Abstract
Official abstract text for this publication.
A method for operating a metering apparatus for reducing agent includes providing the metering apparatus with at least one movable pump element movable between upper and lower reversal points to convey reducing agent into an exhaust-gas treatment component, and at least one position transmitter for determining a pass of the movable pump element. In the method, a first detection of a position of the movable pump element is provided by the position encoder. Subsequently, the movable pump element is moved and reducing agent is metered into the exhaust-gas treatment component. Thereupon, a second detection of a position of the movable pump element is provided by the position encoder, and subsequently a first quantity of reducing agent which is metered between the first and second detections is determined. A metering apparatus and a motor vehicle having a metering apparatus are also provided.
First claim
Opening claim text (preview).
The invention claimed is: 1. A metering apparatus for feeding reducing agent to an exhaust gas treatment component, the metering apparatus comprising: at least one movable pump element configured to be moved between an upper reversal point and a lower reversal point; at least one position transmitter configured to detect a pass by said at least one movable pump element; at least one injector configured to feed the reducing agent from said at least one movable pump element into…
