Adaptation of the exhaust gas sensor controls to asymmetrical degradation reactions

摘要

Methods and systems are described, for converting an asymmetrical deterioration in reaction of an exhaust gas sensor used in a symmetric deterioration in reaction is made available. In an example has a process, the adaptation of the fuel injection in response to a modified exhaust gas oxygen - feedback signal from a exhaust gas sensor, wherein the modified exhaust gas oxygen - feedback signal by converting an asymmetrical reaction of the exhaust gas sensor is changed in a symmetric reaction. The method can, in addition, the adaptation of one or more parameters of a first control device of the exhaust gas sensor, which on the basis of the changed have symmetrical reaction.
