ABSTRACT:
There is proposed an ignition apparatus for use with an internal combustion engine, including therein an ac or dc power source and an ignition coil whose primary winding together with a controllable electric switching element forms a closed circuit. The apparatus includes therein a control circuit for controlling the electric switching element, which control circuit comprising a first, second, and third signal generating means for supplying control signals to the control electrodes of the switching element in synchronism with the ignition timing of the engine. The third signal generating means detects the spark positions, i.e. angular positions of the engine shaft at which the spark plugs are to be fired, at high speeds of the engine so that the maximum advance in angular position for ignition timing can be suppressed.
