    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 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: The invention is directed to an arrangement for controlling the engine speed and especially the idle engine speed of an engine of a motor vehicle. The pregiven idle engine speed desired value is controlled in dependence upon the road speed of the motor vehicle so that this desired value becomes greater with increasing road speed.

    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: 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: An apparatus to control the composition of the operating mixture of an internal combustion engine in which the fuel is apportioned by means of a variable cross-sectional apportionment area where the pressure drop is kept constant by a differential pressure valve. The uncontrolled pressure chamber (reference pressure chamber) of the differential pressure valve lies downstream of an apportioning recessed area. A given fuel discharge quantity from the controlled pressure chamber of the differential pressure valve is determined in accordance with the fluctuations of the pressure in the reference pressure chamber, and a positioning motor provided for the correction of the magnitude effecting the deviation of the reference pressure is further actuated in accordance with the discharge quantity. The controlled pressure chamber lies upstream of the apportioning recessed area within a fuel supply line connected to a fuel feed pump, and a storage chamber having a wall displaceable against a restoring force as well as a pressure control valve that is connected to the fuel supply line.

    Abstract: An air flow rate sensor, located in the induction 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 stratified-charge engines includes a fuel metering valve assembly controlled by an air flow sensor. The restoring force on the movable plunger in the fuel metering assembly may be varied in dependence on load by a differential pressure valve whose bias is changed by a cam-follower which cooperates with a gas-pedal linked cam. The system may also include a throttle bypass also controlled by a cam. The system may further include separate fuel injection valves for each main combustion chamber, fed by a fuel distributor mechanism.

    Abstract: A fuel injection system for mixture-compressing, externally ignited internal combustion engines of the type employing continuous fuel injection with an induction tube. A measuring member, as well as an arbitrarily actuatable throttle butterfly valve are disposed in sequence within the induction tube. A fuel metering and quantity distribution valve assembly is controlled by the measuring member in proportion to air flow rate. Pressurized fluid, preferably fuel, provides a restoring force for the measuring member, via a control pressure circuit. At least one pressure control valve is provided for controlling the pressure in the control circuit in dependence on motor parameters. A heatable control element, operating in dependence on temperature, forms part of the control valve. The heatable control element, which may be a bimetallic spring, acts in opposition to the force of another spring. Instrumentalities are provided for reducing the pressure of the pressurized fluid in the control pressure circuit during the warm-up phase when the engine is suddenly accelerated.
