Beschreibung
Zusammenfassung:	A urea tank and a fuel tank assembly. The fuel tank assembly comprises: a casing, wherein the casing comprises an upper casing (11), a middle casing (31) and a lower casing (51), and the upper casing (11), the middle casing (31) and the lower casing (51) are separately welded so as to form a cavity which comprises a fuel cavity. The urea tank and the fuel tank assembly are formed by welding after injection molding, so that not only does the casing have uniform wall thickness and high mechanical strength, but the stress of welding is also dispersed at the upper and lower ends of the casing by means of providing the upper casing, the middle casing and the lower casing and welding the three casings separately. On one hand, the stress concentration of the welded part of the casing is reduced, and the cracking of the welded part is prevented. On the other hand, since a middle region of the casing is subject to the maximum flow impact force of a sloshing liquid such as fuel oil, welding seams in the middle part of
