Title:
内燃機関の排気ガス流におけるアンモニア供給方法及び装置
Document Type and Number:
Japanese Patent JP2008542608
Kind Code:
A
Abstract:
A method for providing ammonia (NH3) in an exhaust gas flow of an internal combustion engine includes generating nitrogen monoxide (NO) with a plasma generator, reversibly storing at least a portion of the nitrogen monoxide (NO), reducing at least a portion of the stored and/or generated nitrogen monoxide (NO) to form ammonia (NH3) in a first gas flow, and mixing the first gas flow with the exhaust gas flow. The method and a device for reducing nitrogen oxides advantageously increase the efficiency of an on-board plasma-assisted generation of ammonia, particularly for mobile applications, such as in motor vehicles, and reduces the consumption of fuel required therefor, in comparison to prior art devices and methods.
