Abstract

The invention relates an arrangement for the mounting of exhaust gas lines which are arranged in an exhaust gas-tight space, and serve for the transfer of the combustion gases from the exhaust openings of the cylinder heads to the exhaust gas manifold. By reason of the high temperature load of the exhaust gas lines which are not cooled in the exhaust gas-tight space, the mounting is so constructed that no compulsory forces can occur which stem from the temperature strain. This is achieved by a point-shaped mounting of flanges connected with the exhaust gas lines at only one circumferential place each. The single point fastening assures a radial and axial expansion possibility of the exhaust gas lines under thermal load free of compulsory forces. The exhaust gas lines are threadably secured each by means of fastening bolts within the area of the ends of the cylinder head side preferably at the cylinder head or at wall parts of the components forming the exhaust gas-tight space. The fastening by means of bolts is safe and space-saving.
