摘要： A fuel injection system for externally ignited engines employing continuous manifold injection includes a fuel metering valve assembly. The control slide of this valve assembly is actuated by the air-flow through the induction manifold and controls the size of fuel flow apertures. A differential pressure valve normally maintains a constant pressure difference across these metering valve apertures. The magnitude of this normally constant pressure difference can be altered in response to signals obtained from or measurements performed on operational parameters of the engine; for example, the oxygen content of the engine's exhaust gases.

摘要： A device is proposed for drift compensation in fuel metering systems, in which it is not the metered quantity as such which is controlled in closed-loop fashion, but rather only the position of a quantity-determining member. The object of the invention is to maintain or re-obtain the original association between the fuel quantity and the position signal of the quantity-determining member for the purpose of providing a correct indication of the load state existing at a particular time. The drift compensation is intended to be capable of being performed manually, semi-automatically, or automatically, in an additive and/or multiplicative manner. It can furthermore be realized via a preferably rpm-dependent characteristic curve. The various values may be ascertained, for instance, in connection with running-out and running-up tests.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
