ABSTRACT:
A governor control system for an internal combustion engine of the type wherein the operator's fuel command signals are furnished to a computer which controls the amount of fuel flow to the engine and calculates the amount of airflow necessary to provide a perdetermined air/fuel ratio in a fuel-air section. The computer includes a second section for receiving engine status signals relative to actual engine operating conditions and utilizing them to provide an output equivalent to a related maximum allowable engine speed. A third or governor control section in the computer compares output from the second section and also a signal related to the present actual engine speed to produce an error signal which is utilized to produce a fuel rate signal commensurate with the maximum allowable engine speed. A selector compares the fuel rate signal and the operator's fuel command signal to produce a modified fuel command signal to the fuel-air control section of the computer which will not cause the engine to exceed its predetermined maximum allowable limit.
