ABSTRACT:
Speed limiting in an ignition system utilizing a magneto generator is accomplished by increasing the damping of the half wave not utilized for ignition. This is accomplished by switching in additional resistance in parallel with the damping circuit resistance when the speed of the engine exceeds the speed to which it is to be limited. The additional damping during the half wave which is not utilized causes a decrease in the current and voltage wave utilized for ignition because of armature reaction. The decrease, in turn, causes a sudden change in ignition timing in the direction of late ignition and therefore an additional damping or complete suppression of ignition.
