Abstract (en)

[origin: EP1172534A2] Exhaust gas elbow (1) comprises a single exhaust gas outlet (2) with an outlet fixing flange (3) and at least two exhaust gas inlets (4, 5, 6) with an inlet fixing flange (7) for fixing to an engine block of a motor vehicle. The exhaust system of the exhaust gas elbow is formed between the inlet fixing flange and the outlet fixing flange by a single-walled cowl (8) forming the collecting pipe. The cowl surrounds all the exhaust gas inlets. Preferred Features: The cowl has a closed radial flange or a radial extension (9) on the side of the exhaust gas outlet which is connected to the outlet fixing flange preferably by a welded joint (14) so that it is gas-tight. The cowl has a radial flange or a radial extension (10) on the side of the exhaust gas inlets and surrounding the exhaust gas inlets which is connected to the inlet fixing flange preferably by a welded joint (15) so that it is gas-tight.
