Title (EN) METHOD AND DEVICE FOR INCREASING THE UREA CONCENTRATION OF A UREA SOLUTION ON BOARD OF A VEHICLE
(FR) SYSTÈME ET PROCÉDÉ D'AUGMENTATION DE LA CONCENTRATION EN URÉE D'UNE SOLUTION D’URÉE À BORD D'UN VÉHICULE
Abstract:
(EN) The invention relates to a method and a device for increasing the urea concentration of a urea solution in a container of a vehicle. Said method comprising the steps of: a) flowing a first gas above a first urea solution and/or blowing a second gas in the first urea solution, b) Obtaining a second urea solution the urea concentration of the second urea solution being higher than the urea concentration of the first urea solution.
(FR) L'invention concerne un procédé et un dispositif d'augmentation de la concentration en urée d'une solution d'urée dans un réservoir de véhicule. Ledit procédé comprend les étapes consistant à: a) faire circuler un premier gaz sur une première solution d'urée et/ou souffler un second gaz dans la première solution d'urée, b) à obtenir une seconde solution d'urée, la concentration en urée de la seconde solution d'urée étant supérieure à la concentration en urée de la première solution d'urée.
