EXHAUST SYSTEM FOR AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to an exhaust system (1) for an internal combustion engine (2), especially a diesel engine, comprising an exhaust manifold (3) inside which at least one exhaust aftertreatment apparatus is disposed, and at least one DeNOx unit that is arranged downstream from a first oxidizing catalyst (4).
