Abstract

A method for operating an internal combustion engine is described, in which fuel is injected by an injector into a combustion chamber. The injector has an activatable piezoactuator. In the method, a precontrol setpoint for activating the piezoactuator is generated. The precontrol setpoint is combined with a charge regulation of the charge quantity conveyed to the piezoactuator.
