摘要： In a device and a method for ignition of an internal combustion engine having at least one cylinder is described, the device includes a central control unit and peripheral units, each being allocated to one cylinder, digital control signals being sent from the central control unit to the peripheral units, triggering the peripheral units to ignition of the respective cylinder, measured values describing states in the peripheral units being determined by the peripheral units and sent to the central control unit as a function of the measured values, at least one time difference between the control signals and the diagnostic signals being determined by the central control unit for analysis of the diagnostic signals.

摘要： A device for detecting the position of a shaft of an internal combustion engine is described, in which a sensor disc which is connected to the shaft and has at least one reference mark is sensed by at least one sensor and the output signals obtained are evaluated in the control device. So that the position of the shaft is known immediately after the internal combustion engine is started up, the last position to be determined after the internal combustion engine is switched off and after the shaft coasts to a standstill is stored in a non-volatile memory of the control device and, after the internal combustion engine is switched on again, is used to determine and output the first fuel injections during a starting phase.In order to improve the accuracy, a detection of the direction of rotation is additionally carried out so that a correction can take place if the shaft turns backwards to a certain degree as a result of the engine swinging back.

摘要： The invention is directed to a connecting circuit for a potential-free lambda probe having a ground line and a signal line and having an offset voltage source which is connected to the ground line. This offset voltage source raises the potential of the ground line to a pregiven value relative to ground. A ground short is directly detectable in the connecting circuit of the invention in that the potential measured at the signal line drops below the offset voltage. In this way, it is no longer required as in conventional circuits to check for a ground short by enriching the mixture of an engine and to monitor the exhaust gas with the lambda probe.
