Abstract:
(DE) Die Erfindung bezieht sich auf einen Tank (10) zur Bevorratung eines Reduktionsmittels, insbesondere Harnstoff oder einer wässrigen Harnstofflösung. Der Tank (10) ist Umgebungstemperatur ϑu ausgesetzt und umfasst einen Tankboden (34), Tankwände (14) und eine Tankdecke (18). Zumindest an der Oberseite des Tanks (10) befindet sich ein ein Einfrieren des bevorrateten Reduktionsmittels in eine gezielte Richtung bewirkendes isoiationselement (22, 38).
(EN) The invention relates to a tank (10) for storing a reduction agent, particularly urea or an aqueous urea solution. The tank (10) is exposed to an ambient temperature ϑu and comprises a tank bottom (34), tank walls (14) and a tank lid (18). At least on the upper side of the tank (10), an isolation element (22, 38) effecting freezing of the stored reduction agent in a certain direction is provided.
(FR) L'invention concerne un réservoir (10) stockant un agent réducteur, en particulier de l'urée ou une solution aqueuse d'urée. Le réservoir (10) est exposé à une température ambiante ϑu et comprend un fond de réservoir (34), des parois de réservoir (14) et un couvercle de réservoir (18). Il se trouve au moins sur la face supérieure du réservoir (10) un élément isolant (22, 28) qui provoque dans une direction voulue une congélation de l'agent réducteur stocké.
