Abstract
An exhaust gas collecting and cleaning device for a multi-cylinder engine comprising an exhaust-gas manifold (1) constructed as a casting and an exhaust-gas cleaning device (5) mounted near the engine, attached to the exhaust-gas manifold (1) and comprising a housing (6) and at least one exhaust-gas cleaning element (14) bedded therein. A tubular section (12), which is constructed as a sheet-metal part and projects from the casting, is cast into the exhaust-gas manifold (1) at the outlet end region thereof. To this there is joined a downstream segment of the housing (6) of the exhaust-gas cleaning device (5). According to an independent embodiment, a downstream exhaust-gas guide element (such as a corrugated pipe) instead of the exhaust-gas cleaning device is joined in corresponding manner to the exhaust-gas manifold constructed as a casting.
