Abstract: An apparatus for fixing the composition of the gas content and the degree of filling of cylinders in an internal combustion engine having autoignition, including a fuel metering device to which a signal dependent at least on the position of the driving pedal can be delivered and having an exhaust gas feedback control element in the air intake line as well as an apparatus for controlling the exhaust feedback rate. The apparatus includes measurement value transducers for the at least indirectly detectable total cylinder filling and the ratio of fresh air to exhaust gas or the air ratio pertaining to the aspirated fresh air and/or the fuel metering is influenced among others in accordance with this measurement value. The detection of the total cylinder filling can be accomplished indirectly by using measurement techniques for detecting pressure and temperature in the intake manifold. Besides using pressure transducers, whose output signal may be corrected in accordance with temperature, if desired, it is also possible to use an arrangement for measurement of the total gas quantity between the exhaust feedback point and the inlet valves. The object of the proposed apparatus is to set the mixture of fresh air and exhaust gas which is optimal at any given time with respect to toxic substances in the exhaust, by means of processing as many observable influencing factors as possible, and in particular by processing the total cylinder filling, which is of significance especially in terms of the limitation of solids in the exhaust which is expected to be made a legal requirement. Alternatively, the signal for the total cylinder filling can be used in order to adjust a suitably controllable supercharger via a governor in such a manner that the total cylinder filling (charge quantity) is constantly controlled. Thus, under altered environmental conditions, the optimal air ratio for normal conditions pertaining to the aspirated fresh air can be maintained with respect to toxic substances in the exhaust.

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: The fuel mixture of an engine is controlled by a mechanism responsive to the signals from an oxygen sensor located in the exhaust pipe. The oxygen sensor is provided with a heater to permit rapid attainment of normal operating temperatures. The heater is controlled by a switch actuated by a timing circuit. The timing circuit closes the switch whenever the alternating signals from a comparator responsive to sensor signals do not occur, indicating sensor non-operation.

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.
