ABSTRACT:
An engine speed limiter for an internal combustion engine having an ignition primary winding that outputs an ignition pulse and fires a spark plug in response to the ignition pulse is disclosed. An electrical storage device receives electrical energy from the ignition primary winding. A control circuit receives electrical energy from the electrical storage device and generates a trigger signal. The potential of the received electrical energy of the controller is limited to a predetermined value by the controller. A switching mechanism is responsive to the trigger signal and shorts the ignition pulse, thereby preventing the spark plug from firing.
