Embodiment Construction

[0041] figure 1 An ammonia storage cartridge 10 according to a first embodiment of the invention is shown.

[0042] Such a cartridge 10 is intended to be equipped in the exhaust system of a motor vehicle, in which ammonia is released.

[0043] The storage cartridge 10 includes an airtight container 12 within which is disposed an ammonia storage component 14 . The storage part 14 is made of a material capable of absorbing or adsorbing ammonia, which is called a storage material.

[0044] According to the described embodiment, the storage member 14 extends along the longitudinal axis X between the first end 15A and the second end 15B.

[0045] The storage material corresponds, for example, to one of the materials described in patent application WO2008 / 077652. Such materials are chosen, for example, from the series known as metalloamine complexes, having the general chemical formula M a (NH 3 ) n x z ,in:

[0046] M is one or more metals from the alkali metal group, such ...

Abstract

An ammonia storage cartridge includes_an ammonia storage member having a storage material capable of absorbing or adsorbing ammonia. The storage member extends along a longitudinal axis. A heating element heats the storage member, and a hermetic tank houses the storage member. A tubular ammonia circulation element is arranged coaxially to the storage member, and includes_a first surface at least partially delimiting, with an element chosen from among the heating element and the hermetic tank, a circulation duct for the fluid ammonia. A second surface is arranged at least partially in contact with the storage member, and-at least one orifice passes radially through, allowing the circulation of fluid between the circulation duct and the storage member.

Description

technical field [0001] The invention relates to an ammonia storage cartridge, in particular for use in a motor vehicle exhaust system. [0002] The ammonia storage cartridge is particularly useful for delivering ammonia to an engine, in particular a diesel engine, a lean-mix direct injection gasoline engine, or any lean-mix internal combustion engine. [0003] However, the invention is not limited to motor vehicle engines, but can also be applied to all types of internal combustion engines, in particular those of land, sea or air vehicles, or engines not equipped with vehicles. Background technique [0004] To reduce nitrogen monoxide and nitrogen dioxide emissions in the exhaust, ammonia is often injected into the exhaust system. Ammonia reacts with nitric oxide and nitrogen dioxide to form nitrogen and water. [0005] For safety reasons, ammonia is not stored in its natural form, but in the form of materials: usually made from metal chloride salts with ammonia absorbed o...
