Combined exhaust gas treatment/silencer device in an exhaust line of an internal combustion engine

摘要

The combined internal combustion engine exhaust gas re-treatment/sound damping arrangement has a sound damper (1) bounded by front and read end walls and a peripheral outer wall with at least one pre-oxidation catalyzer (5) and at least one re-treatment device. At least one exhaust gas re-treatment/sound damping module (7) is fitted in the sound damper as the core of the system.
