Definitions
- the invention relates to a method and apparatus for operating an internal combustion engine with at least two cylinder groups, each associated with a separately Abgaskataiysato 'r with at least one lambda probe and connected thereto lambda probe control unit.
- lambda probes In order that lambda probes cannot be mixed up or connected, they would have to be mechanically coded. This is possible with different plug connections or with different cable lengths for the left and right lambda sensors. Two different lambda probes lead to a high administrative effort, additional part number and, in addition, due to the quantity effect, higher costs. In modern internal combustion engines such as gasoline engines with several lambda probes, the swapping of probes is reliably detected by means of suitable diagnostic functions. If the probes are interchanged, the probes must be plugged in at the workshop or at the end of the production line.
- DE 44 23 344 A1 relates to a method for detecting reversed connected lambda probes.
- the injection valves of which can be switched off at least one cylinder row the injection valves of one of the two cylinder rows are switched off for a certain time.
- the lambda probe signal of the lambda probe assigned to the deactivated cylinder rows is compared with a predetermined threshold value at the end of the deactivation time of the injection valves.
- a reverse connection of the lambda probes is recognized when the lambda probe signal exceeds or falls below the threshold value. If the reverse connection of the lambda probes is detected, the lambda controls are blocked and an error display device is activated.
- the invention is based on the object of providing a method and a device for operating an internal combustion engine with at least two cylinder groups, each of which is separately assigned an exhaust gas catalytic converter with at least one lambda probe and a lambda probe control unit connected to it, with an exchange of the lambda Probes without intervention in the workshop or at the end of the line.
- the invention is based on the basic idea of using software to link the probe signals to the associated cylinder groups.
- the figure shows a basic circuit diagram of a preferred embodiment of the invention.
- the voltage from probe A is applied to first and second switches, and the voltage from probe B is also applied to the first and second switches.
- the first changeover switch is connected to a cylinder group 1 and the second changeover switch is connected to a second cylinder group 2.
- the voltage from probe A is optionally connected to cylinder group 1 and the voltage from probe B is connected to cylinder group 2.
- the voltage from probe A is connected to cylinder group 2 and the voltage from probe B is connected to cylinder group 1.
- the changeover switches are preferably implemented as software switches.
- the method according to the invention has the following steps in a test mode: at least one operating parameter of a cylinder group is changed and the probe signals are monitored or recorded and the reaction is compared with expected reference patterns.
- the lambda probe the probe signal of which has behaved in accordance with a reference pattern, is then assigned to the cylinder group whose operating parameters have been changed. These steps are repeated until each lambda probe is assigned to a cylinder group.
- the probe signals of the lambda probes are linked with the respectively assigned cylinder group. In this linking step, as described above using an example, a changeover switch is actuated for each cylinder group, and the link between the probe signal and the cylinder group is thereby corrected.
- the invention has the advantages that only one cable length / plug / probe is generally usable. Even after a visit to the workshop, there is no danger that the probes will be exchanged. There is great potential for cost reduction, in particular due to the larger number of identical components, the shorter time at the end of the line during production and the lower effort for logistics during production.
