    object
    The invention relates to an internal combustion engine with a series of Zy¬lindern in a cylinder block and a crankcase, which contains bulkheads between the cylinders with bearings for the crankshaft, wherein in the crankcase on either side of the cylinder each Ölverteilkanal is arranged in the longitudinal direction, by means of which pressure oil the Kurbelwellenlagemund other consumers is supplied. The other consumers are, for example, spray nozzles for the piston cooling.
    State of the art
    From DE 199 33 363 Al such an internal combustion engine is known. This has two Ölverteilkanäle, one on each side, which are connected via their own supply lines to the pressure side of an oil pump. This requires at least one pressure line attached to the outside of the cylinder block. The attachment usually takes place by means of a screw fitting whose sealing is problematic. The pressure pipes are labor-consuming to install and exposed.
    Alternatively, according to DE 100 24 207 A1, the connection between the two oil distribution channels could be made via branch channels to and from the crankshaft line. But this requires large cross sections of the channels in the bulkheads of the crankcase and the oil passage adapted crankshaft bearings. The thickness of the bulkhead walls determines the distance between the cylinders, which should be as small as possible.
    Troubleshooting
    It is therefore an object of the invention to provide an oil distribution within the Zylinder¬blocks, which ensures a good Ölversor-gung of all consumers with minimal manufacturing costs.
    According to the invention, the two oil distribution channels are fluidly connected to one another by transverse ducts extending in the bulkheads, which transverse seams are already produced during the casting of the cylinder block by correspondingly shaped core parts. This requires no installation effort and the Verbin¬dung the Ölverteilkanäle is absolutely tight and yet protected.
    In a further development of the invention, the oil distribution passages extend geodetically over the crankshaft journal and connect the transverse passages to the oil distribution passages in the shortest possible way. At this height, the channels are already in the vicinity of the cooling water jacket and thus cooled. Furthermore, the spray nozzles for Kolben cooling can be fed by the shortest route. There is also room for generously dimensioned distribution channels. The connection on the shortest path minimizes the flow losses.
    In a preferred embodiment, the transverse channels are produced during casting of the crankcase by attaching a respective core part in the casting mold and the cross sections of the transverse channels are changed over their length with the same cross-sectional area. Preferably, they are substantially circular in the parts adjoining the oil distribution channels and flattened in the transverse direction in the central region. In the middle region, the distance between the cylinder walls of the cylinder block is a minimum. It determines the length of the entire engine. The flattening carries the bill. Thanks to this, this distance does not need to be increased without creating a throttle in the cross channel. Because the transverse channel is determined by the shape of a core part inserted into the casting mold, the flattening does not cause any extra effort.
    Finally, in addition to the stub bores extending from at least one oil distribution channel to the crankshaft bearings, these can also originate from the second oil distribution channel. The situation is similar with the spray nozzles for the piston cooling. Anyway, so is provided for a plentiful and reliable oil supply.

    In the following the invention will be described and explained with reference to figures. They show:

    3 shows a cross section according to III-III in Fig. 1,

    description
    In Fig. 1, a cylinder block is denoted by 1 and a crankcase by 2. Both may be one-piece as in the present embodiment, but may be separate components bolted together. Similarly, here also a head part 3 with the cylinder block 1 in one piece. The center line of the at least two cylinders is denoted by 4. Each cylinder is formed by a cylinder wall 5 and a cooling water jacket 6. In between is a cooling water space 7.
    The crankcase 2 consists essentially of two-sided side walls 9 (see Fig. 2), end walls 12 and at least one bulkhead 8 between the respective cylinders. Below it ends here in a the center line 10 of the (not shown) crankshaft containing parting line 13, from which extend the upper halves 11 of the crankshaft bearings.
    In Fig. 2 are in the direction of the axis 10 extending Ölverteilkanäle 18,19 watch, a first 18 and a second 19. These are in Übergangsbei¬reich from the crankcase 2 to Zylinderblockl. In the case of a separate block Zy¬linderblocks they are in the crankcase 2, but in any case geodetically higher than the crankshaft axis 10, here in the lower region of the cylinder walls. 5
    In the illustrated embodiment, both sides of the lateral Kühlwasser¬mantels 14 each have a distribution channel 15 and a collecting channel 16 is provided for Kühlwas¬ser and connected via openings 17 with the cooling water space 7. The channels 15,16 here form the outer wall of the cylinder block 1. Bei konven ¬tioneller execution of the cooling jacket 14 would be the outer wall. The oil distribution channels 18, 19 are arranged directly below the channels 15, 16 through which cooling water flows. From the first oil distribution channel 18, a tap hole 26 (see Fig. 3) in the bulkhead 8 leads to the crankshaft bearing 11. A rib 21 in the bulkhead 8 allows a wide tap hole 26 without weakening the bulkhead 8. The second oil distribution channel 19 supplies (among other things) spray nozzles ¬sen 20 for piston cooling.
    Fig. 3 shows the connection of the two Ölverteilkanäle 18,19 on the shortest path by means of a transverse channel 23 with varied over its length cross-section.
    In the parts 24 adjoining the oil distribution channels 18, 19, the cross-section is circular and approximately the same diameter as the oil distribution channels 18, 19. The middle part 25 is flattened in the longitudinal direction. That is, it is narrow and tall at the cross section thereof, see also Fig. 25 in Fig. 1.
    This configuration of the cross section allows the course of the respective transverse channel 23 between the cylinder walls 5, where their spacing is a minimum because of the cylindrical contour of the cylinder walls 5. Because the transverse channel is made by molding a core part, in the outer wall (here, 22) are core holes closed with core plugs 27. From the first Ölverteilka¬nal 18, the tap hole 26 leads to the crankshaft bearing 11th
    In Fig. 4 only the various oil channels can be seen. From a not shownÖlpumpe a supply channel 30 leads to the first oil distribution channel 18. This is here (it is a motor with two cylinders) via the one Quer¬ channel 23 connected to the. From this leads a further supply channel 31 up to other consumers, the Ventilmecha¬nismus not shown and to an optionally existing turbocharger. From the first Öl¬verteilkanal 18 lead the tap holes 26 to the Kurbelwellelagem 11.Vom second Ölverteilkanal 19, the spray nozzles 20 are fed.
