摘要：The invention relates to an exhaust gas manifold of diesel engines with 9 or 18cylinders, with nine linearly arranged and progressively numbered cylinders (1 to 9) perrow, with a compound exhaust gas manifold (17) which extends along the cylinders and, inthe case of an ignition sequence of the cylinders (1, 7, 4, 2, 8, 6, 3, 9, 5, 1) has an outlet to aturbocharger (10) at the end near to the first cylinder and a sealing cover (11) at the endnear to the last cylinder while, in the case of a reverse ignition sequence of the cylinders(1, 5, 9, 3, 6, 8, 2, 4, 7, 1) it has an outlet to a turbocharger (10) at the end near to the lastcylinder and a sealing cover (11) at the end near to the first cylinder. Specifically in thecase of nine cylinders per row, the gas expulsion of one cylinder coincides with the

scavenging procedure of the cylinder preceding it by two ignitions. The most dangerouspressure peaks, caused by reflection against the sealing cover (11), are smoothed by arestriction (12) in the exhaust gas manifold (17) whose cross-section of passage has anarea of 40 to 60 % of the adjacent cross-section of the exhaust gas manifold (17), themean pressure between the sealing cover (11) and the restriction (12) rising by about 0.1bar. Overall, design advantages and low investment costs for the turbocharger (10) areobtained.
