Abstract:
A method for the exhaust gas aftertreatment of a combustion engine having an exhaust system in which at least three catalytic converters and at least three lambda probes are disposed. Downstream of a first catalytic converter, an actively heatable catalytic converter is provided, which is actively heated at a start of the combustion engine. The lambda control of the combustion engine is carried out in each case by that lambda probe disposed downstream of the respective last catalytic converter to reach the light-off temperature thereof. Also, an exhaust gas aftertreatment system for implementing such a method.
