摘要： An electronic governor, particularly for a diesel engine has a summing amplifier receiving signals representing the output of the pumps supplying fuel to the engine, engine speed, and engine demand. The summing amplifier serves to produce an output for operating the pump in accordance with predetermined engine current characteristics. A second summing amplifier may be used to override the first summing amplifier to limit maximum fuel. Alternatively, the first summing amplifier may compare demanded fuel supply with actual fuel supply, in which case the second amplifier sets the maximum speed.

摘要： A fuel system for an engine, particularly a compression-ignition engine, has a pump supplying fuel to the engine and a control member for determining the output of the pump, the control member being itself controlled by a control circuit receiving parameters one of which is measured by transducer means. The transducer means is designed so that if it fails, the fuel system fails safe. In another arrangement, in which failure of the transducer means results in an output which would increase fuel, then the failure is detected and action is taken.

摘要： A control system for a vehicle having an engine and a gear box includes an electronic fuel control system for controlling the fuel supplied to the engine by means of a pump. The selection of a particular ratio of the gear box is effected by a control circuit which senses the speed of the vehicle by means of a sensor. When a change in gear ratio is effected, the control system for the gear box provides a signal to the electronic fuel control system which produces a reduction in the amount of fuel supplied to the engine during the gear changing process.

摘要： A fuel injection system for a compression ignition engine includes pulse length control means which determines the instant and duration of opening of a series of injector valves in accordance with the output of a digital memory unit, empirically programmed to match the specific engine. The memory is addressed by two inputs, one derived from an engine speed transducer and the other derived by combining analogue signals from the speed transducer and from a demand transducer. The system operates without any feedback representing the quantity of fuel injected so that no fuel flow transducers are required.

摘要： A fuel system for an engine has a first summing amplifier to which are fed signals representing demanded and actual values of the output of a pump supplying fuel to the engine, together with a signal representing engine speed. The summing amplifier compares the signals it receives and produces an output controlling the output of the pump, and there is also a second summing amplifier to which are fed electrical signals representing engine speed and a reference, a discriminator coupling the two summing amplifiers to a means for controlling the pump, so that the output from the discriminator at any instant is the output from the amplifier demanding the least fuel.

摘要： A fuel system for an engine has a pump which supplies fuel to the engine and an actuator for controlling the pump output. The actuator is controlled by a control circuit to which are fed electrical signals representing demanded engine speed, actual engine speed and pump output. The control circuit sets the slope of the pump output versus speed curves of the engine, and speed-sensitive means operates below a predetermined engine speed for modifying this slope to make it shallower and so produce a smaller change in pump output for a given change in speed.
