    • An injection nozzle for diesel engines is disclosed with a direct fuel injection into combustion air in the combustion space having a swirl. The nozzle is constructed as a hole-type nozzle with several injection openings arranged at uniform distances and distributed along the nozzle circumference. In order to further develop such an injection nozzle in a manner which permits shorter injection durations and an improved utilization of the air, an additional injection opening with a smaller diameter is constructed in each case between two adjacent larger injection openings, whereby the overall cross-sectional surface of all injection openings becomes larger without any drifting into one another of the thus formed fuel sprays.
    • 公开了一种用于柴油发动机的喷嘴,其具有直接燃料喷射到具有漩涡的燃烧空间中的燃烧空气中。 喷嘴被构造为具有多个喷射开口的孔型喷嘴,喷射孔以均匀的距离布置并且沿着喷嘴周边分布。 为了进一步开发这种注射喷嘴,其允许更短的喷射持续时间和改善的空气利用率,在两个相邻较大的喷射开口之间的每一种情况下构造具有较小直径的附加喷射开口, 所有喷射开口的截面表面变大而不会因此形成的燃料喷射物彼此漂移。

    • 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.
