Abstract: An exhaust gas duct for a row of a plurality of combustion engine cylinders has an exhaust pipe section extending alongside the cylinders and a cooling housing in which the exhaust pipe section is mounted. The cooling housing has a middle longitudinal section and two end sections, one of which is a cover and the other is a mounting connector duct end ring. The middle section has substantially circular end portions with cooling liquid flow ducts therein and a flange portion for mounting to a cylinder head. The middle section is made of extruded standardized stock of light metal which facilitates the manufacture and assembly of the duct. A compact structural volume is also achieved thereby. The extruded stock material assures a good dimensional accuracy, a high surface quality, and good sealing characteristics.
