type comprises a charging winding (10), a trigger winding (11), an ignition coil (13) and an ignition switch (14) with electronic control means, in this case a micro-processor (16). For practical, economical reasons the voltage of the charging winding cannot be used for current supply to the electronic control means as this voltage is several hundred volts. In the trigger winding the chosen voltage can be a few volts which is a proper voltage for the control means. The trigger winding of the invention has double functions: to generate a reference voltage for spark release (triggering) and to be an energy source for the electronic control means.
