FIELD: mechanical engineering; ignition systems. SUBSTANCE: device has input signal pickup and series- connected voltage converter, storage device, switching device and ignition coil, ignition control signal unit connected by its output to switching device input, input signal matching circuit connected between input signal pickup and ignition control signal shaping unit, oscillatory circuit through which storage device is recharged by ignition coil self-induction current and desired wavelength maintenance circuit. It has also output voltage stabilization circuit and circuit for stabilizing starting at ambient temperatures within -60 C and +125 C coupled with voltage converter. Desired wavelength maintenance circuit is placed between storage device and input of ignition control signal shaping unit. EFFECT: enhanced stability of spark discharge energy and reliability of sparking. 1 cl, 1 dwg
