ABSTRACT:
An ignition apparatus for an internal combustion engine, wherein the energization time of the primary winding of the ignition coils is maintained constant regardless of the engine revolutions, is provided with reference time signal generator means within the apparatus. The reference time signal thus produced from the reference time signal generator means is compared with an actual energization time, and the time difference therebetween is negatively fed back to the energization time signal generator means, thereby controlling the energization time in such a way as to always approximate the reference time.
