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.

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.
