    • A method and an apparatus are proposed for adapting the exhaust gas recirculation rate in internal combustion engines, in particular Diesel engines. In order to prevent the smoke which is produced at first in new engines, or when injection nozzles or the like are replaced, an adjustment is made in the exhaust gas recirculation rate, acting as a supplement to the change in this rate which is conventionally made, the supplementary adjustment being preferably performed in stages and with reference to the function of the duration of operation from the time the varying operating conditions begin. The number of injection events is counted and successive memory locations are triggered at time intervals, effecting an adaptation of the exhaust gas recirculation rate up to the final status, each stage in adaptation being stored permanently in memory as it is attained.

    • A short-circuit-resistant trigger circuit layout is proposed for an electrical consumer for motor vehicles. The trigger circuit layout is located in series with a switching transistor, which is preceded in turn by an operational amplifier whose negative input is coupled with the junction point of two resistors parallel to the transistor and whose positive input receives both an average constant potential and a dynamic switching signal. In case of error, that is, in case of a short-circuit consumer, the transistor, which has initially been switched on, switches back into its blocked state after a predetermined time constant has elapsed. The short-circuit current flowing during this open phase can be limited by means of a resistor in series with the transistor.

    • A measuring circuit (MS) for measuring the value of an impedance in an impedance network includes an oscillator device (OSZ1), a second oscillator device (OSZ2), a phase-controlled rectifier (PG), a reference/actual value comparison point (AG) and an integrator.The first oscillator device feeds a first alternating voltage of constant amplitude and constant frequency to a first output connection (A1). The second oscillator device feeds a second alternating voltage of the same frequency, but with adjustable amplitude and with phase shifted by 180.degree., to a second output connection (A2). The amplitude of the second alternating voltage depends on the phase of the signal which is transmitted to the phase-controlled rectifier via an input connection (E). If the input signal is in phase with the second output signal, the amplitude of the second output signal is reduced. However, if the input signal oscillates in opposite phase to the second output signal, the amplitude of the second output signal is increased. This change of amplitude is effected by the integrator which integrates the signal, which is rectified and compared with a reference value, and transmits the integration value as amplitude adjusting value.

    • An evaluating circuit for linearizing the output signal of a differential-choke displacement transmitter has two inductive coils each supplied with an alternating voltage with constant frequency produced by an oscillator, wherein the amplitude is adjustable and the second alternating voltage is phase-displaced relative to the first alternating voltage by 180.degree.. The signal which is picked up between the inductive coils at the input is compared, after a phase-controlled rectification, with a reference value and the deviation is integrated. With the aid of the integrated signal the regulation of the amplitude adjustment of the alternating voltages is performed. As a result a measuring signal without residual ripple is obtained, which changes proportionally to an adjustment path for example of an adjustment rod.

    • 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.
