Abstract
A method for assessing an injection behavior of at least one injection valve of an internal combustion engine includes putting the internal combustion engine into a special operating mode defined by control parameters and operating the engine in the special operating mode during a diagnostic time period, at least one operating parameter of the internal combustion engine being determined at least during the diagnostic time period, and at least one quantity characterizing the injection behavior of the at least one injection valve being evaluated at least during a segment of the diagnostic time period and being evaluated on the basis of the at least one operating parameter.
