Abstract
A device for providing a liquid additive into an exhaust line includes a tank, a delivery line, a heating element formed of a posistor or PTC material for heating the additive in the tank and/or the delivery line, and a dosing device or doser for dosing the liquid additive. The dosing device has a coil and a movable component and the movable component can be moved by the coil. The coil can be connected electronically in series with the heating element by a first switching element. It is thus possible for an activation current through a heating element formed of a posistor material to be limited in magnitude in an inexpensive manner.
