Exhaust-gas system for combustion engine, particularly for leanly operated internal combustion engine, has two exhaust gas cleaning systems, where one exhaust gas cleaning system is arranged closely to combustion engine

摘要

The exhaust-gas system (1) has two exhaust gas cleaning systems (2,3), where one exhaust gas cleaning system is arranged closely to a combustion engine. Another exhaust gas cleaning system is arranged distantly to an internal combustion engine. The exhaust gas cleaning system and a sound absorber (4) are connected together with an exhaust-gas pipe (5). Both the exhaust gas cleaning systems are connected together in a gas-carrying manner with another exhaust-gas pipe (6), which is arranged in an inner volume of the exhaust-gas pipe.
