    The invention relates to a liquid-cooled internal combustion engine with at least one cylinder block, which is connected to at least one cylinder head, with at least one first cooling jacket in the cylinder block and at least one second cooling jacket in the cylinder head, wherein the first and the second cooling jacket arranged in a coolant circuit and flow-connected to each other, and with at least one arranged in the coolant circuit actuator.
    DE 103 06 695 A1 discloses an internal combustion engine having a coolant circuit, which has a first cooling line for a crankcase and a second cooling line for a cylinder head. The coolant circuit has a leading to the first cooling line branch line, in which a shut-off is arranged. A second branch line of the coolant circuit is arranged parallel to the first branch line and leads, bypassing the obturator, to the first cooling line. When the obturator is closed no coolant enters the cooling jacket of the crankcase, only the cooling jacket of the cylinder head flows through it. When the shut-off device is open, however, a part of the coolant enters the cooling jacket of the cylinder head and another part in the cooling jacket of the cylinder housing, wherein the coolant flows from the cooling jacket of the crankcase provided in the cylinder head gasket transitions between the crankcase and the cylinder head into the cooling jacket of the cylinder head , and wherein the coolant flows are combined in the cylinder head.
    A disadvantage is that in DE 103 06 695 Al the flow field in the cooling jacket of the cylinder head and thus its cooling conditions, especially in the area of the entire fire deck, changes at different positions of the obturator, because the inflow - in particular the flow direction and the distribution of the coolant - change significantly.
    The object of the invention is to avoid these disadvantages and to achieve the same flow conditions in the cylinder head in each operating range of the internal combustion engine.
    According to the invention this is achieved in that the actuator is formed by a switching device which blocks in a first switching position a bypass flow path for the first cooling jacket and opens a coolant inlet of the first cooling jacket, so that in the first
    Shift position, the entire coolant is passed in series through both cooling jacket, and which blocks the coolant inlet of the first cooling jacket in a second switching position and opens the bypass flow path for the first cooling jacket, so that in the second switching position, the total amount of coolant, bypassing the first cooling jacket only by the second Cooling jacket is passed.
    Total coolant quantity here means the entire amount of coolant supplied to the cylinder block or discharged from the cylinder head minus a quantity of coolant escaping directly through at least one possible vent directly between the first and second coolant jacket. The amount of coolant flowing through the degassing opening (s) is approximately 5% of the total quantity of coolant supplied to the cylinder block or discharged from the cylinder head.
    Characterized in that the coolant in the first switching position flows through the first and the second cooling chamber in succession, the flow directions in each operating range of the internal combustion engine are the same.
    This also applies in intermediate positions of the switching device. In intermediate positions of the switching device, both the coolant inlet of the first cooling jacket, as well as the bypass flow path of the first cooling jacket partially open, so that a portion of the coolant through the first cooling jacket and another part of the coolant through the bypass flow path, bypassing the first cooling jacket is passed. The entire coolant also flows through the second cooling jacket.
    In each switching position of the switching device, the second cooling jacket can be flowed through by the entire coolant flow supplied through the main inlet. In each position of the switching device, the same flow field forms in the second cooling jacket of the cylinder head. Regardless of the position of the switching device thus the flow of the fire deck remains unchanged. The entire amount of coolant always flows through the same access and in the same quantity distribution to the fire deck.
    The amount of coolant through the first cooling jacket of the cylinder block is thus varied depending on the load, in each case - minus the escaping via a possible degassing between the first and second cooling jacket coolant - total or full amount of coolant on the fire deck over or by the adjoining the fire deck part of the second cooling jacket is guided and is derived only after cooling the valve bridges.
    In order to achieve a flow field independent of the switching position in the second cooling jacket, it is advantageous if the flow connection between the first cooling jacket and the second cooling jacket is arranged in the region of at least one longitudinal side of the internal combustion engine.
    The bypass flow path is arranged between the switching device and the second cooling jacket in the cooling circuit. A valve chamber of the switching device can be connected to a main inlet of the cooling circuit.
    Preferably, a first distributor strip is arranged in the cooling circuit between the switching device and the first cooling space. Furthermore, a second distribution strip in the cooling circuit can be arranged between the switching device and the second cooling space. A flow field of the coolant in the second cooling space that is uniform for all switching positions can be achieved if the first cooling space is connected to the second cooling space via the second distribution strip, preferably the first cooling space per cylinder via at least one flow connection to the second distribution strip fluidly connected.
