ABSTRACT:
By taking into account the deviation between a desired value, determined from a model for a secondary-air mass flow and an actual value of the secondary-air mass flow, detected by an airflow sensor, a correction value is obtained. From the correction value, together with a main-air mass flow that is present in an intake tract of the internal combustion engine and a pilot control value for an air/fuel ratio, a correction factor for correcting an injection duration is derived.
