Definitions

  • the invention relates to a hood covering the space between V-shaped rows of cylinders of an internal combustion engine according to the preamble of claim 1, as is known for example from DE-C-36 35 478.
  • DE-C-36 35 478 shows the design of a housing which gas-tightly encloses the pitot tube of an internal combustion engine and the fuel gases from the cylinder heads to the pitot tube.
  • the cooled housing is located in the space between the cylinder rows of the internal combustion engine, which are arranged in a V-shape.
  • the housing consists of a lower part and an upper part, the latter of which has contact surfaces both on the cylinder heads and on the crankcase.
  • the contact surfaces on the cylinder heads must be sealed by ring seals between the cylinder heads and the upper housing part, and furthermore the upper part of the housing must be provided with a cover.
  • the invention has for its object to ensure the sealing of a space covered by a hood between two rows of cylinders of a V-engine without requiring special requirements on the manufacturing tolerances, or requiring a particularly high elasticity of the seals, and to achieve a good Sealing still no high forces have to be introduced in unfavorable areas of the engine.
  • the Pitot tube 5 like the exhaust gas lines 6 transferring the fuel gases from the cylinders 4 to the Pitot tube 5, is arranged in an exhaust gas-tight space in the region between the cylinder rows.
  • the exhaust gas-tight space is formed by corresponding walls of the crankcase 7 and a hood covering the crankcase 7.
  • the hood covering the space is formed from a central hood part 2, which rests on the crankcase 7, and wedge-shaped hood parts 3, which are designed as pipe elbows and connect the cylinder heads 10 to the central hood part 2.
  • the end faces of the hood parts 3 lie sealingly on the central hood part 2 and on the cylinder heads 10.
  • Ring seals 8 and 9 are arranged in the contact surfaces to compensate for shape tolerances. One of the ring seals can also be dispensed with.
  • the hood parts 3 are screwed to the crankcase 7 with two screws 11 each with high expansion capacity, for example expansion screws.
  • the hood parts 3 can compensate for positional tolerances and heat distortion by changing their height.
  • the sealing effect is independent of the position tolerances.
  • the forces with which the sealing surfaces of the wedge-shaped hood parts 3 are pressed against the central hood part 2 and the cylinder heads 10 thus depend solely on the expected heat distortion of the internal combustion engine and not on positional tolerances.
  • the forces introduced by screws 11 into the motor structure are correspondingly low. Because the heat distortion of the Motors is taken up by the screws 11 with displacement of the wedge-shaped hood parts 3, sealing elements with low expansion capacity, for example graphite seals, can be used which are resistant to high temperatures.
  • the compensation of shape tolerances on the central hood part 2 can be carried out by a seal 12 in the support on the crankcase 7. Positional tolerances have no influence on the seal.
  • the hood parts 3 resting on the central hood part 2 additionally increase the contact pressure of the hood part 2 on the crankcase 7. The sealing effect between the crankcase 7 and the hood part 2 is thereby increased.
  • the force exerted by the hood parts 3 on the central hood part 2 can be taken into account when designing the number of fastening screws for the central hood part 2.
  • Another advantage is that only lateral forces are introduced into the cylinder heads due to the attachment of the hood parts 3 with screws 11 in the crankcase 7. Since the contact forces are limited and are distributed over the contact surfaces, there is no risk of undesired deformation, particularly in the area of the liners.
