Exhaust gas duct for a row of cylinders of an internal combustion engine

An exhaust gas duct for a row of cylinders of an internal combustion engine, comprising a single piece exhaust gas pipe section for extending alongside said row of cylinders, said exhaust pipe section having a first open end and a second closed end, a cooling housing wherein said exhaust gas pipe section is mounted, an insulating gap between said cooling housing and said pipe section, said cooling housing comprising an elongated housing section and first and second housing end sections for closing said elongated housing section, cooling liquid flow channels (15) in said cooling housing, exhaust gas flow passages (20) through said exhaust gas pipe section and through said cooling housing, said exhaust gas pipe section being self-supporting between its ends for mounting said ends of said exhaust gas pipe section in said housing end sections, whereby said exhaust gas pipe section is unsupported between its ends along said insulating gap, first means for mounting said first end of said exhaust gas pipe section in said first housing end section, and second means for mounting said second end of said exhaust gas pipe section in said second housing end section, at least one of said first and second mounting means permitting an axial displacement of said exhaust gas pipe section relative to said cooling housing in response to thermal expansions and contractions of said exhaust gas pipe section.
