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 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 carburetor has a throttle member in the form of a slide for controlling the air induction passage, the slide being displaceably guided in a sealed and sliding manner on planer edge areas of guide surfaces of a surface extending substantially at right angles to the induction passage, the slide being relieved from vertical downward pressures exerted on the guide surfaces by the manifold vacuum acting on the underside of the slide by an unloading mechanism controlled by the vacuum force, the unloading mechanism comprising lifting rails which are pivotally mounted for engagement with the slide and include rollers that may be raised or lowered by devices that are responsive to the change in vacuum below the slide as the slide moves closed or open to counteract the differential pressure force acting on the slide.

摘要： A carburetor has a throttle member in the form of a laterally movable slide controlling the size of the induction passage. At planar edge areas of the guide surfaces, the slide is sealingly and slidably guided on a surface extending normal to the induction passage. The slide is unloaded from vertical downward pressures exerted on the guide surfaces by an unloading mechanism controlled by engine manifold vacuum. Such an unloading mechanism can consist of a parallelogram lever arrangement which through a pressure chamber actuates lifting rails arranged laterally to the guide surfaces. The slide is supported on the lifting rails by roller arrangements.

摘要： In an apparatus for altering the valve timing of an internal combustion engine as a function of load and rotational speed, a helical pinion is mounted so as to be axially displaceably, but non-rotatably mounted on the camshaft. The pinion is in engagement with an axially fixed helical intermediate gear-wheel driven by the crankshaft. The helical pinion is connected to the camshaft by a splined connection and has tracks for a radial ball bearing, one of which is formed on a sleeve which is guided axially displaceably, but non-rotatably in a part of the camshaft housing by way of a key and keyway connection. The sleeve has a toothed rack portion which is in engagement with an actuating pinion which is driven by an actuating drive controled by a sensor sensing the operating parameters of the engine.

摘要： The invention relates to a camshaft mounting for a one-piece camshaft supported in a cylinder head having three undivided bearing blocks. The camshaft 5 has three bearing portions of small diameter. One end bearing block (4) has a bore of the same diameter as the bearing portion 8. The middle bearing block 3 has a bore 12 of the same diameter as the bearing portion 7 and a cut-out 13 shaped to allow the cams 9 to pass through one by one if the camshaft 5 is correctly oriented. The last bearing block has a larger bore 16 and is fitted with a bush 15 after insertion of the cams of the camshaft. The camshaft is assembled by sequentially rotating it to align the cams one by one with the cut-out 13 and axial displacement. The bush 15 may be inserted after the camshaft has been slid into position or may be placed over the bearing portion 6 before the camshaft is finally pushed home.
