Abstract
An internal combustion engine () is operated in dependence upon operating characteristic variables such as rpm (nmot) of a crankshaft (), temperature (Tmot) of the internal combustion engine () and/or temperature of the intake air (Taev). In the method, a temperature (Taevk) of the inducted air in the combustion chamber () is, at least in approximation, obtained from a detected or modeled temperature (Taev) of the inducted air in a region remote from the combustion chamber. To simplify the programming, it is suggested that the determination of the temperature (Taevk) of the inducted air in the combustion chamber () takes place under the assumption that the inducted air has a modeled or detected initial temperature (Taev) and that the intake air comes into thermal contact with a typical component () during a contact time (tcontact) which is typical for a type of the internal combustion engine () and for an operating state of the internal combustion engine () and the typical component has a modeled or detected temperature (Tev).
