Container for use in exhaust gas after-treatment system of motor vehicle to store urea solution, has element completely surrounding container, and thermally isolating substance provided in intermediate space to thermally insulate container

摘要

The container (10) has an element (12) i.e. outer container, completely surrounding the container and comprising a partial area that is arranged at a distance to a wall (14) of the container under formation of an intermediate space (16). A thermally insulating substance (18) is provided in the intermediate space to thermally insulate the container. Pressure reduced with respect to atmospheric pressure is produced in the intermediate space. A heating element is arranged in the intermediate space, where an inner area of the container is filled with reaction medium (24).
