Exhaust assembly of a combustion engine with several catalytic converters in the exhaust tract

摘要

The system has a hydrolysis catalyzer (8) that is attached with an oxidation catalyzer (7) in a common housing (11). An exhaust gas component string (3) with a tubular section (3a) encompasses a tubular section (4a) of an exhaust gas component string (4). A ring-shaped inflow area (12) serves as a heating chamber for the oxidation catalyzer. A reduction agent is injected in the tubular section (4a) of the exhaust gas component string (4), and ammonia is produced by using the hydrolysis catalyzer.
