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 is for example from DE 40 07 939 C1 known. There is a separate manifold on the outside of this cylinder head attached, the several arranged 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. With such cylinder heads, it can in Depending on the installation position of the internal combustion engine, that does not happen the oil accumulating in the cylinder head is extracted under all operating conditions becomes. There is a risk that the lubricant supply to the Internal combustion engine may not have sufficient oil quantities from the circuit has available.
- Such a cylinder head for example, in the longitudinal direction of the motor vehicle installed, accumulates either when accelerating or Decelerate the oil on the side of the cylinder head facing away from the pump. As a result, the manifold may not be completely filled with oil, so that via the connections facing the pump to the interior of the Air is sucked into the cylinder head and the oil in the cylinder head is not extracted becomes. If such a cylinder head is installed transversely to the direction of travel, can for example, when cornering corresponding air sucked in Oil located in the cylinder head cannot be extracted.
- a cylinder head of an internal combustion engine with a device for returning lubricating oil from the interior improve that even with strong accelerations / decelerations or at When cornering, the oil collected in the interior of the cylinder head is sucked out and can be returned to the oil reservoir.
- a particularly safe oil extraction is advantageously ensured if the two manifolds at their ends 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 cylinder head shown in Figures 1 to 5 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.
- This cylinder head is composed of three housing components, a cylinder head basic housing 1, a camshaft housing 2 and a cylinder head cover 3.
- Das Cylinder head basic housing 1 has a lower flange surface 4, which is used for connection to serves the cylinder block or the crankcase, not shown.
- the upper Flange surface 5 of the cylinder head base housing 1 is with the cylinder head installed the lower flange surface 6 of the camshaft housing connected. Its upper Flange surface 7 is connected to the flange surface 8 of the cylinder head cover 3.
- the Camshaft housing 2 is used to accommodate tappets, not shown for actuating the gas exchange valves and at the same time contains the lower bearing caps for receiving the two camshafts, also not shown.
- the Camshaft housing 2 and cylinder head cover 3 enclose an interior 9, in which the camshafts described above rotate and in which are in operation the internal combustion engine from the bearings of the camshafts and Cup tappet collects escaping lubricating oil.
- This interior 9 is by two Longitudinal walls 10 and 11 in an upper part space 12 and a lower one in the installed position Subspace 13 separated. These subspaces 12 and 13 are each by the Storage chairs 14 divided in the longitudinal direction.
- transverse channels 15 are the upper part 12 and the lower part 13 connected to each other, so that Oil accumulating in the upper subspace 12 via the transverse channels 15 in the lower Subspace 13 can flow.
- This subspace 13 is in turn connected via transverse channels 16 a cast, in the longitudinal direction of the camshaft housing extending oil collection channel 17 connected.
- Two of the transverse channels 16 are included each arranged in the area of a storage chair 14, with their opening area in the interior 9 or the subspace 13 in both longitudinal directions over the width of the Bearing chair 14 extends.
- Three further transverse channels 16 connect the subspace 13 the manifold 17 in the middle of the cylinder.
- a further manifold 19 is formed on the lower longitudinal wall is also cast in the cast cylinder head cover 3.
- This The manifold 19 has a suction connection 20 which is connected to one of the two end walls 21 is arranged.
- this end wall 21 In the area of this end wall 21 is the one described here Embodiment of the chain case 22 formed for receiving or Cover of the control drive, not shown, is used.
- a bore 25 In the field of opposite end wall 23 is a bore 25 which is arranged by the Flange surface 8 starts and opens into the interior of the manifold 19.
- This Bore 25 is connected to an aligned bore 26 which is from the upper Flange surface 7 of the camshaft housing 2 starting in the manifold 17th empties.
- This manifold is also provided with a suction port 27, the is also arranged in the region of the chain case 22.
- the two suction connections 20 and 27 are each one with the suction side shown, known oil pump connected, which the extracted oil in the promotes also not shown oil reservoir of the internal combustion engine.
- the Suction can take place, for example, via two separate oil pumps, it is however, it is also possible to extract oil via a pump with two separate Make suction connections.
- the manifold 13 is connected in an analogous manner via the bores 25 and 26 filled.
- This arrangement of the manifold and the staggered arrangement of the Connections to the interior ensures that even with strongly fluctuating Oil levels in the interior of the cylinder head always at least one of the two Bus lines with their corresponding cross connection so with the interior is connected that the respective cross connection constantly below the oil level is located.
