ABSTRACT:
This disclosure relates to apparatus for selectively limiting the speed of an internal combustion engine by momentarily removing the ignition voltage to the spark plug of said engine at one or two preselected speeds below the maximum speed capability of the engine. Said speed limits are activated in response to electrical input signals generated by switches controlled by the operating condition of a vehicle driven by said engine. Such electrical signals could be determined by whether the vehicle transmission is in reverse and/or switches selectively operated by the operator. This emitter therefore controls the engine and thus vehicle speeds to increase the safety of the vehicle under selective operating conditions.
