Definitions

  • DE 197 34 670 C1 describes a method for checking the exchange of Lambda sensors known that in internal combustion engines with at least two separate exhaust pipes can be used. Air is released for testing an in-vehicle air source through the exhaust pipe of the lambda sensor fed so that the correct connection can be checked based on the response time can.
  • this method can only be used on vehicles with an air source apply.
  • the runtime of the step response is determined from one probe to the next probe. Depending on whether this runtime exceeds or falls below a difference threshold value, a correct or incorrect installation state is recognized.
  • the threshold value can be 0 and positive reaction time differences indicate correct installation and negative reaction time differences indicate reversed connected O 2 sensors.
  • the error signal can advantageously be sent to an engine control unit and / or to a Display device are output. It can also be sent to one of the Internal test device connectable, external test device are output, so that the exchange test can be carried out in a stationary workshop.
  • Fig. 1 shows a section of an exhaust line 1 of an internal combustion engine, not shown.
  • the internal combustion engine is connected to exhaust pipe 2 via exhaust manifolds.
  • the arrow indicates the direction of flow of the exhaust gas.
  • An O 2 sensor 3 is arranged in the exhaust pipe 2 and measures the oxygen content of the exhaust gas.
  • a catalytic converter 4 connects downstream of the exhaust gas line 2, which in the exemplary embodiment shown is designed as a 3-way catalytic converter and is used for exhaust gas purification. After flowing through the catalyst 4, the exhaust gas reaches the exhaust line 5, from where it is led to a silencer, not shown.
  • An O 2 sensor 6 is fastened in the exhaust line 5. Both O 2 sensors 3, 6 are completely identical and connected to a control device 9 via electrical lines 7, 8.
  • the control device 9 - which can be an integral part of an engine control system - receives the sensor signals of the exhaust gas probes 3, 6 and uses them as input variables for fuel injection.
  • the control device 9 is connected to the fuel injection system (not shown in the figure) via a signal line 10. Alternatively or additionally, the control device 9 can also be connected to an engine control unit. Another output of the control device 9 is led to a display device 13.
  • the internal combustion engine Before the method is carried out, the internal combustion engine must be in an operating state in which the exhaust gas probes must detect a stable air-fuel ratio.
  • the diagram of FIG. 2 shows the typical signal curve of the O 2 sensors while the method is being carried out.
  • the exchange test can be carried out by the control device 9, an engine control unit or an external test device.
  • the signal is forwarded via the signal line 10. If the sensors have been reversed, a signal is output to a display device which is designed as a signal lamp 13.
  • a signal from the signal lamp 13 is unambiguous when there are only 2 O 2 sensors. If there are more than 2 sensors, the signal lamp could be replaced, for example, by a single or multi-digit digital display which shows the numbers of the sensors installed in the wrong way round.
