Abstract
An arrangement is provided for feeding a liquid additive from a receptacle into a fuel pipe or into an exhaust line of an internal-combustion engine of a motor vehicle. The receptacle is fillable with additive from a larger storage tank that is also accommodated in the motor vehicle by way of a connection line that can be blocked by a shut-off element. A pump is installed in the receptacle or in the connection line. A heating device for heating at least a partial volume of the additive is present in the receptacle. A blockable return line branches off into the receptacle from the connection line between the pump and the shut-off element.
