Abstract
A process for controlling an internal combustion engine having a regulated turbocharger and integrated exhaust gas temperature is provided. The maximum cylinder filling capacity (rlmax) is taken from a stored characteristic field, which extends over the rpm (n) range. The values stored in the characteristic field are determined in the application and are standardized to a lambda value which can be preset, preferably to be lambda=1. When operating the internal combustion engine, the value of the maximum filling capacity (rlmax) taken from the characteristic field is corrected to the current fuel mixture composition.
