METHOD FOR ADAPTING A FUEL QUANTITY TO BE INJECTED IN AN INTERNAL COMBUSTION ENGINE

The present invention relates to a method for operating an internal combustion engine having a [lambda] control system and a tank exhaust system. The method includes: operating the internal combustionengine including a [lambda] regulation, which sets a fuel quantity to be supplied in accordance with a predefined setpoint [lambda] value, at preset times, carrying out a filter cleaning operation for a fuel tank ventilation, as a function of the presence of a release condition of the internal combustion engine, carrying out an adaptation of the [lambda] regulation by adapting at least one adaptation parameter as a function of operating variables of the internal combustion engine, at active filter cleaning operation and upon the presence of the release condition, operating variables which arerequired to carry out the adaptation of the [lambda] regulation being recorded, at deactivated filter cleaning operation and presence of the release condition, the adaptation of the [lambda] regulation being carried out as a
