Problems solved by technology

[0011] Finally, the air cushion under the filter material causes a thermal insulation between the liquid regions on both sides of the filter, thus making the required heating or thawing of the liquid reducing agent in the tank difficult at low ambient temperatures

Embodiment Construction

[0032] According to the fluid box 2 of the present invention in figure 1 The embodiment shown in has a bottom 4 and side walls 6a, 6b which delimit a tank volume for storing fluid. Additionally, fluid tank 2 typically has a figure 1 A removable or fixed cover, not shown, is provided with a filling and venting device, which enables the filling of fluid into the tank volume.

[0033] exist figure 1 The fluid level (fluid level) of the fluid tank 2 shown in is marked with A.

[0034] Inside the tank volume of the fluid tank 2, a filter box 8 is formed, which has a filter box bottom 10 extending substantially parallel to the bottom 4 of the fluid tank 2 and a filter box bottom 10 extending substantially parallel to the side walls 6a, 6b of the fluid tank 2. Filter box - side walls 9a, 9b.

[0035] The fluid box 2 and / or the filter cassette 8 can also be formed by a round, eg elliptical or circular cross section in plan view with a single surrounding side wall 6a, 6b, 9a, 9b. ...

Abstract

The invention relates to a fluid tank (2) for storing a liquid reducing agent for emission reduction, comprising a filter box (8) arranged inside the fluid tank (2), said filter box being delimited at least in some regions by a filter material (12), and a suction pipe (14) which is guided into the filter box (8). At an upper end (15) facing away from the bottom of the fluid tank (2), the suction pipe (14) has a first suction opening (16) and at the circumference below the upper end (15) the pipe has at least one second suction opening (18).

Description

technical field [0001] The invention relates to a fluid tank with a filter system, in particular for storing a reducing agent of an exhaust gas reduction system, and to a method for sucking fluid out of such a fluid tank. Background technique [0002] In internal combustion engines, especially diesel engines, due to emission regulations it is especially necessary to reduce the nitrogen oxides (NO x ). [0003] known to reduce NO x The most common method is the so-called SCR method, in which a liquid reducing agent, especially an aqueous urea solution ("AdBlue"), is injected into the exhaust system of an internal combustion engine in order to reduce the nitrogen oxides contained in the exhaust gas to nitrogen (N 2 ) and water (H 2 O) [0004] The reducing agent in liquid form is usually held in a tank and is pumped out of the tank by a pump in order to be supplied to the injection system. [0005] A tank of this type usually contains a filter which is arranged upstream o...
