ABSTRACT:
An ignition apparatus wherein an AC current signal is produced from the coil of a pick-up in accordance with the engine revolutions and the primary-side current of the ignition coils is regulated in accordance with the output signal from the pick-up coil thereby to generate a high voltage at the secondary side of the ignition coils. Further, a monostable multivibrator and means for generating a voltage corresponding to the output frequency of the pick-up coil are provided in order to maintain the duration of energization of the primary side of the ignition coils substantially constant over a wide range of variations of engine revolutions from low to high levels. The monostable multivibrator is so connected that the output width thereof which is controlled by the output of the voltage generator means is long in low engine revolutions and short in high engine revolutions, that the output is produced upon completion of ignition, and that the primary-side current of the ignition coils begins to flow at the end of the output of the monostable multivibrator which is determined by the output of the pick-up or that of the monostable multivibrator, whichever is produced earlier.
