Exhaust gas evacuation for commercial motor vehicle, has front exhaust silencer between frame longitudinal bar and drive, and main exhaust silencer with SCR-catalyst follows former silencer exhibiting hydrolysis and oxidation catalyst

摘要

The evacuation has an exhaust collecting pipe (4.1, 4.2) connected with a turbine (5.1, 5.2). The exhaust pipe guides a front exhaust silencer (8) between a longitudinal bar of a chassis frame and a drive (16). The silencer internally exhibits a hydrolysis catalyst (10) and an oxidation catalyst (9). A main exhaust silencer (13) with an integrated SCR-catalyst downstreamly follows to silencer (8).
