Abstract

A method for operating a fuel delivery device of an internal combustion engine includes switching an electromagnetic actuating device of a volume control valve so as to set a delivery volume. An intensity of an energy that is supplied to the electromagnetic actuating device for switching purposes, in particular of a current supplied to the electromagnetic actuating device and/or a level of a voltage applied to the electromagnetic actuating device, depends at least intermittently on a rotational speed of the internal combustion engine.
