Abstract: In a fuel metering device for an externally ignited internal combustion engine with compression of the air-fuel mixture, which system comprises a suction tube for the intake of air in which an air-measuring device and a randomly adjustable throttle valve having a flap are arranged in sequence, and in which an essentially proportionate amount of fuel is metered into the amount of air flowing therethrough, and wherein the proportionality of the fuel amount is adjustable by means of controlling a bypass circumventing the air-measuring device in dependence on engine data, there is described an improvement which comprises a valve arranged in the bypass, the said valve being controllable by the pressure prevailing in the suction tube in the vicinity of the throttle valve, a pneumatically actuated valve means adapted for controlling the valve in the bypass, and conduit means connecting the pneumatically actuated valve means with the suction tube and having an orifice in the latter which orifice is located upstream of the throttle valve, taken in the direction of air flow through the suction tube, and also upstream of the part of the flap of the throttle valve moving against the flow of air during the release of the air supply, yet still in the immediate vicinity of the said flap part.

Abstract: In a diesel internal combustion engine comprising an air intake pipe and a throttle valve arranged in the latter, the throttle valve is equipped with a drive in order to prevent operating states which are dangerous for the internal combustion engine, e.g. uncontrolled exceeding of the allowable maximum speed due to disturbances. The drive holds the throttle valve open during trouble-free operation and moves it into a closed position during disturbances. The closed position of the throttle valve is determined in such a way that the remaining reduced air flow cross-section throttles the combustion air passing through to such an extent that the internal combustion engine still runs securely at idling speed and does not exceed a predetermined speed during feeding of a desired quantity of fuel.

Abstract: A fuel injection pump of the distributor type in which to attain low injection rates in the idling range, longitudinal slits or longitudinal conduits are provided in the jacket face of the pump piston in accordance with the number of supply strokes of the pump piston. The slits or conduits are in continuous communication with an annular groove and the adjoining annular slide which is the quantity adjusting device of the fuel injection pump. The slits on conduits come in turn into communication with a control opening during the supply stroke of the pump piston via which opening the pump work chamber can be relieved whenever in the course of the pump piston stroke movement a second outlet opening of a relief conduit extending in the pump piston and communicating with the pump work chamber, comes into communication with the annular groove. From this point on, in order to attain quiet idling of the engine, the supply rate of the pump piston is reduced by the outflow rate, determined by a throttle of the pumped fuel into the suction chamber. By rotating the annular slide relative to the pump piston, the control opening can be moved out of the operating range of the longitudinal conduits and the quiet-idle device is shut off.

Abstract: An electronic control device is proposed for manipulated variables of an internal combustion engine having self-ignition. In this device, an injection duration signal is utilized as a load signal. While the injection onset signal can be satisfactorily detected via the opening speed, the hysteresis signal is efficaciously utilized to detect the signal for the end of injection. The proposed solution makes it possible to detect and regulate both the injection onset and the fuel quantity, using only a single transducer in the injection valve, on or in the fuel line, or on the pumping element, and this load signal is available for generalized uses in the control device. It is furthermore possible to obtain an rpm signal on the basis of the signal for injection onset and/or end, and to process it further.

Abstract: An automatic control for an adjustable turbosupercharger in the air supply of an internal combustion engine adds a static anticipatory control signal and a dynamic anticipatory control signal to the error signal that is provided to an actuating mechanism for the control of the supercharger. The error signal is obtained by comparing actual charging pressure with a reference charging pressure for one portion of the control displacement and in the other portion of the control displacement the error signal is obtained by comparing actual air quantity supplied to an engine cylinder with a reference air quantity. This results from a limiting device interposed in the charging pressure control loop. The static anticipatory control depends on engine speed and engine load and is supplied with additive corrections for engine temperature and for battery voltage. A limit value dependent upon engine speed is introduced through a minimum circuit to put a lower limit on the sum of error signal and static anticipatory control and the resulting signal is then added to a dynamic anticipatory control and derived from rate of control displacement. The control signal is also interrupted during the engine start period.

Abstract: A control device for internal combustion engines, especially for turbocharged diesel engines. The control device is arranged to generate a control distance proportional to the amount of air supplied to the engine. The control device includes a pressure chamber charged by the intake air pressure, which is separated from the back-pressure chamber by a membrane. A stop abuts against the membrane and is scanned via an intermediate lever by a supply volume adjustment element of a fuel pump. The reference absolute pressure in the back-pressure chamber is positioned between a throttle with variable throttle diameter and a throttle with fixed throttle diameter. A vacuum pump aspirates air via the throttle with fixed throttle diameter, connected to atmospheric pressure, and the throttle with variable throttle diameter is arranged to respond to the reference absolute pressure.

Abstract: An apparatus is proposed which serves the purpose of load-dependent actuation of an adjustment device, wherein the cross section and/or the pressure drop of an exhaust recirculation line in an internal combustion engine can be varied in accordance with load. An injection pump of conventional design is associated with the internal combustion engine and further includes a quantity adjustment device, the position of which acts as a control variable for the load. With this control variable, a booster apparatus is controlled via a comparison apparatus; the output variable of the booster apparatus in turn is the control variable for the actuation of an adjustment device which acts on an exhaust recirculation control apparatus. When a threshold value for load is exceeded, the exhaust recirculation is precluded. The control variable is preferably formed as a fuel pressure signal with the fuel withdrawn from the suction chamber of the injection pump. Apparatuses are proposed by means of which, in the event of the actuation of the control apparatus for exhaust recirculation, the smallest possible removal quantity of fuel is required for control purposes.

Abstract: A fuel injection pump for internal combustion engines is proposed in which cavitation is avoided at the sealing surface between a threaded connection element which contains the pressure valve and a securing flange of the pressure valve housing which protrudes radially outwardly therefrom. The securing flange is attached to a cylindrical portion on the end of the valve housing remote from the pressure line leading to the injection nozzle and a sealing member is fitted into an intermediate chamber between the cylindrical portion and an inner wall of the threaded connection element. This sealing member is pressed with at least one annular contact surface onto the cylindrical housing portion and with a different contact surface, axially displaced with respect to the first, is pressed against the threaded connection element. The sealing member may be embodied as a thin-walled sheet-metal sleeve, may comprise a spiral spring, or may be made of plastic.
