Abstract
An electronically controlled, hydraulically actuated precision governor controls the operating RPM of an internal combustion engine by repositioning the engine throttle in response to changes in engine RPM. The piston of a hydraulic actuator is coupled to the throttle. The flow of hydraulic fluid to the actuator is controlled by a specially designed hydraulic valve which includes a piston the displacement of which is regulated by controlling the pressure in a pressurized control chamber. The fluid pressure in the pressurized control chamber is regulated by a pair of electronically controlled fuel injector nozzles. The electronic circuitry which controls the two electronic fuel injector nozzles receives electronic inputs corresponding to the operating RPM of the engine, the desired engine operating RPM and engine throttle position.
