THYRISTOR IGNITION SYSTEM Russian patent published in 1995 - IPC

FIELD: electrical equipment of gasoline engine, in particular electronic ignition system with storage capacitor. SUBSTANCE: ignition system has inductance storage unit 1, power transistor 2, regulating unit 4, spark transformer 15, storage capacitor 13. Novelty is that lead of second secondary winding of storage unit 1 is connected via series-connected additional capacitor and second resistor to common wire of system; if third transistor is connected in base circuit of second transistor, additional diode is inserted between base and emitter of third transistor; novelty is also that time constant of mentioned circuit set up of series-connected capacitor and second resistor is 0.1 to 0.5 of pulse duration of conducting power transistor. EFFECT: improved reliability of system and its efficiency. 2 cl, 2 dwg
