摘要： A distributorless ignition system using a dual-spark ignition coil generates a signal indicative of which of the two cylinders associated with the dual-spark coil is operating in its power stroke by means of a single detector (15) connected to a predetermined one of the cylinders. The output of the detector is fed to a sample and hold circuit (21) which supplies the peak value from the detector to the control unit (10) of the ignition system where the peak value is evaluated and identified as indicating that the predetermined cylinder is in its power stroke when the detected peak value signal is at its higher level. Conversely, when the peak value signal is at its lower level the control unit determines that it is the other of the two cylinders which is in its power stroke and signals this accordingly.

摘要： A monitoring device for an ignition end stage in an internal combustion engine comprises a make time limiting device for the ignition end stage (5), which is supplied by a supply voltage (UBATT). The make time limiting device is set in operation by a control signal when the make time is determined, and controls the ignition end stage for ignition in the event that ignition does not occur before the limiting time expires. According to the invention, the duration of the limiting time (t = f (UBATT)) can be varied, in function of the supply voltage (UBATT), so that it decreases with increase in the supply voltage (UBATT). This prevents thermal damage or destruction of an ignition end stage due to excessively long make times. In addition, overdimensioning of an ignition end stage is unnecessary.

摘要： The description relates to a device by means of which sine-wave signals with a singularity can be further processed into square-wave signals and by means of which the singularity can be clearly and reliably recognised. The sine-wave pulses are converted into square-wave pulses in such a way that the sides of the square-wave pulses always lie in the same place regardless of the height of the sine-wave signals. This is made possible because a side alternation in the square-wave signals is always triggered when the sine-wave signals pass through zero. The necessary signal processing and logic comparisons are performed in a suitable circuit and they also permit clear reference mark recognition.

摘要： A distributorless ignition system for an internal combustion engine comprises one spark coil for cylinder of the engine, a first reference signal generator for producing a first signal indicative of each rotation of the engine, a second reference signal generator for producing a second signal indicative of every second rotation of the engine, and a processor for evaluating the advance and dwell angles of an ignition pulse to a selected spark coil determined from a logical combination of said first and second signals. During starting, the processor is arranged to operate in a dual-spark mode for the first rotation of the engine and produce two ignition pulses simultaneously for each first signal, one to each of two cylinders which are 360 DEG out of phase with each other. During running of the engine, the second reference signal generator is monitored and if found to be faulty, the processor will change from a one-spark mode to a dual-spark mode.

摘要： An ignition circuit for an internal combustion engine comprises a customary primary circuit. The secondary circuit is modified by connecting the end (21) of the secondary winding (L2) not connected to the central electrode of a spark plug (24) to vehicle earth so as to cause the discharge current of the capacitance of the secondary winding (L2) to flow directly to earth whereby substantially reducing radio frequency interference and inhibiting interference in the cable harness due to ignition interference.

摘要： The description relates to a device for detecting the angular position of a rotating component in which the rotating component is fitted with a pickup disc (14) with a plurality of regular angle marks (11) and a distinguishable reference mark (12) is formed, for example, by two missing angle marks (11). The number of angle marks is (n-2) where n is a number divisible by as many numbers as possible corresponding to different numbers of cylinders, and is, for example, 36. The voltage sequence generated in the sensor (15) is evaluated in the control device (19). Once the reference mark (12) has been recognised by comparison with a camshaft signal, the cylinder concerned is unmistakable. Evaluation of the voltage sequence also provides the rotation speed, and predeterminable edges of the pulse sequence are used to control the ignition and/or injection system.

摘要： A device is disclosed for protecting a motor vehicle controller (10) against illicit exchange. The core of the invention is a function-inhibiting device (11, 12, 13, 27) associated with a connection between the controller (10) and the connecting element (20) of an electric supply line (21). The function-inhibiting device (11, 12, 13, 27) places the controller (10) and the connecting element (20) in a predetermined connecting position. This connecting position may only be interrupted in a non-destructive manner by supplying an unlocking code to the controller (10). When an attempt is made to interrupt the connection by force, the function-inhibiting device (11, 12, 13, 27) causes an irreversible interruption of the corresponding connection.

摘要： In a pressure sensor (11), the force is introduced via a membrane (14) and a plunger (18) onto a piezoresistive measuring element (21). The measuring element (21) is part of a monocrystalline silicon chip (20). The piezoresistive measuring element (21) is connected to the monocrystalline silicon chip in a half-bridge circuit or a Wheatstone bridge circuit. Also on the silicon chip (20) are a stabilizing circuit (23), an amplifier circuit (24) for the measurement signal picked up and electrical elements for temperature compensation of the zero point and sensitivity of the measuring element (21). Elements (51) for adjusting the functions with the help of additional connections are also present. The sensitivity and zero point of the pressure sensor in the fully assembled chip (20) can therefore be adjusted from the outside without laser adjustment. The pressure sensor (11) is also relatively small and compact.

摘要： Proposed is a high-voltage switch which carries out the function of an ignition-voltage distributor for an internal-combustion engine with static high-voltage distribution. The high-voltage switch comprises a cascade of semiconductor elements, this cascade being formed by patterning a single mono-crystalline silicon wafer (1) as a single chip with adjacent semiconductor elements (12) so that, when the pn transition zones (4) are irradiated with light, the breakdown voltage of the high-voltage switch is lowered.
