Abstract

Official abstract text for this publication.

The disclosure relates to a method for operating a fuel delivery device of an internal combustion engine, in which method an electromagnetic actuating device of a volume control valve is switched such as to set a delivery volume, wherein a control of the electromagnetic actuating device for moving an armature of the electromagnetic actuating device from a first position to a second position comprises at least three phases, wherein in a first phase a coil of the electromagnetic actuating device is permanently connected to a voltage, and wherein in a second phase the coil is periodically connected to the voltage with a first frequency and with a first duty factor, and wherein in a third phase the coil is periodically connected to the voltage with a second frequency and with a second duty factor.

First claim

Opening claim text (preview).

The invention claimed is: 1. An actuation circuit for actuating an electromagnetic activation device of a quantity control valve, comprising: an actuation mechanism configured to perform an actuation of the electromagnetic activation device to move an armature of the electromagnetic activation device from a first position to a second position in at least three phases, including in a first phase, continuously connecting a coil of the electromagnetic activation device to a voltage;…
