FIELD: transport engineering; electronic ignition system.
SUBSTANCE: invention relates to electronic ignition systems with capacitive energy storages. According to invention, multispark electronic ignition is provided by device containing electric breaker contacts, inductance coil, variator, self-excited oscillator built around bipolar transmistor, rectifier energy storage, diode and thyristor switches, thyristor switch control circuit and starting circuit and contact chatter protection circuit. At supply of car system voltage, self-excited oscillator is started and attains self-oscillation mode of operation. Voltage within the limits of 390 V is removed from secondary winding of self-excited oscillator and through rectifier said voltage charges capacitive storage. Diode and thyristor switches provide oscillatory process of discharging of energy storage through primary winding of inductance coil, and spark forming oscillating voltage is obtained at secondary winding.
EFFECT: provision of reliable sparking at changes of supply voltage within wide range, provision of multispark operation owing to multiperiod oscillatory discharge of reservoir capacitor.
