Abstract
There is disclosed herein an ignition system for engines which includes the usual form of ignition circuit which generates an ignition control signal on the basis of timing pulses. There is further included an inhibition circuit connected with the ignition control circuit to inhibit the generation of the spark discharge of a spark plug under certain circumstances, such as in stopping the engine and when the engine RPM is below a predetermined value lower than idle. Furthermore, an embodiment disclosed herein allows improvement of the accuracy of ignition during engine starting.
