Abstract
An ignition control system for an internal combustion engine, having an on-off device for controlling, at every one operational cycle of the engine, a timing to generate a discharge arc flame in each of the spark plugs to ignite the combustible mixture in such a manner that said timing is advanced just after the engine, in a cold condition, is started, then, delayed and again advanced when the engine is warmed-up. A stable idling operation as well as a low emission of toxic components are obtained.
