Embodiment Construction

[0022] according to figure 1 with figure 2 , the exhaust system of the internal combustion engine comprises a diesel particulate filter 12 through which a hot exhaust gas flow 13 flows during operation of the exhaust system, and an exhaust gas line 10 arranged downstream thereof. In this respect, the diesel particle filter 12 and the exhaust gas line 10 are arranged adjacent to each other such that their flow axes S1 , S2 run parallel. For connecting the diesel particle filter 12 to the exhaust gas duct 10 , the means for guiding the exhaust gas flow are provided in the form of a deflection housing 14 which delimits a first bend 18 and a second bend 19 . The two bends 18 , 19 each deflect the exhaust gas flow 13 by 90° and in the same direction. The deflection shell 14 is thus arranged to form a C-shaped channel in longitudinal section. In this respect, the inlet 16 of the deflection housing 14 is adapted to the outlet 31 of the diesel particle filter 12 . The outlet 15 o...

Abstract

A device for guiding a gas stream defines an inlet opening, an outlet opening and at least one angular offset which diverts the gas stream. The shell is assembled from a first shell part and a second shell part, wherein the first shell part defines the inlet opening and the outlet opening and has at least one connecting structure for the gas-tight connection of the device to a further gas-guiding component, and wherein the second shell part is configured to enclose the inlet opening and the outlet opening of the first shell part.

Description

technical field [0001] The invention relates to a device for guiding a flow of air, in particular of an exhaust gas of an internal combustion engine, comprising a housing delimiting an inlet, an outlet and at least one bend for deflecting the flow. Background technique [0002] Due to structural space constraints in modern motor vehicles it is often necessary to arrange the angle of the exhaust train at an angle, for which purpose the deflection housing described above is used. Such a deflection housing can be used in particular between two exhaust system components, for example between a particle filter and an exhaust gas line or between an exhaust gas line and a catalytic converter. [0003] Such gas guiding components are usually welded to upstream and downstream components of the exhaust train. Alternatively flanged connections can also be provided for welded connections. In this case, the flange belonging to the deflection device is welded to the housing. In this reg...
