ABSTRACT:
An electrical control system is disclosed for preventing the speed of an engine from exceeding a predetermined value. The control system includes a reversible motor suitably connected to a throttle control of the engine and further includes motor control circuitry connected to receive an input corresponding to the speed of the engine. When the speed of the engine is below the predetermined value, the control circuitry provides for the operation of the motor in one direction. When the speed of the engine exceeds the predetermined value, the control circuitry provides for the reverse operation of the motor actuating the throttle control to limit the engine speed to the predetermined value.
