  • Patent number: 5497748
    Abstract: A device for recognizing the angular position of a rotating part is described in which the rotating part is a pick-up disc (14) provided with a multiplicity of regular angle marks (11) and a distinguishable reference mark (12), which is formed, for example, by two missing angle marks (11). The number of angle marks is (n-2), where n is a number which is divisible by as many numbers as possible corresponding to different numbers of cylinders and, for example, is 36. The voltage sequence generated in the sensor (15) is analyzed in the control unit (19), unambiguous cylinder recognition being obtained after the recognition of the reference mark (12) by comparison with a camshaft signal. The analysis of the voltage sequence also supplies the rotational speed and flanks, which can be predetermined, of the pulse sequence used for ignition and/or injection control.

  • Patent number: 5134987
    Abstract: The invention relates to ignition circuit monitoring in an internal combustion engine, where a sensor signal is generated in the course of each ignition by an ignition current sensor (5), which is supplied via a pulse shaper (6) to a memory unit (7). An ignition computer (4) reads out the contents of the memory following each ignition or each sensor signal and resets the memory unit (7) prior to the next ignition. Thus, when the sensor signal is missing, the ignition computer (4) detects the lack of ignition and an appropriate control signal is made available for control actions.
