ABSTRACT:
An electrically controlled fuel injection pump for an internal combustion engine includes a fuel distributing piston, a collar cooperating with the fuel distributing piston to determine the amount of fuel injected into the engine, and an electromagnet having a rotary armature connected to the collar for driving the same. A signal generator is engaged to the rotary armature for sensing the angular position of the rotary armature. A transducer is provided for sensing the power output required of the engine. A control circuit is connected to the signal generator and the transducer for receiving the output signals thereof, and is also connected to the electromagnet for driving the same according to the output signals of the signal generator and the transducer. The control circuit drives the electromagnet, therefore, by means of feedback control so as to control the amount of fuel injected into the engine in response to the power output required of the engine. A damper is connected to the rotary armature for providing resistance to the movement of the rotary armature. The damper can act to limit the rates of both increase and decrease of fuel supply or just the rate of decrease of fuel supply.
