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.

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: A fuel injection pump for internal combustion engines, in particular an in-line injection pump for Diesel engines, is proposed having an injection quantity governor and an electrically driven feed pump, in which in order to assure an emergency shutoff in the event of a malfunction of the injection quantity governor, a check valve, the forward flow direction of which is toward a suction chamber filled with fuel by the feed pump, is disposed between the pressure-side outlet of the feed pump and the suction chamber. An emergency shutoff device responding to a malfunction switches off the feed pump drive, so that because of the lack of feed pressure the check valve closes and blocks off the suction chamber. The engine comes to a stop, as soon as a partial vacuum is established in the suction chamber, which occurs as soon as several revolutions later.

Abstract: A fuel injection device for mixture compressing, externally ignited internal combustion engines, which serves to meter the fuel proportional to the intake air and aspirates the air-fuel mixture. The fuel injection device includes an air flow rate meter located downstream of a butterfly valve in the air induction tube. The bearing shaft of the air flow rate meter includes a fuel metering valve which can be activated directly by the air flow rate meter. To correct the air-fuel mixture because of air density downstream of the butterfly valve, the fuel injection device is so arranged, that when the butterfly valve is in its idling and full load positions a rich air-fuel mixture can be regulated, and when the butterfly valve is in a partial load position a lean mixture can be regulated.

Abstract: A regulating device used with the fuel injection system of an internal combustion engine, for regulating the proportions of the operating mixtures of the engine. The regulating device is embodied as a pump which is incorporated into the existing fuel injection system. The pump has a chamber within which a piston is displaceable. This piston is coupled with the fuel rate adjusting member of the fuel injection pump of the fuel injection system, and is displaced in accordance with the adjusted position of the fuel rate adjusting member. The pump is also connected with the throttle plate of the fuel injection system located in the induction tube of the engine. By reason of these connections, rapid adjustment movements of the fuel rate adjusting member can be effectively translated to a proper adjustment of the throttle plate without the delay found in presently known regulating devices.

Abstract: An air flow rate sensor, located in the indication tube of an internal combustion engine, displaces a fuel metering slide, thereby changing the fuel flow and the fuel pressure gradient. This pressure gradient is applied to a differential pressure valve which actuates a fuel flow control throttle until the pressure gradient has been restored to a nominal value, corresponding to a desired fuel-air ratio.In a variant embodiment, an arbitrary change in the metered out fuel results in a fuel pressure gradient which is used to reset an air-flow control member until the nominal value of the pressure gradient has been restored, corresponding to a desired fuel-air ratio.

Abstract: A fuel injection system for an internal combustion engine includes an air flow responsive throttle element in the induction tube which is subject to an adjustable elastic restoring force. The throttle element is attached to a bushing which rotates about a pivotal shaft mounted within the induction tube. A control slot in the bushing is covered to varying extent by a control edge on the pivotal shaft so that fuel which enters a groove in the shaft is metered out according to the relative rotation of shaft and bushing. The relative position of the throttle can be adjusted by a pressure cell.
