This acts on the second exhaust bank 54 assigned Engine part Motor_B2 98 and accordingly to the pre-catalyst 58 of the second exhaust bank 54.

- the block 110 then outputs a calculated Lambda actual lambda-is-b2 116 before the pre-catalyst 58 of the second exhaust bank 54 off.
- the mixture adaptation is divided into several parts. So there is ever an adaptation value for an additive error, a multiplicative error and possibly still for a temperature-dependent error.
- a lambda probe u.a. determines the mixture deviation for all cylinders. in the The case of a two or more exhaust system is often the sensor executed several times, i. each exhaust bank points in the direction of flow a pre-catalyst, a lambda probe in front of the pre-catalyst and a lambda probe after the precatalyst.
- each exhaust bank points in the direction of flow a pre-catalyst, a lambda probe in front of the pre-catalyst and a lambda probe after the precatalyst.
- the invention proposes the additive Adaptation value for the mixture precontrol, which contains the additive error of the Mixture feedforward corrected, to measure or calculate only on an exhaust bank and to reflect on the other exhaust banks.
- the additive adaptation value for the mixture precontrol is formed, Which immediately after engine leakage a lambda probe before the pre-catalyst having. This simplifies the adaptation of the mixture precontrol for Matware exhaust aftertreatment systems, since only the multiplicative adaptation value for the mixture precontrol, which is the multiplicative error of the mixture precontrol corrected, must be determined separately for each exhaust bank.
- Exhaust gas tank specific deviations on the exhaust bank / exhaust gas banks, in particular for the multiplicative adaptation range, are over a continuous Lambda control after precatalyst based on a binary or continuous Lambda signal balanced. This can be in the concept with Tanauer Exhaust after-treatment system on the lambda probes before the pre-catalyst be dispensed with in all exhaust banks except for an exhaust bank.
