PROBLEM TO BE SOLVED: To provide an exhaust gas aftertreatment system for a vehicle operated by a combustion engine, for example a watercraft, by which the sulphur emission from the combustion engine are reduced in a particularly simple and effective manner.SOLUTION: The exhaust gas aftertreatment system comprises a turbine (29) of an exhaust turbocharger (19) arranged in an exhaust line (31) and a storage device (39). The exhaust line (31) is designed as a high-pressure region (32) upstream of the turbine (29) and as a low-pressure region (34) downstream of the turbine (29). With the storage device (39), at least some of the sulphur pollutants contained in exhaust gas (38) can be stored for a defined period of time. In the exhaust gas aftertreatment system according to the invention, particularly for storing the sulphur pollutants in the high-pressure region (32), the storage device (39) is arranged in the exhaust line (31) upstream of the turbine (29).SELECTED DRAWING: Figure 2
【課題】内燃機関により駆動される乗物、例えば水上乗物、のための排気ガス後処理システムにおいて、内燃機関の硫黄排出を極めて簡単かつ効果的に減少させる。【解決手段】排気ガスライン(31)内に配置された、排気ガスターボチャージャ(19)タービン(29)と蓄積装置(39)とが設けられ、排気ガスライン(31)は、排気ガス流動方向でタービン(29)上流では、高圧領域(32)として形成され、タービン(29)下流では、低圧領域(34)として形成されている。蓄積装置(39)により、排気ガス(38)中に含まれる硫黄汚染物質の少なくとも一部を、規定の期間にわたり蓄積可能である。本発明によれば、硫黄汚染物質を高圧領域(32)において蓄積するために、蓄積装置(39)は排気ガスライン(31)内でタービン(29)上流に配置されている。排気ガス後処理システム。【選択図】図2
