Definitions

  • This invention relates to internal combustion engines, particularly to diesel engines that power motor vehicles.
  • the entrances of the cast-in goosenecks had circular cross sections at the reservoir. A certain minimum wall thickness and a corresponding amount of metal were needed at and adjacent those locations in order to endow the manifold with sufficient strength to assure that stresses in the metal did not exceed specified limits.
  • the inventors have discovered that a differently shaped entrance to a cast-in outlet tube from the reservoir can provide significant weight reduction without compromising compliance with the relevant specification for the oil manifold.
  • the inventors have confirmed this by comparative stress analysis. In a particular example, a weight reduction of about five pounds of iron was achieved.
