    Abstract: A control device for internal combustion engines, especially for turbocharged diesel engines. The control device is arranged to generate a control distance proportional to the amount of air supplied to the engine. The control device includes a pressure chamber charged by the intake air pressure, which is separated from the back-pressure chamber by a membrane. A stop abuts against the membrane and is scanned via an intermediate lever by a supply volume adjustment element of a fuel pump. The reference absolute pressure in the back-pressure chamber is positioned between a throttle with variable throttle diameter and a throttle with fixed throttle diameter. A vacuum pump aspirates air via the throttle with fixed throttle diameter, connected to atmospheric pressure, and the throttle with variable throttle diameter is arranged to respond to the reference absolute pressure.

    Abstract: The invention is directed to a safety arrangement for an internal combustion engine with self-ignition such as a diesel engine or the like wherein the operational signals of throttle position, rack travel and rotational speed are continuously monitored and compared with upper and lower limit values for these signals. From this comparison, comparison signals are generated and are combined with each other to provide an overall monitoring of the operation of the diesel engine so that the latter can be shut off when impermissible ranges of operation are present or, if conditions permit, the engine can be switched to an emergency mode of operation so that the motor vehicle may be driven to the next service station for repair.

    Abstract: A fuel injection nozzle for internal combustion engines, in which the valve needle together with the valve seat of the nozzle body forms an electric switch which by its opening and closing indicates the injection onset and the injection duration. A spring-elastic conductive element is disposed inside the closing spring and connects the attachment piece with the valve needle.

    Abstract: 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.
