SCR exhaust gas aftertreatment device

Номер: US8875502B2
Принадлежит: Cummins Ltd

An SCR exhaust gas aftertreatment device in which a urea-water solution is injected into an exhaust gas line is provided. At least one component of the device (e.g., a filter element) lies in an area of an internal space, and is bounded by an elastomer membrane that is embedded in a frost equalization foam. This prevents freezing damage even over a very long period of time and a large number of freezing cycles.

Fluid delivery system for exhaust aftertreatment system

Номер: US10100697B2
Принадлежит: Tenneco Automotive Operating Co Inc

A fluid delivery system for an exhaust aftertreatment system may include an outer housing, a pump, a filter assembly, an electric heating blanket, and a heater retention plate. The heater retention plate is shaped to correspond to the shapes of the pump and filter assembly. A lid of the outer housing contacts the heater retention plate and clamps the heating blanket between the heater retention plate and the pump and filter assembly so that the heating blanket takes the shapes of portions of the pump and filter assembly. The outer housing includes mounting flanges and reinforcement members extending from corresponding mounting flanges to corresponding sidewalls of the outer housing and forming a hollow space therebetween. The filter assembly includes compensation elements that contract in response to expansion of fluid within a pump housing due to freezing and expand in response to thawing of the fluid.

Process and device for introducing a fluid into an exhaust gas purification system

Номер: WO1996008639A1
Принадлежит: SIEMENS AKTIENGESELLSCHAFT

The nitrogen oxides emitted by an internal combustion engine operated with excess air are normally converted by the selective catalytic reduction process, that is, by bringing them into contact with ammonia on a selective catalyst. In a vehicle, the dangers associated with the use of ammonia demand that it be carried only in the form of an ammonia-releasing substance, generally an aqueous urea solution. The present invention solves the problem of preventing frost damage to parts of the exhaust gas purification system when the vehicle is not running and of facilitating the operation of such systems at temperatures below the freezing point of the reducing solution used. To that end, it is proposed that the system (2) should comprise a (thermally insulated) reservoir (6) for the reducing fluid (4) and, connected thereto, a fluid feed duct (12) which ends in an outlet aperture (22) for the fluid (4). The reservoir (6) and fluid feed duct (12) can be heated. In addition, a heating element (38) is provided for the purpose of liquefying an initial volume (14) which is smaller than the volume of the reservoir (6). The fluid feed duct (12) can also be provided with a reverse flush valve (20) which can be actuated by a pressurised gas (30), thereby allowing the said fluid feed duct (12) to be cleared by blowing.

Frost-resistant liquid pressure sensor for exhaust reducing systems (diesel engine)

Номер: EP1664713B1
Принадлежит: Hydraulik Ring GmbH

The invention relates to pressure sensors for exhaust reducing systems, in particular, of diesel engines. These pressure sensors have a housing (61) inside of which a measuring cell is housed. The pressure of the exhaust reducing medium, which can freeze at low temperatures, is measured by a pressure sensor (63). When freezing, the medium expands whereby damaging the measuring cell housed inside the housing of the pressure sensor. In order to prevent the pressure sensor from being damaged when the exhaust reducing medium freezes, a compressible volume (bellows 68) is located between the measuring cell and the supply line for the medium. This compressible volume accommodates a change in volume of the exhaust reducing medium when it freezes or the measuring cell is mounted on a deformable part so that the measuring cell can be elastically displaced in the event of a change in volume of the exhaust reducing medium due to freezing. As a result, the volume expansion of the medium during a freezing process does not disadvantageously act upon the measuring cell. The pressure sensor is used for exhaust reducing systems in diesel engines of motor vehicles (urea/water solution).
