Definitions

  • the invention relates to a cylinder head of an internal combustion engine with a device for returning lubricating oil from the interior of the cylinder head after Genus of the main claim.
  • a generic cylinder head in which one overhead camshaft is mounted.
  • the interior housing the camshaft is in the longitudinal direction of the cylinder head through transverse walls into individual subspaces divided. These transverse walls also form the camshaft bearing.
  • Each of these sub-rooms has an opening at the bottom of the Cylinder head housing trained manifold connected.
  • a cylinder head is also known in which - without that this is explicitly shown or described - two overhead camshafts are stored.
  • There is a separate manifold on the outside of the cylinder head is attached, which is arranged over several in the cylinder head and over the Longitudinal distribution of distributed bores is connected to the interior.
  • About these Bores will accumulate in the interior of the cylinder head, at the Lubricating oil escaping into the manifold from various bearing points via a pump and a return line with the oil reservoir of the Internal combustion engine is connected.
  • 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 up 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 appropriate Leakage problems or long holes with the corresponding effort in the Manufacturing are needed.

  • the middle subspaces 22A to 22C are bores 24 opening into the combustion chamber arranged to receive spark plugs or not shown Serve injectors.
  • the cylinder head cover 3 lies with its outer walls 25 to 28 on the Flange surface 7 of the camshaft housing 2.
  • the cylinder head cover has it in addition, two longitudinal webs 29 and 30 pulled down, sealing against the Longitudinal walls 10 and 11 rest.
  • the cylinder head cover 3 is designed such that he the camshafts 9, the cam circles and the bearing areas of the camshafts encompasses at a short distance.
  • Through this customized Contour of the cylinder head cover ensures that the gap 32nd between the camshaft bearings and the cylinder head cover as low as possible are.
  • the cantilevers 31 ensure that the Spaces 32 are angled in the longitudinal direction of the cylinder head, so that oil penetration is made difficult or largely prevented.
  • an oil collection channel 33 which is connected to the subspaces 23A to 23C is.
  • an opening 34, 35 is in each case in the region of the transverse walls 14 and 15 Outer wall 13 formed, the opening cross-section or their position and Extension in the longitudinal direction of the cylinder head is measured so that it with the neighboring subspaces 23A, 23B and 23B, 23C cooperate.
  • the Subspace 23A is additionally arranged in the area of the outer wall 18 Opening 36 connected to the manifold 33.
  • Another opening 37 connects the manifold 33 in the area of the outer wall 19 with the subspace 23C. So is each of the three compartments 23A to 23C via a front and a rear Transfer associated with the manifold.
  • a cast-in channel 38 formed, which bridges the middle subspaces 22A to 22C and the upper and connects the lower parts of the room.
  • These channels 38 are in their Cross-sectional shape or its location and extent in the longitudinal direction of the Cylinder head designed so that the arranged in the region of the transverse wall 14 Channel 38 the upper compartments 21A and 21B with the lower compartments 23A and 23B combines.
  • the channel 38 arranged in the region of the transverse wall 15 connects correspondingly, the upper subspaces 21B and 21C with the lower subspaces 22B and 22C.
  • a channel 39 connects the upper subspace 21A with the lower part 23A.
  • Another channel 40 in the area of the outer wall 19 connects the upper part space 21C with the lower part space 23C. So they are Subspaces 21A to 21C each via a front and rear channel with the lower Subspaces and connected to the manifold 33 via this.
  • This manifold 41 has a suction port 42, the is arranged in the region of the outer wall 26. In the area of this outer wall is at the embodiment of the chain case 43 described here, which for Includes or covers the control drive, not shown.
