PURPOSE:To make the device in small size and light in weight and also facilitate designing the device with compound integrated circuit, by incorporating into the ignition device two capacitors, i.e. one as bius capacitor and the other to generate signals for a certain specific period of time. CONSTITUTION:This device includes two signal generator circuits one is an ON period signal generator circuit 50 to generate an ON period signal upon comparing the AC signal from a signaling device 1, which emits AC signals in synchronization with the revolutions of an internal-combustion engine, with a specific reference voltage (30), and the other is a time signal generator circuit 80 to generate signals for indication of a certain specific period of time, in synchronization with the former named signaling, and also signals for indication of the difference of the duration between the ON period signal and this specific period signal. The current changing according to change of the AC power voltage shall allow repetition between charge and discharge by means of synchronization of a specific period bius capacitor 12 with revolutions of the engine. A pair of bius circuits 10, 60 to deviate the correlation of the AC signal to the reference signal, as mentioned above, are furnished to provide control of an ignition coil in the ignitor circuit through the use of ON period signals given by the above- mentioned signal generator circuit 50. |
