Abstract (en)
[origin: EP0748928A1] The exhaust manifold (1) has inlet tubes (2, 3, 4), forged from a sheet, and leading from an engine's cylinder head outlets (5, 6, 7) to a common exhaust pipe (8). It includes bent inlet tubes (2, 4) which themselves consist of at least two single bent tubes (2a, 2b, 4a, 4b). These single tubes may be of varying cross section along their length, with continuous transition. The overall cross section of the single tubes in each longitudinal sector is basically the same as that of the corresponding inlet tube. The bends in the single tubes are of about 90 degrees .
