Definitions
- the invention relates to a cylinder block of an internal combustion engine in open deck Construction according to the genus of the main claim.
- EP 0 137 328 A2 also discloses an open-deck cylinder block described, in which the connecting web on the lower, the crankcase facing end of the cylinder tubes is formed. An oil jacket is not intended. Ribs are provided in the cooling water jacket of this cylinder block extend over almost the entire height of the water jacket and to Influence the cooling water flow.
- the invention is based on the object, a cylinder block in to improve open-deck construction in such a way that in the assembled, clamped condition of the cylinder block or the cylinder tubes Cylinder tube distortions can be reduced or minimized.
- By arrangement of ribs in the water jacket is also particularly advantageous the influence on the cooling water flow is reduced. Be particularly effective Cylinder tube warpage avoided in that both in the oil jacket and in Water jacket ribs are arranged on the connecting web. It is still there an advantage if the ribs are in the cooling water jacket and in the oil jacket opposite.
- Such an improved connection of the cylinder tubes in cylinder blocks in open-deck construction is particularly suitable for standing alone, not with each other connected cylinder tubes.
- the cylinder tube distortions in the clamped state are particularly advantageous Minimized if the ribs on the connecting web in the area of Cylinder head screw connections are arranged.
- a radial course of the Ribs particularly cheap.
- the ribs follow the course of a Connection line between the axis of the cylinder head screw connection and the Following the cylinder tube axis is a clear one in a particularly advantageous manner Guaranteed reduction in cylinder tube distortion.
- the cylinder block 1 shown by way of example in FIGS. 1 to 3 has one Cylinder block housing 2 in which several cylinder tubes 3, 4, 5 as individual tubes, i.e. are not connected.
- the cylinder tubes 3 to 5 are over one connected connecting web 6 connected to the cylinder block housing 2.
- the connecting web 6 comprising all the cylinder tubes 3 to 5 separates the Clearance between the cylinder tubes and the cylinder block housing in one upper cooling water jacket 7 and a lower oil jacket 8.
- the cooling water jacket 7 encompasses the cylinder tubes 3 to 5 approximately in a ring and is on the upper side 9 the cylinder block, i.e. to the cylinder head, not shown, open.
- the Oil jacket 8 engages in an analogous manner the cylinder tubes 3 to 5 below the Connecting web 6 and is to the lower side 10 of the cylinder block, i.e. to the Crankcase 11 open.
- the cylinder block housing 2 is 3 to 5 per cylinder tube penetrated by four cylinder head screw connections 12.
- This Cylinder head screw connections 12 are used for fastening the not shown Cylinder head on the upper side 9 of the cylinder block and extend into one - Crankshaft bearing frame, not shown, which on the lower side 10 of the Cylinder block is attached.
- ribs 13 are formed per cylinder tube 3 to 5, which are connected to the connecting web 6. These ribs 13 are approximately triangular in shape and rise from the transition between the connecting web 6 and the cylinder tube 3 to 5 to the cylinder block housing 2.
- the four ribs per cylinder tube 3 to 5 are arranged so that they each run on the connecting line 28 between the axis 14 of the adjacent cylinder head screw connection 12 and the cylinder axis 15 of the cylinder tube.
- the height h 1 of the ribs 13 is significantly less than the height H 1 of the cooling water jacket 7. In this exemplary embodiment, it is approximately 1/3 of the height of the water jacket, but should at most extend into the middle of the water jacket, ie h 1 should be less than 0.5 x H 1 .
- the ribs 19 provide for an increased rigidity of the Cylinder block housing 2 and on the other hand enable a cylinder tube-related Cross-flow cooling within the cooling water jacket.
- ribs 22 are also arranged per cylinder tube 3 to 5, which extend in a triangular shape from the transition between the cylinder tube 3 to 5 and the connecting web 6 to the cylinder block housing 2. These ribs 22 are also arranged in the area of the cylinder head screw connections 12 and run radially to the respective cylinder tube axis 15. In this exemplary embodiment, the ribs 22 also lie in the oil jacket on the connecting line 13 between the axis 15 of the respective cylinder tube and the corresponding axis 14 of the cylinder head screw connection 12. Two further ribs 23 are arranged on the side opposite the ribs 16 in the cooling water jacket in the oil jacket.
- the height h 2 of the ribs 22 and 23 in the oil jacket is significantly less than the height H 2 of the oil jacket. In this embodiment, the height h 2 of the ribs 22 and 23 is approximately 1/4 of the height H 2 of the oil jacket.
- each two adjacent cylinder tubes 3, 4 and 4, 5th connect with each other.
- These additional, curved ribs 25, 26 each go from the connecting web 6 and extend to the vicinity of the lower ends 27 of the Cylinder tubes 3 to 5.
- These additional, curved ribs 25, 26 describe in the top view of an arch, the inside of the respective adjacent wall of the Cylinder block housing 2 faces.
