    摘要： A device is proposed for the adjustment of a quantity-metering member of a fuel injection pump in an internal combustion engine with self-ignition, comprising an electric circuit arrangement for a control signal dependent on operating parameters, this signal inffluencing the position of the quantity-metering member via an electromagnetic servo unit wherein the electric circuit arrangement includes at least one series circuit made up of a minimum value selection stage, a maximum value selection stage, and a servo unit controller for the quantity-metering member and the output signals of at least two set-point stages for, in particular, the speed, the smoke limit, equalization, and exhaust gas temperature can be fed to the minimum value selection stage with the maximum value selection stage additionally coupled to a start control stage. In addition to the use of the device as a total controller, i.e., the electric circuit arrangement alone determines the position of the quantity-metering member and no mechanical controller is additionally provided, the device can also be utilized where only a regulated stop for the quantity-metering member, for example a control rod, is present as the control member ("signal mixing"). The purpose of the proposed device is to furnish an electronic speed regulation for idling and for intermediate speeds, beyond the quantity-limiting functions of equalization (limitation of the injection only in dependence on the speed), smoke limit, and exhaust gas temperature limit, in case of a total controller as well as in case of signal mixing with the aid of a controlled servo unit, so that the speed is maintained constant at the preset and/or desired value even in an unstable condition during varying loads, for example, due to the additional connection of auxiliary units.

    摘要： A device is proposed for drift compensation in fuel metering systems, in which it is not the metered quantity as such which is controlled in closed-loop fashion, but rather only the position of a quantity-determining member. The object of the invention is to maintain or re-obtain the original association between the fuel quantity and the position signal of the quantity-determining member for the purpose of providing a correct indication of the load state existing at a particular time. The drift compensation is intended to be capable of being performed manually, semi-automatically, or automatically, in an additive and/or multiplicative manner. It can furthermore be realized via a preferably rpm-dependent characteristic curve. The various values may be ascertained, for instance, in connection with running-out and running-up tests.

    摘要： An apparatus for fixing the composition of the gas content and the degree of filling of cylinders in an internal combustion engine having autoignition, including a fuel metering device to which a signal dependent at least on the position of the driving pedal can be delivered and having an exhaust gas feedback control element in the air intake line as well as an apparatus for controlling the exhaust feedback rate. The apparatus includes measurement value transducers for the at least indirectly detectable total cylinder filling and the ratio of fresh air to exhaust gas or the air ratio pertaining to the aspirated fresh air and/or the fuel metering is influenced among others in accordance with this measurement value. The detection of the total cylinder filling can be accomplished indirectly by using measurement techniques for detecting pressure and temperature in the intake manifold. Besides using pressure transducers, whose output signal may be corrected in accordance with temperature, if desired, it is also possible to use an arrangement for measurement of the total gas quantity between the exhaust feedback point and the inlet valves. The object of the proposed apparatus is to set the mixture of fresh air and exhaust gas which is optimal at any given time with respect to toxic substances in the exhaust, by means of processing as many observable influencing factors as possible, and in particular by processing the total cylinder filling, which is of significance especially in terms of the limitation of solids in the exhaust which is expected to be made a legal requirement. Alternatively, the signal for the total cylinder filling can be used in order to adjust a suitably controllable supercharger via a governor in such a manner that the total cylinder filling (charge quantity) is constantly controlled. Thus, under altered environmental conditions, the optimal air ratio for normal conditions pertaining to the aspirated fresh air can be maintained with respect to toxic substances in the exhaust.

    摘要： Disclosed is an emergency control device for fuel dosing systems of IC engines, particularly for fuel injection devices of a diesel engine. A conventional regulating path for the fuel pump, includes a series connection of a set of data sensors, a signal processing circuit for computing a regular control signal, and a fuel regulating device connected to the fuel pump and provided with a manually or automatically controlled switching device. An emergency control branch is connected between the switching device and the sensor to function in parallel with the regular regulating device. The emergency control branch includes a nominal value generator of a signal corresponding to a maximum manifold pressure and a manifold pressure regulator controlled by output from the nominal value transmitter, to apply, via the switching device, to the fuel pump a dosing signal which causes the manifold pressure not to exceed the preset maximum value. In a further elaboration the emergency control branch includes a minimum value selector cooperating, in addition to the manifold pressure regulator, with a current control unit indicative of the gas pedal position and with an overspeed safety circuit cooperating with a rotary speed sensor. A maximum value selector is connected between the switching device and the output of the minimum value selector and controls the dosing pump in response to an idling speed stabilizer.

    摘要： The disclosure describes a method of avoiding an excessive drag torque for motor vehicles. When the accelerator pedal is released, an amount of fuel is supplied to the engine which is approximately under zero-load and which is gradually reduced over time. The occurring change of the rotational speed is monitored. When a certain rotational speed change is exceeded per time unit, the amount of fuel is gradually increased over time until a certain positive rotational speed change is recognized. Then, there is a switch-back to reducing the amount of fuel. The procedure is repeated until the vehicle has reached an operational condition with a constant rotational speed.
