Abstract

Um eine Abgasanlage (100) für einen Verbrennungsmotor mit einem Außengehäuse (10), in welches ein heißes Abgas (31) durch einen Abgaseinlass eingeleitet wird und aus einem Abgasauslass (12) ausgeleitet wird, wobei der Abgasauslass (12) röhrenförmig, insbesondere mit einem kreisrunden oder ovalen Querschnitt, ausgestaltet ist, bereitzustellen, die auf einfache Art und Weise möglichst effektiv die Abgastemperatur im Abgasauslass senkt, wird vorgeschlagen, dass im Bereich des röhrenförmigen Abgasauslass (12) ein Abgasverwirbler (20) angeordnet ist, der zumindest eine Leitschaufel (23) aufweist, wodurch das Abgas (31) im Abgasauslass (12) abgelenkt wird.

Figure imgaf001
To an exhaust system (100) for an internal combustion engine having an outer housing (10) into which a hot exhaust gas (31) is introduced through an exhaust gas inlet and from an exhaust gas outlet (12), wherein the exhaust gas outlet (12) tubular, in particular with a circular or oval cross-section, configured to provide the exhaust gas temperature in the exhaust outlet as effectively as possible low, it is proposed that in the region of the tubular exhaust outlet (12) an exhaust swirling device (20) is arranged, the at least one guide vane (23 ), whereby the exhaust gas (31) is deflected in the exhaust gas outlet (12).
