DEVICE AND METHOD FOR PROCESSING NITROGEN OXIDES CONTAINED IN EXHAUST GASES

摘要

The invention relates to a device for processing exhaust gases generated by the internal combustion engine of an automobile, including an exhaust line with an ammonia reduction catalytic converter (11) and an injector for an ammonia precursor or for a reducing agent capable of forming an ammonia precursor, mounted upstream from the reduction catalytic converter (11). The device further includes a static mixer (13) mounted between the injector (12) and the reduction catalyst (11), said static mixer (13) including a catalytic converter for forming ammonia from the ammonia precursor.
