IGNITION SYSTEM Russian patent published in 2002 - IPC

FIELD: capacitor ignition systems at continuous pulse accumulation of energy for internal combustion engine; transport facilities and power plants with any ignition coils. SUBSTANCE: proposed system includes DC converter, two energy storage capacitors, choke, electronic switch with signal and control inputs and one output, ignition coil, electronic switch control unit with two inputs (signal and control inputs) and two outputs, unit for turning-on electronic switch with two inputs and one double-pole output and capacitor. Electronic switch control unit includes two univibrators, 2 OR, 2NAND and NOT gates; output of 2NAND gate is first output of electronic switch control unit and output of not gate is its second output. Electronic switch of ignition system employs thyristor. EFFECT: enhanced reliability due to enhanced noise immunity of electronic switch control unit. 3 cl, 2 dwg
