Exhaust gas system for internal-combustion engine of vehicle, has purification system with flow cross section formed as partial flow cross section of strand, where flow cross section of purification system is closable by closing element

摘要

The system (1) has an exhaust manifold (3) connected with an exhaust gas strand (4), in which an exhaust gas turbo charger (5) is arranged, where exhaust gas flows to the charger. An exhaust-gas purification system (6) is arranged in the strand between the manifold and the charger. A flow cross section of the purification system is formed as a partial flow cross section of the strand. The flow cross section of the purification system is closable by a closing element (7). The purification system and another exhaust gas purification system (11) exhibit a nitrogen oxides-storage coating.
