Diesel motor exhaust gas cleaning assembly has a selective catalytic reduction catalyst unit with leading oxidation catalysts and a trailing fuel vapor injector and particle filter

摘要

The assembly (1) to clean the exhaust gas from an internal combustion motor (2), especially a diesel motor, has at least one selective catalytic reduction (SCR) catalyst unit (14) in the exhaust gas flow. At least one oxidation catalyst (12,13) is in front of it using a reduction agent to convert specific gas components especially to ammonia (NH 3) for SCR. At least one particle filter (18) is after the catalyst assembly. A dosing unit (20) injects fuel vapor in front of the particle filter at given times and in set volumes.
