    Abstract: A fuel injection system for externally ignited internal combustion engines in which a fuel metering and distributing valve is controlled by an air sensing element disposed in the air suction tube of the engine and by structure which is adapted to alter the restoring force exerted on the air sensing element through the fuel metering and distributing valve. The noted structure includes a control pressure conduit, a pressure control valve connected to the control pressure conduit and further conduits for connecting the pressure control valve to the suction tube of the engine downstream of the butterfly valve and between the air sensing element and the butterfly valve. With this structure it is possible to alter the restoring force mentioned above so that a properly proportioned fuel - air mixture is achieved for various load changes of the internal combustion engine.

    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.

The noted structure includes a control pressure conduit, a pressure control valve connected to the control pressure conduit and a further conduit for connecting the pressure control valve to the suction tube of the engine downstream of the butterfly valve. With this structure it is possible to alter the restoring force mentioned above so that a momentarily enriched fuel-air mixture is achieved when the butterfly valve is suddenly opened and so that a momentarily weakened fuel-air mixture is achieved when the butterfly valve is suddenly closed.

    Abstract: A fuel injection pump for internal combustion engines having a hydraulic control mechanism includes a control cylinder with a control piston actuating a control member, a hydraulic work chamber and one switching valve each for an input and an output controlled by a valve control unit. The inflow to and return from the work chamber is provided with the control valves in order to shut down the engine upon a shutoff or a malfunction in the hydraulic control mechanism. The fuel feed pump is electrically driven, and the hydraulic work chamber communicates with the fuel tank via a relief device. The supply of current to the valve control unit and the feed pump is switched on and off, along with the rest of the current supply to the engine, via a driving switch. Additionally, the valve control unit is embodied such that upon the appearance of a persistent control deviation of the control member, the valve control unit shuts off the feed pump. The relief device includes various variant embodiments operative upon shutoff of the current supply or the occurrence of a malfunction and enables the restoration of the control mechanism to its zero or stopping position.

    Abstract: A nozzle holder for internal combustion engines is proposed, in which a sleeve can be secured in the cylinder head by means of a tightening nut. The sleeve protects the portion of the nozzle which protrudes into the combustion chamber from thermal effects. Ease of serviceability is attained in that when the nozzle holder is rotated out of the cylinder head, the sleeve is simultaneously removed, without requiring additional hand operations.

    Abstract: The invention is directed to a safety arrangement for an internal combustion engine having self-ignition where, in the sense of an overall system monitoring, specific signals relating to the operating conditions of the internal combustion engine are continuously monitored. These signals are indicative, for example, of the position of the throttle pedal, the computed rack-travel nominal or desired value, and the rotational speed. The monitored signals are processed and a corrected rack-travel nominal value is generated by means of a minimum-value selection circuit. The corrected rack-travel nominal value signal generated in this manner is fed to the rack controller of an EDC unit. At the same time, a deviation in rack travel is determined utilizing the corrected rack travel nominal value in combination with an actual-value signal of the rack travel fed back from the rack-travel sensor. The signal indicative of actual rack travel also serves for a comparison with the upper and lower limits of the rack-travel sensor voltage; and, depending on the error condition occurring, either the output stage of the rack controller is de-energized and/or the fuel-injection pump is simultaneously shut off by means of an electrical shutoff valve (ELAB); or, a decision for an emergency operation is made.
