摘要： The invention relates to an electronic circuit arrangement for triggering excitation windings of electromagnetic components, provided with supplementary circuit elements, in particular free-running circuit elements, preferably solenoid valves (MV.sub.1 to MV.sub.n), whereby in order to provide a flexible open-loop control, the components are each connected in series to a controllable contact element (3). To reduce the degree of complexity of the circuit, the manufacturing price and the space requirement, it is proposed that the connecting terminals (1, 4) of this series connection lead directly, and the connections (2) between the components (MV.sub.1 to MV.sub.n) and the contact elements (3) lead via diodes (D.sub.1 to D.sub.n), respectively, to a collecting point (A, B, C), to which collecting points (A, B, C) is linked one and the same supplementary circuit-element configuration (T.sub.F,C.sub.L,10,11) shared by all components. Accordingly, the component parts of the supplementary circuit elements are subject to multiple use; they are available to all of the electromagnetic components.

摘要： The invention is directed to a measuring arrangement for detecting injection-begin in an internal combustion engine equipped with fuel injection valves. The measuring arrangement includes an inductive position transducer controlled by a current source. The current source is regulated against changes in the level of the supply voltage and elements for stabilization against noise impulses on the supply voltage are provided. The operating point of the output transistor of the current source is regulated in response to sharp drops in the level of the supply voltage thereby obtaining an improved signal-to-noise ratio. The output current of the current source is stabilized with respect to noise by elements of a coupling connected between the base of the output transistor and the supply voltage. By controlling the output current of the current source in dependence upon the rotational speed and/or the amplitude of the output signal of the measuring arrangement, it is possible to obtain an injection-begin signal of constant amplitude over the entire range of the rotational speed, temperature, and fabrication tolerances of the sensors.

摘要： An emergency control apparatus is proposed for a fuel metering system in a Diesel engine, where the signal processing unit (microcomputer) and/or a regulator can be bypassed. In the case of the failure of the signal processing unit, the position signal of the driving pedal is switched more or less directly to the regulator for triggering the control unit for the quantity-determining member, and if there is a failure of the regulator, a purely proportional regulator comes into action. It is thus assured that even in the case of failure emergency operation is guaranteed, the course of which emergency operation can essentially be influenced only by the driver of the vehicle.

摘要： The inductance of a variable inductor is put in series with a resistor to provide a delay circuit at the output of an amplifying path and the delayed voltage is fed-back to produce square waves having a period representative of the induct. The amplifying path includes a first amplifier and a final stage that includes a transistor. A second transistor is connected to a voltage supply line feeding the final stage and the delay network and is also connected to the final stage in such a way that the second transistor conducts when the first transistor of the final stage is blocked and so that the second transistor is automatically blocked when the output of the final stage is at a low potential. The base of the second transistor is connected through a resistance to a battery voltage line at a somewhat higher potential than that of the voltage supply line for the final stage. It is useful to provide an additional amplifier to operate the second transistor with its input coming from the feed back line supplied by the variable inductor and its network resistor, preferably through a low-pass filter. For adjustments that may be necessary when the inductor of a system is replaced, the characteristic curve of the evaluation circuit can be additively shifted by interposing a resistance-capacitance delay followed by an amplifying comparator in the amplifying path, preferably between the preliminary amplifier and the final stage.

摘要： The protective circuit against overpoling and overloading of an electronic consumer includes a combination of a zener diode connected parallel to the consumer and a parallel connection of a fuse and a conventional diode connected in series with one power supply terminal. Preferably an additional fuse is connected in series between the power supply and the first-mentioned fuse. In the case of a polarity reversal, a fuse burns out, but after restoring normal operational conditions the protective circuit permits operation of the consumer.

摘要： A control apparatus for a fuel metering system including a fuel pump is proposed, where in the case of a Diesel engine with insufficient voltage during starting, the final control element for the governor rod of the fuel pump is uncoupled from the signal processing unit and connected directly to a supply voltage line. It is thereby possible to prevent indefinite output signals of the signal processing unit, which appear in case of insufficient voltage, from having any effect, and simultaneously it is possible to attain reliable starting of the engine.
