    摘要: The invention is directed to a method for influencing the metering of fuel to an internal combustion engine, wherein the amount of fuel to be delivered to the engine is varied at least in dependence upon the number of revolutions or working strokes of the engine. In this method, the number of revolutions or working strokes of the engine is measured for subsequent storage in a volatile and a non-volatile storage. If a supply voltage failure causes the contents of the volatile storage to be lost, the more essential portion of this number for the engine continues to be available in the non-volatile storage. Embodiments are described explaining how the volatile and the non-volatile storage can be realized and combined. Also, a description is provided as to how the metering of fuel can be influenced in dependence upon the number of revolutions or working strokes of the internal combustion engine.

    摘要: A device is proposed for controlling the injection start to a set-point value dependent on operating parameters, in which the period of time between the appearance of an injection start signal and a reference marking (for instance, a top-dead-center signal) is counted out and the result of counting is compared with the set-point value. To avoid malfunctioning, the triggering of the counting process is possible in only one, predetermined crankshaft angle range. Various values are provided for the counting-out frequency. In the exemplary embodiment they are within the range between 50 and 200 kHz. In case of failure, a control of injection onset is effected, and as needed, a limitation of the fuel quantity as well--for instance to 70% of the respectively determined quantity.

    摘要: All but one of the microcomputers in a multi-computer system are equipped with a rapid-access read-write memory and a fixed content nonvolatile read-only memory. Each of these read-only memories, however, stores a multiplicity of varieties of one or more sets of data, so that, in the case of a computer system for a motor vehicle engine, the same system can be used in any of a large number of vehicle models. One of the microcomputers of the system has a programmable memory which is programmed at the time of installation to designate the portions of the fixed memories that are to be utilized. When the system is turned on, the programmed memory designation number is stored in the read-write memory of all of the computers of the system, with the result that the designated portion of each fixed read-only memory is always referred to in any computer of the system. It is not important that, when the system is turned off, the memory content of the read-write memories is lost.

    摘要: A control system for an internal combustion engine which has a driving-pedal position transducer, a subsequent performance graph apparatus for control values and a control device responding to these values. A delay element is provided in series with the performance graft apparatus between the driving-pedal position transducer and the control device. The purpose of the control system is to adapt the mode of response of the control device (a throttle valve, for instance, in an Otto engine or the regulator rod in a Diesel engine) to various operational states. Of special significance are rpm, the position of the driving pedal, and the change in driving-pedal position. The proposed system is efficaciously realized by means of a computer.

    摘要: A control device for protecting an internal combustion engine in the case of malfunction of its fuel regulating system is disclosed. The control device includes means which in response to the occurrence of the first braking mode of operation of the engine after start activates a suction or pump connected to the suction chamber of a fuel injection pump. Then the reaction of the engine to the suction pump is tested. If, the engine does not react to a displacement of the control rod of the fuel adjusting mechanism, then an error is present and the engine is either stopped or switched over to an emergency mode of operation. The control device is suitable particularly for a Diesel engine.

    摘要: The maximum speed in an internal combustion engine is limited by circuitry which can be adjusted to conditions requiring a lower-than-normal top speed, for example during initial delivery to the customer and during the break-in period of the engine. The top speed limiter includes a comparator for suppressing or altering the fuel injection pulses. As a feature of the invention, the reference signal applied to the comparator and representing the top engine speed can be changed either manually or on the basis of elapsed time or mileage.

    摘要: A method for regulation or control of the melting process in a three-phase arc furnace having at least three electrodes whose height is adjustable individually and independently of one another. Each phase of the three-phase current which feeds the three-phase arc furnace is assigned at least one electrode. The temperature of the three-phase arc furnace is monitored, particularly at points which are at risk of overheating, such as the walls of the three-phase arc furnace in the vicinity of the electrodes. When the three-phase arc furnace reaches a critical temperature in the vicinity of an electrode, the power emission from this electrode is reduced in such a manner that overheating of the three-phase arc furnace is prevented, and in that the power emission from the other electrodes or from some of the other electrodes is increased in such a manner that the total power emission from the electrodes is a maximum at a predetermined voltage.

    摘要: In a safety and emergency driving control method and an associated arrangement for an internal combustion engine with self-ignition used to power a motor vehicle, various operating parameters of the engine are continuously monitored and respective signals indicative of gas pedal position, engine operating speed, brake actuation, and actual control rod displacement are generated and evaluated to determine simultaneous occurrence of a modified idling operation condition and of a predetermined minimum value of the actual control rod displacement signal. In response to such a simultaneous occurrence the engine control is switched over to another regulation branch which controls the control rod displacement in accordance with a minimum value characteristic line of the control rod displacement. Further peripheral devices are included for providing starting hysteresis and excess speed protection, and for supervising the operation of the control rod displacement sensor. A supervisory device associated with a main computer of the arrangement may also be used to achieve the switch-over independently ofexternal signals.
