Abstract

In a method for controlling an internal combustion engine, during a standard operating mode a specified first fuel quantity is injected by actuating a first fuel injector during a first actuation period and by an accompanying opening of a first valve needle, and a specified second fuel quantity is injected by actuating a second fuel injector during a second actuation period and by an accompanying opening of a second valve needle, and (i) during a first calibration operating mode, a calibration actuation of the first fuel injector is performed while an actuation of the second fuel injector is carried out, or (ii) during a second calibration operating mode, a calibration actuation of the second fuel injector is carried out while an actuation of the first fuel injector is carried out.
