Definitions
- the invention relates to an internal combustion engine with liquid cooling with at least one cylinder block and at least one cylinder head for at least two cylinders, wherein the internal combustion engine has a first side and an opposite second side of a longitudinal center plane spanned by at least two cylinder axes of the cylinder and in at least one web region between two adjacent ones Cylinders in the region of a normal to the longitudinal center plane arranged engine transverse plane in the cylinder head at least one first and the second side connecting second cooling channel is arranged with at least a first opening on the first side and at least one second opening on the second side.
- Cylinder blocks with such cooling channels in the cylinder head are known from DE 10 2005 033 338 AI.
- the cooling channel is formed as a groove, ie as an open cross-sectional shape in the region of the cylinder head density level, and produced by sawing or milling.
- the disadvantage of this design is the space required for this cooling groove and the resulting elaborate cylinder head gasket.
- the second cooling channel between the first and the second opening is formed as a closed cross-section in the cylinder head and from a cylinder head sealing plane of the cylinder head at least in the region of the longitudinal center plane in the direction of a cylinder axis has a sealing plane spacing.
- Closed cross sections can be formed by drilling, casting or spark erosion into the cylinder head, for example.
- An advantageous embodiment variant results if-measured in the region of the longitudinal center plane in the direction of the cylinder axis-the sealing plane distance between the second cooling channel and the cylinder head density plane corresponds to at least a smallest wall thickness of a fire deck of the cylinder head in the region of a combustion chamber. This ensures that the space savings can be really achieved without the wall thicknesses are too small to guarantee the mechanical strength.
- the second cooling channel is at least partially performed increasing from an area of the fire deck of the cylinder head, preferably starting from the cylinder head density plane in the direction of the longitudinal center plane, since the engine length compared to a design without cooling channels in the cylinder head relatively little longer or the same length is.
- the second cooling channel has at least a first sub-channel and at least a second sub-channel, the first sub-channel on the first side starting from the first opening in an area of the fire deck of the cylinder head, preferably from the cylinder head sealing plane in the direction the longitudinal center plane is rising and the second sub-channel runs on the second side, starting from the second opening in an area of the fire deck of the cylinder head, preferably from the cylinder head density plane in the direction of the longitudinal center plane.
- first sub-channel and the second sub-channel - preferably in the region of the longitudinal center plane - are interconnected in the region of an intersection of the sub-channel axes, wherein preferably the intersection of the sealing plane distance is removed from the cylinder head density plane ,
- the point of intersection can also be arranged outside the longitudinal center plane.
- the first part of the first opening to a substantially arranged on the second side of the second partial cooling chamber of the cylinder head is running and / or that the second sub-channel of the second opening to a substantially arranged on the first side of the first partial cooling chamber of the cylinder head is running running.
- a third partial channel is provided between the first partial channel and the second partial channel, which is preferably parallel to the cylinder head density plane.
- a particularly advantageous embodiment variant results if the first opening opens into a first partial cooling jacket space of the cylinder block arranged on the first side and / or that the second opening opens into a second partial cooling jacket space of the cylinder block arranged on the second side.
- any configuration of the second cooling channel is obtained when at least one second cooling channel is formed in the cylinder head by drilling or by molding in a casting or by spark erosion.
- the cooling channels can also have more complex cross-sectional shapes, such as a triangular shape, and by pouring virtually any cooling channel curves can be formed, for example by salt cores.

- the cylinder block 40 has four cylinders 41, partially shown in FIG.
- cylinder head 10 is shown in a first embodiment in a section along the line II-II in Fig. 1, with four each one of the cylinder 41 associated combustion chambers 2.
- a longitudinal center plane 27 is defined by at least two cylinder axes 46 (see FIG 11) the cylinder 41 is clamped; in the illustration in Fig. 2, the longitudinal center plane 27 extends vertically to the page level.
- the internal combustion engine 1 and thus also cylinder head 10 and cylinder block 40 have a first side 4 and a second side 5, which represent the opposite sides of the longitudinal center plane 27.
- a web portion 12 can be seen.
- this web region 12 in the region of a normal to the longitudinal center plane 27 arranged engine transverse plane 3 is a second cooling channel 13.
- the second cooling channel 13 extends in a first partial channel 16 in a first opening 31 from a first side 4 of a fire deck 17 and is connected to the first rising line 14 on this first side 4 flow-connected.
- the flow connection between the first partial channel 16 and a second riser 44 of a second partial cooling jacket space 45 of the cylinder block 40 arranged on the second side 5 produces a second partial channel 18 which likewise starts from the fire deck 17 in a second opening 32.
- the fire deck 17 is located in the area of the cylinder head density plane 11 and encloses all freely accessible areas of the cylinder head 10 from the cylinder head density plane 11.
- the second cooling channel 13 consists of two sub-channels 16, 18, which approach more and more, the farther they - in the direction of a cylinder axis 46 (ie from the sheet plane in FIG. 3) - remove from the fire deck 17.
- the first partial cooling space 15 and a second partial cooling space 19 are shaped in the embodiment shown so that they partially lead around bores 20 for cylinder head screws, not shown, as shown in FIG. 4.
- Each cylinder 41 has two first gas channels 21, for example inlet channels and two second gas channels 22, for example outlet channels. Between these and the combustion chamber 2 are the gas exchange valves, not shown, whose valve seats 23 can be seen in Fig. 4.
- the first side 4 and second side 5 of the internal combustion engine 1 designate the inlet side and the outlet side in the present embodiments.
- the first part of the cooling chamber 15, the first riser 14 and the first gas passage 21, as well as the first Partkühlmantelraum 43 are located on the first side 4 of the internal combustion engine 1.

- This third sub-channel 28 extends parallel to the cylinder head density plane 11 in the embodiment shown.
- the third sub-channel 28 is inclined at an angle to the cylinder head sealing plane 11 and thus the first sub-channel 16 and the second sub-channel 18 of the second cooling channel 13 fluidly connected to each other.
- the third sub-channel 28 allows for long distances between inlet side and outlet side not too low angle of attack for a drilling tool in the manufacture of the sub-channels 16, 18.
- the third sub-channel 28 may be formed by lost cores in a casting process or through a hole. If the third sub-channel 28 is formed by a bore, the unwanted flow connection is prevented to the outside with not shown closures.
- the second cooling channel 13 may be formed for example by spark erosion.
- cooling channels in the illustrated embodiments extend substantially in or parallel to the engine transverse plane 3
- variants are also possible in which the channels in the web region 12 are inclined to the engine transverse plane.
