Abstract
To prevent particle emissions, the start of injection of an internal combustion engine is controlled as a function of a detected dynamics of an operating parameter of the internal combustion engine. The dynamics is detected by comparing the temporal change of the operating parameter to a threshold value. The control may be carried out such that, in particular, a value of the start of injection, determined with the aid of a regulation, is frozen for a specific holding period following the detection of the dynamics.
