    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 properly proportioned fuel-air mixture is achieved, and in particular, so that a properly enriched fuel-air mixture is achieved during full load operation.

    Abstract: A fuel injection system for externally ignited internal combustion engines in which fuel is individually metered to each injection valve through mutually displaceable metering valves. A diaphragm-type pressure valve is disposed between each metering valve and each injection valve. One of these valves is a differential pressure valve, which maintains a constant pressure difference across the metering valve to which it is connected. The remainder of these diaphragm valves are pressure equalizing valves, controlled by the output pressure of the differential pressure valve to maintain the same constant pressure difference across each of the remaining metering valves. The injection valve supplied with fuel by the differential pressure valve, opens at a higher fuel pressure than the remaining injection valves, thus also serving as a pressure valve. Additionally, the pressure setting of the differential pressure valve can be changed, when required, in dependence on a particular engine parameter by other control means.

    Abstract: What follows is a description of a fuel injection system for spark plug-ignited internal combustion engines with compression of the air-fuel mixture and structure for controlling the system pressure. The system is one which includes a device for regulating a fuel injection quantity operating in dependence on the air quantity streaming through a suction tube of the engine, a pressure regulator for determining normal system pressure, injection nozzles which have an opening pressure lower than the system pressure, a continuously delivering fuel pump, and the structure identified above. This structure adjusts the device for regulating the fuel injection quantity so that the starting pressure in the system is retained below the opening pressure of the injection nozzles and above the vapor pressure of the fuel until a quantity of fuel sufficient to replace the quantity of fuel evaporated or leaked due to a temperature gradient in the system resulting from engine cut off has been restored.

    Abstract: 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.

    Abstract: Sensors for motor vehicles emit a base signal when the variable which they measure takes on a base value. For example, a road-speed transducer supplies no pulses when either the vehicle is at standstill or when the sensor is defective. A method for providing a reliable operation of a motor vehicle includes the step of starting a substitute/emergency-function immediately when only the base signal is received from the sensor. If it is later determined that the base signal was only emitted because the measured variable took on its base value, then the substitute/emergency-function is again reversed. By starting a substitute/emergency-function basically always when a checked sensor emits no signal, it is ensured that safety measures are taken as rapidly as possible.

    Abstract: To monitor the functioning of a redundant safety fuel shut off valve in a diesel engine, the electric power supply for a controlling device for the fuel quantity adjustor of a fuel injection pipe is decoupled from the power supply for the control of the electromagnetic fuel shut off valve. A relay controlled by a driving switch of the engine has a contact whose opening is time delayed relative to the opening of the driving switch. The relay contact is connected for energizing the controlling device for the fuel quantity adjustor whereas the energization and deenergization of the fuel shut off valve is effected immediately via a decoupling member. When the driving switch is opened and the engine is running during the given time delay interval, an error signal is generated indicating a malfunction of the fuel shut off valve.

    Abstract: The invention is directed to a safety arrangement for an internal combustion engine with self-ignition such as a diesel engine or the like wherein the operational signals of throttle position, rack travel and rotational speed are continuously monitored and compared with upper and lower limit values for these signals. From this comparison, comparison signals are generated and are combined with each other to provide an overall monitoring of the operation of the diesel engine so that the latter can be shut off when impermissible ranges of operation are present or, if conditions permit, the engine can be switched to an emergency mode of operation so that the motor vehicle may be driven to the next service station for repair.
