  • In the oil-bearing interior of the cylinder head relatively large amounts of oil are carried, which at the bearings of the camshafts and the tappet or valve lever should come out.
  • the invention is therefore based on the object of a cylinder head Internal combustion engine with a device for returning lubricating oil from the To improve the interior so that the free oil in the interior as little as possible foamed and quickly reached the suction point.
  • the amount of oil freely located in the interior of the cylinder head can be kept low and the accumulation of large amounts of oil in the interior Accelerations / decelerations and / or cornering can be avoided.
  • Such a partitioning of the interior can be particularly advantageous take place when the bearing sections for receiving the camshafts as transverse walls be trained and consistently to the adjacent side walls are led.
  • the camshaft bearing and transverse wall function there is sufficient space for partitioning the interior Housing the cams and the stroke transmission elements, for example Cup tappet or valve lever.
  • the space can particularly advantageous way as an oil-free space for receiving a spark plug or an injector can be used.
  • a foreclosure not only achieved the advantages described above with regard to the oil flow, in addition, a very rigid structure of the cylinder head is made possible.
  • a particularly safe oil extraction is advantageously ensured if the two manifolds at their end facing away from the suction point are connected. Collects in such a cylinder head due to Accelerations the oil in the cylinder head essentially in the range this connection point, the oil in the first manifold can also be sucked off via the connection of the two manifolds.
  • the manifolds can be particularly advantageous and inexpensive Manufacture if these are cast in with cast components of the cylinder head be, so that neither external lines, screw connections with corresponding Leakage problems or long holes with the corresponding effort in the Manufacturing are needed.
  • the cylinder head shown in Figures 1 to 4 is not limited to this Exemplary embodiment as one of the two cylinder heads of a 6-cylinder boxer engine shown, which is installed in the longitudinal direction of the vehicle.
