Abstract
(DE) Die Erfindung betrifft eine Vorrichtung mit einem Abgasturbolader und einem dem Abgasturbolader in Strömungsrichtung nachgelagerten Ringkatalysator, wobei der Ringkatalysator eine erste rohrförmige Strömungsstrecke, einen Umlenkbereich und eine zweite ringförmige Strömungsstrecke aufweist, wobei die rohrförmige Strömungsstrecke durch ein Innenrohr gebildet ist und die ringförmige Strömungsstrecke zwischen einem im Wesentlichen parallel zum Innenrohr verlaufenden Außenrohr und dem Innenrohr gebildet ist und der Umlenkbereich zur Umlenkung der Abgasströmung aus der rohrförmigen Strömungsstrecke in die ringförmige Strömungsstrecke ausgebildet ist, wobei die rohrförmige Strömungsstrecke des Ringkatalysators bauteilgleich auch den Gasauslass des in Strömungsrichtung vorgelagerten Turboladers ausbildet.
(EN) The invention relates to a device comprising a turbocharger and an annular catalytic converter which is mounted downstream of the turbocharger in the flow direction. The annular catalytic converter has a first tubular flow section, a deflecting region, and a second annular flow section, wherein the tubular flow section is made of an inner tube, and the annular flow section is formed between an outer tube, which runs substantially parallel to the inner tube, and the inner tube. The deflecting region is designed to deflect the flow of exhaust gas out of the tubular flow section and into the annular flow section, and the same components of the tubular flow section of the annular catalytic converter also form the gas outlet of the turbocharger mounted upstream in the flow direction.
(FR) L'invention concerne un dispositif comprenant un turbocompresseur et un convertisseur catalytique annulaire monté en aval du turbocompresseur dans le sens d'écoulement. Le convertisseur catalytique annulaire présente une première section d'écoulement tubulaire, une zone de déviation, et une seconde section d'écoulement annulaire. La section d'écoulement tubulaire est constituée d'un tube interne, et la section d'écoulement annulaire est formée entre un tube externe, qui s'étend sensiblement parallèle au tube interne, et le tube interne. La zone de déviation est conçue pour dévier le flux de gaz d'échappement hors de la section d'écoulement tubulaire et dans la section d'écoulement annulaire, et les mêmes composants de la section d'écoulement tubulaire du convertisseur catalytique annulaire forment également la sortie de gaz du turbocompresseur montée en amont dans la direction d'écoulement.
