ABSTRACT:
This invention relates to an ignition system for an internal combustion engine. The ignition system comprises an ignition circuit to generate a spark at an ignition plug in synchronism with a rotation of the internal combustion engine. The ignition circuit may be of a capacitor discharging type or of an ignition primary current interrupting type. The ignition system further comprises an ignition preventing circuit to prevent the ignition circuit from being operated when the internal combustion engine is rotated at a speed of revolution higher than a first set value of r.p.m. and when a throttle valve operating member is quickly returned to a position at which the r.p.m. of the engine is lower than the second set value of r.p.m. which is lower than the first set value of r.p.m. The ignition preventing circuit may be adapted to fully prevent the operation of the ignition circuit. Alternatively, the ignition preventing circuit may be adapted to thin the operation of the ignition circuit.
