Device for reducing nitrogen monoxide and nitrogen dioxide emissions in the exhaust fumes of a combustion engine

[0034] exist figure 1 In , an apparatus 10 for reducing nitrogen monoxide and nitrogen dioxide emissions in the exhaust of an internal combustion engine, such as a motor vehicle engine, is shown. In particular, the internal combustion engine is equipped with an exhaust line 11 through which the exhaust gas is discharged.

[0035] In order to reduce the nitrogen monoxide and nitrogen dioxide emissions in these exhaust gases, ammonia is injected into the exhaust line 11 to react with these exhaust gases.

[0036] For this purpose, the reduction device 10 includes at least one ammonia storage cartridge 12 . For example, the reduction apparatus 10 typically includes three storage drums, specifically one initial drum 12B and two main drums 12 , the initial drum 12B typically being smaller in size (in particular length) than the main drum 12 .

[0037] Each storage cartridge 12, 12B includes a sealed canister in which the ammonia storage member 14 is housed. The ammonia storage m...
