UNIVERSAL THIRSTER IGNITION SYSTEM FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: system has converter 1, capacitors 2,9,17, switches 3,8, switches 4,14, resistors 5,6,11,18,20, diodes 7, coil 10, and units 12,13. The circuit provide control of switches 3,8 so that capacitor 9 is charged impulsively not after oscillating discharge but during each stroke of recharging under the action of inductive coil 10. The switches are synchronized by a signal from a pickup of coil current made of resistor 11. EFFECT: higher frequency and energy of sparking. 2 dwg
