Abstract
In a method for operating an internal combustion engine with intake manifold injection and direct injection, a value of at least one parameter that is correlated with an exhaust gas of a combustion chamber of the internal combustion engine and that is influenced by purging of uncombusted fuel through the combustion chamber into the exhaust gas is ascertained, and, if it is concluded, based on the ascertained value of the at least one parameter, that uncombusted fuel is purged, at least one operating parameter for filling the combustion chamber is adjusted.
