PCT No. PCT/DE89/00404 Sec. 371 Date Mar. 13, 1990 Sec. 102(e) Date Mar. 13, 1990 PCT Filed Jun. 19, 1989 PCT Pub. No. WO90/00673 PCT Pub. Date Jan. 25, 1990.A hood covering the space between cylinder banks of an internal-combustion engine which are arranged in a V-shape is provided for the gastight enclosure of a ram pipe arranged in an area between cylinder banks and exhaust pipes leading the fuel gases from the cylinders to the ram pipe. At this type of a hood, sealing surfaces are obtained with respect to the crankcase as well as with respect to the cylinder heads. The hood can be constructed with a central hood part which is fastened to the crankcase and only has contact surfaces with respect to the crankcase, but not with respect to the cylinder heads. Wedge-shaped hood parts, which are constructed in the form of elbows, are arranged in a V-shaped opening between the central hood part and the cylinder heads and are pulled into the V-shaped opening by means of necked-down bolts. Common sealing surfaces exist with the cylinder heads and the central hood part. Positional tolerances are compensated by the fact that the wedge-shaped hood parts take up a corresponding position. For this reason, the forces, by which the sealing surfaces must be presses against one another, are dependent only on the expected thermal warping. The forces introduced into the engine structure are therefore also correspondingly low.
