    摘要: 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.

    摘要: 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.

    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: 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.

    摘要: 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.

    摘要: A fuel injection nozzle for internal combustion engines, provided with a valve needle and an induction coil, which sits in a spacer plate mounted between the nozzle body and the nozzle holder. The valve needle projects into the induction coil and acts upon the magnetic domain of the induction coil by the action of its movement, whereby a signal dependent on the velocity of the needle is produced. The induction coil is provided with laterally disposed contact prongs which are connected with extended connecting wires by means of a weld or solder joint. The connecting wires lead through boreholes in the nozzle holder. The injection nozzle is distinguished by an especially small electrical line resistance, and by the fact that, with appropriate dimensioning and construction of the ends of the connecting wires, which carry the extended connection contacts, there will be no special contact measures necessary for disassembly.

    摘要: A fuel injection pump for an internal combustion engine including a low pressure sump and a sump piston, reciprocating in a cylinder, for imparting elevated pressure to the fuel for delivery to injection valves. The pressure chamber in the pump cylinder can be opened to the sump at some adjustable point of the piston stroke to limit fuel delivery. A secondary conduit between the pressure chamber and the sump includes a flow throttle that variably restricts the return flow of fuel as adjusted by fluid pressure which is regulated by a secondary fuel control mechanism. This mechanism is subject to closed-loop control via an air flow rate meter disposed in the induction tube and also acts as a limiting stop for the baffle plate of the air flow rate meter.

    摘要: An apparatus for controlling the ratio of air to fuel quantity of the operational mixture to be introduced into the combustion chambers of an internal combustion engine which includes an air flow rate meter moving under differential pressure against a constant hydraulic restoring force, which air flow rate meter adjusts a metering cross section in a supply line leading to a fuel injection pump, with the pressure drop at the metering cross section being maintained constant with the aid of a differential pressure valve. The air flow rate meter is part of a known apparatus which controls the fuel component in accordance with the quantity of aspirated air and also controls the component of exhaust gas to be fed back. The hydraulic restoring pressure for the air flow rate meter is drawn via a throttle from the supply side of a supply pump which supplies the injection pump with fuel under an rpm-dependent pressure and with a quantity of fuel intended for flushing and the pressure downstream of the throttle is maintained at a constant value by means of a pressure maintenance valve. The working chambers of the injection pump communicate only with either the injection lines or the fuel supply line controlled by the air flow rate meter, so that the control result is not adulterated by the flushing quantity or by a shutoff quantity. In this manner, the injection pump and the control device can be supplied with fuel and with pressure fluid by means of a single supply pump.

    摘要: A device for exhaust gas recycling is proposed which controls the amount of recycled exhaust gas in an internal combustion engine equipped with an injection unit so that a certain air factor is attained. The device comprises a closing element for the exhaust gas return conduit, which latter terminates into the intake manifold, this closing element being suitably constituted by a throttle valve and being directly connected to the adjusting lever or control rod of the injection pump. If this connection is established via a resilient linkage between the adjusting lever and the exhaust gas return valve, then the thus-recycled amount of exhaust gas can be dimensioned so that a specific quantity of recycled exhaust gas is associated with a specific angular position of the adjusting lever.
