  • Fuel pumping apparatus with timing correction means
    Patent number: 4033310
    Abstract: A fuel pumping apparatus comprises an injection pump including a cam angularly movable to vary the timing of injection of fuel, the cam being operated by a servo-mechanism which is controlled by an electrical torque motor. The supply of electrical energy to the torque motor is controlled by a control circuit which receives signals indicative of the speed of and the load on the engine, and also a signal from a transducer indicative of the actual timing of injection of fuel to the engine and also a signal from a transducer indicating the position of the parts of the engine. The control circuit processes the signals to provide for variation in the timing of injection of fuel in accordance with the speed and the load, and also checks that the actual instant of injection is correct.
