Problems solved by technology

This solution leads to sluggish defrost performance, also requires an additional element in the form of a heat conducting pin made of stainless steel, and moreover presents overall a large thermal resistance which does not assist the defrost performance when the reducing agent freezes
In addition, it is rather complex to create or produce a material-bonded connection between the components

Embodiment Construction

[0025] from according to figure 1 The illustration in FIG. 2 shows a storage tank 10 in which a freezeable operating / auxiliary material 12 , preferably a reducing agent, is received. Freezable operating / auxiliary materials freeze at temperatures below -11°C. Such as figure 1 As shown, a filter 14 is connected upstream of the suction channel 28 . A filter 14 may be received on a carrier 16 and include a filter web 18 . Located above the filter 14 is a heating / cooling body 20 which is surrounded by an injection-molded encapsulation 22 which usually consists of a plastic material. Furthermore, heat conducting pins 24 , for example made of stainless steel, are located in the filter cover 26 . The delivery device inlet 30 extends from the suction channel 28 to the figure 1 Delivery device not shown.

[0026] in accordance with figure 1 appears in the solution of figure 2 The thermal resistance shown in. if based on figure 2 The schematic diagram shows that at T 加热器 ,36...

Abstract

The invention relates to an apparatus for controlling the temperature of a freezable operating / auxiliary medium (12) which is stored in a reservoir (10) and is used for exhaust gas aftertreatment in compression ignition engines. An overmolding (22) on a heating element (56) forms a wall (50) of an intake duct (28) within a covering area (58).

Description

technical field [0001] The invention relates to a device for tempering freezable operating / auxiliary material stored in a storage tank for exhaust gas aftertreatment in compression ignition internal combustion engines. Background technique [0002] The usual exhaust gas aftertreatment systems used especially in compression ignition internal combustion engines reduce the NO present in the exhaust gas by means of a reducing agent X converted to H 2 O and N 2 . Common exhaust gas aftertreatment systems for compression ignition internal combustion engines work according to the principle of selective catalytic reduction (SCR), wherein the reducing agent used is in most cases a urea-water solution which is also by name A known. The exhaust gas aftertreatment system includes a storage tank in which a reductant capable of freezing is stored. The storage tank includes the filter, if necessary the filter cover and the tank heater as three separate components. In some systems, ...
