Exhaust gas guidance unit consists of exhaust collector pipe together with exhaust channel for transferring of exhaust gas to gas cleaning unit and exhaust gas return channel for return of exhaust gas to chambers within combustion engine

摘要

The exhaust gas guidance unit (1) comprises an exhaust collector pipe (2) that is feedable from many gas connections from many combustion chambers of the combustion engine. There is an exhaust channel (4) via which exhaust gas is transferable to an exhaust gas cleaning unit and/or to an exhaust gas turbo charger. There is an exhaust gas return channel (5) via which exhaust gas can be returned to one or more combustions chambers of the combustion engine. The exhaust collector pipe has an associated control valve, whilst there is a first blocking element (7) for blocking off the exhaust collector pipe against the exhaust gas return channel as well as a second blocking element (8) for blocking of the exhaust collector pipe against the exhaust channel. The first and second blocking elements are mounted about a common structure (9).
