ABSTRACT:
A regulating servo loop for controlling the speed of an internal combustion engine to a preselected rate, including a tachometer connected for rotation of the output of the engine, a mechanical actuator controlling the carburetor opening of the engine and a resonating error circuit for detecting the error between the preselected rate and the tachometer output. The mechanical actuator includes a D.C. servo motor which is driven in the correcting direction by a transistor circuit according to the phase lag of the resonating circuit.
