    Abstract: A fuel injection system employing continuous injection into the induction manifold for varying the fuel-air ratio during the warm-up phase of the engine. A pivoting flap responds to the air flow through the induction tube and rotates a metering valve core. Openings in this valve core cooperate with openings in the valve cylinder to form a metering valve aperture of variable cross-section. The pressure differential across this aperture influences the metered fuel quantity and this pressure differential can be varied during the warm-up phase of the engine. The variation in the pressure differential is accomplished by heating a bi-metallic spring which disengages from the closure element of a diaphragm valve, increasing the closing bias thereof. The resulting increase in fuel pressure downstream of the metering aperture displaces a piston which removes the additional biasing force on another diaphragm valve, permitting the reduction of fuel pressure upstream of the metering aperture with the net effect of a reduction of the pressure differential across the metering aperture and a corresponding reduction of the metered fuel quantity, i.e., a leaning out of the fuel-air mixture.

    Abstract: A fuel injection system for externally ignited internal combustion engines including fuel injection nozzles, a fuel distributor unit, a fuel supply circuit, and a control pressure circuit. The distributor unit includes metering valves, pressure valves and a first throttle which separates the fuel supply circuit from the control pressure circuit. At least one of the pressure valves is embodied as a differential pressure control valve which has one chamber connected to the first throttle and the control pressure circuit. The control pressure circuit includes the above-mentioned chamber of the differential pressure control valve, a magnetic valve, a storage element and a second throttle. With the system noted, the pressure difference across the metering valves may be varied by varying the pressure difference across the first throttle by means of the magnetic valve via the storage element and the second throttle.

    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.
