ABSTRACT:
An electric governor for electrically controlling the fuel injection amount of a fuel injection pump has two engine speed detectors for producing engine speed indication signals. One of the two detectors produces the signal by using a gear coupled to the pump drive shaft and electromagnetic pickup, and the other of the detectors produces the signal by an output signal of an alternator. Normally the engine speed indication signal is selected from the electromagnetic pickup and used for control of the fuel injection amount, and the output signal of the alternator is used when the electromagnetic pickup generates does not generate the normal output signal.
