Abstract: A device which serves to activate an adjusting member in dependence on load, in which especially the cross section and/or the pressure differential of an exhaust gas return line which is provided in the intake manifold of an internal combustion engine can be altered in dependence on the load. A fuel injection pump of a known construction is associated with the internal combustion engine, and includes a rate adjusting element, the position of which serves as the control value for the load. This control value, together with a subsequently arranged amplifier device for the control value, produces an adjusting value for the activation of the adjusting element.

Abstract: A fuel control system for an internal combustion engine with correction for optimum values based on a variety of factors. Characteristic engine data is stored in preferably digital memories with capabilities for interpolation. Upon addressing the engine data fields with input signals related to current operational variables, for example the accelerator pedal position, the control system derives therefrom a nominal air flow rate which is used as the reference value in a control loop that sets the amount of recycled exhaust gas and the fresh air flow. As the actual air flow rate approaches the reference value, the fuel flow is adjusted to insure correct mixtures at all times. In another embodiment, the fuel is supplied on demand but cannot exceed a maximum value except under special override conditions. Several other embodiments and variants are presented.

Abstract: What follows is a description of various exemplary embodiments of a fuel injection system for an internal combustion engine with exhaust gas recycling controlled by a throttle valve situated in the suction tube of the system. The throttle valve is in turn controlled by a servomotor having a displaceable piston connected to the throttle valve. The piston is displaceable against a variable restoring force exerted against it and produces displacements of the throttle valve between two positions, one corresponding to a fully opened position of the throttle valve and closed exhaust gas recycling line, and the other corresponding to a substantially closed throttle valve.
