摘要： A high-velocity carburetor for an Otto engine comprising a slide for changing the cross-section of the suction pipe, a nozzle connection receiving nozzles and a profiled nozzle needle seated on the slide and controlling the cross-section of the nozzle. One object is the precise adjustment of the air admixture and thus an optimum mixture regulation as a function of the most important parameters for the operational conditions. The nozzle connection contains two nozzles, situated coaxially to one another and separated from one another by an intermediate chamber. The intermediate chamber is connected to an outlet channel of a flow control value having a ferromagnetic membrane-like valve plate. The valve plate is operable by two coils opposing each other and being connected to push-pull outputs of a pulse generator with adjustable pulse duty factor. An input channel of the flow control valve is connected with the atmospheric air via an air filter. For the control of the pulse duty factor an address memory is provided which can be addressed by load values, speed values, and temperature values and which contains in the form of a performance characteristic field information values for the pulse duty factor so that the pulse duty factor and thus the air admixture in the intermediate chamber can be adjusted in accordance with said information values.

摘要： A device for the angular adjustment of a camshaft of a combustion engine according to speed and load conditions and to the angular position of the camshaft with respect to a driving wheel being controlled by an adjustable mechanism. The technical problem is the angular adjustment of the single or multiple camshafts with respect to the crankshaft according to speed and load conditions. Tooth pulses, or counting pulses, corresponding to the angular position of the crankshaft (2) and reference pulses corresponding to a particular angular reference position (singular tooth) are generated by a transducer, or pulse generator, controlled by the toothed ring associated with the crankshaft and the ignition circuit (13). An address counter (10) is reset by the reference pulses and incremented by the tooth pulses so that the output of the counter provides digital address signals corresponding to the actual angular position of the crankshaft (2). The output signals of the address counter and digital signals corresponding to load conditions are input to a correction processor with memory, (20) the output of which provides a camshaft adjustment signal. During pre-set engine operational periods, a buffer memory ( 21), controlled by the tooth-pulse time base signal, stores an adjustment signal used as a camshaft correcting variable, which is then delayed under asynchronous clocking and fed into an electromechanical control device (FIG. 3) which effects a rotary-then-linear displacement of a control member (31) and subsequently an angular corresponding displacement of the camshaft(s) to the correcting variable.

摘要： A mixture control for an internal combustion engine with a lambda probe and with a memory device containing nominal values for the fuel supply dependent on operational values of the engine, as load, rotational speed and temperature. The mixture control renders it possible to optimize the consumption and/or emission, under consideration of the operating conditions, in the entire moving range of an internal combustion engine. The memory device comprises address positions selectable by the operating values of the internal combustion engine and also by the actual lambda value, and stores nominal values for the fuel supply in the form of a map for a characteristic field. The probe voltage and the internal resistance of the lambda probe are determined. A temperature-corrected signal denoting the actual value of lambda is generated by determining a correction value from two measuring signlas such as probe voltage and the internal resistance of the probe, and the signal denoting the corrected actual value is fed to the memory device as address signal.

摘要： Circuit for generating a trigger pulse delayed within a period of a periodical motion of variable periodic time, the phase lag relative to a zero phase being dependent on the periodic time and other parameters, a zero pulse and angle pulses starting at zero 5 phase being generated, the pulse frequency being inversely proportional to the periodic time, the angle pulses being fed into a counter and correcting data being generated within every period during a constant-time window. The technical problem the invention relates to is to design the circuit so that a single sequence of angle pulses may be evaluated and no control pulses are necessary except a reference pulse for defining a reference phase. According to the invention the following solution to the problem is proposed: during a constant-time window the angle pulses are varied under control so that each single pulse may be duplicated, counted normally, or suppressed. In this way correcting pulses according to individual characteristics may be generated during the time window.

摘要： The operation of an automated friction clutch between the output element of the engine and the input element of the variable-speed transmission in a motor vehicle is regulated by a fluid-operated system which receives signals from an evaluating circuit. The evaluating circuit receives signals from a number of sensors which monitor the RPM of the engine, the RPM of the input element of the transmission, clutch travel, the position of the throttle valve, the position of the shift linkage, the position of the gas pedal and other parameters. The fluid-operated system can select the condition of the clutch during starting, driving, acceleration, parking, driving in reverse and/or parking of the motor vehicle and/or during transitions between such stages of operation.
