Abstract

A method for operating an internal combustion engine having at least one fuel injection valve for introducing fuel into a combustion chamber of the internal combustion engine, the valve being supplied with a specified current intensity in order to adjust a specified flow cross-section of a fuel fluidic connection in the combustion chamber. The maximum specified current intensity during normal operation is equal to a first current intensity and during a release operation is equal to a second, higher current intensity.