    The first and / or distribution ledge may be integrated with the cylinder block or also externally formed therewith. It is particularly advantageous, however, if the second distributor bar is integrated in the cylinder head. This allows a very compact design.
    Through the distribution strips, the coolant flow through the first cooling jacket can be activated or deactivated with a single switching device. In particular, it is possible to dispense with the second distributor strip if a switching device is arranged per cylinder, which can be connected to the second cooling jacket via one bypass flow path per cylinder.
    In a particularly preferred embodiment variant, it is provided that the second cooling jacket of the cylinder head has an upper and a lower partial cooling space, the lower partial cooling space being arranged between the upper partial cooling space and a fire deck of the cylinder head, and wherein the upper partial cooling space is directly connected to the first cooling jacket via a connecting duct the cylinder block is flow-connected, and wherein preferably the second distributor bar is part of the upper part of the cooling jacket. Upper and lower part of the refrigerator are separated by an intermediate deck. As a lower part of the refrigerator here is understood here directly adjacent to the fire deck partial cooling room. The upper part of the cooling chamber closes in the direction of the cylinder axis to the lower part of the cooling chamber, wherein between the part of cooling chambers is formed by a broken through the injector for the injector tween deck.
    The upper part of the cooling chamber of the second cooling jacket can act as a distributor / collector for the fire deck. The upper part cooling space communicates with the lower part cooling space via at least one flow connection, for example in the region of a central injection device. The coolant flows from the first cooling jacket of the cylinder block via the connection channel formed for example by a connecting pipe in the region of a longitudinal side of the internal combustion engine in the upper part of the cooling chamber and continues to flow in the transverse direction in the direction of the central injection device, where it passes through the transition in the intermediate deck in the lower part of the cooling chamber and - in transverse to the engine longitudinal plane or radially to the cylinder axis arranged flow channels - thermally critical areas of the fire deck cooling - flows outward and is directed to a coolant outlet in the region of a longitudinal side of the cylinder head. In the region of the crossing, the central injection device can also be cooled, with the passage being able to be designed as a throttle and serving to optimize the flow of the fire deck.
    The invention will be explained in more detail below with reference to FIG.

    FIGS. 1 to 6 each show an internal combustion engine 1 with a cylinder block 2 and a cylinder head 3, a first cooling jacket 4 being arranged in the cylinder block 2 and a second cooling jacket 5 being arranged in the cylinder head 3. In the area of the fire deck 6, the cylinder head 3 is connected to the cylinder block 2, wherein a cylinder head gasket 7 is arranged between the cylinder block 2 and the cylinder head 3. The cylinder axis is designated by reference numeral 24.
    The first cooling jacket 4 and the second cooling jacket 5 are part of a cooling circuit not shown in detail for a liquid cooling medium and fluidly connected to each other. In the cooling circuit, a by a switching device 8, for example, a Umschaltklappe - formed actuator is arranged, wherein in a valve chamber 9, a main inlet 10 of the cooling circuit opens. From the valve chamber 9, a coolant inlet 11 of the first cooling jacket 4, as well as a bypass flow path 12 bypassing the first cooling jacket 4, which leads, for example via a transfer channel 13, to the second cooling jacket 5 in the cylinder head 3. The flow connection between the main inlet 10 and the coolant inlet 11 on the one hand and the bypass flow path 12 on the other hand is controlled by the switching device 8.
    The switching device 8 has a first switching position A, a second switching position B and at least one intermediate position C. In the first switching position A of the main inlet 10 is connected only to the coolant inlet 11 of the first cooling jacket 4, the flow connection to
    Bypass flow path 12 is blocked. In the second switching position B, the main inlet 10 is only fluidly connected to the bypass flow path 12, while the coolant inlet 11 is separated from the main inlet 10. In the intermediate position C, the main inlet 10 is fluidly connected to both the coolant inlet 11, and with the bypass flow path 12, wherein the distribution of the flow to the coolant inlet 11 and the bypass flow path 12 can be adjusted by the exact position of the switching device 8.
    The flow of the coolant is indicated by fully drawn arrows S.
    Dashed arrows indicate deactivated flow paths.
    In the exemplary embodiments shown, the second cooling jacket 5 has an upper part cooling space 5a and a lower part cooling space 5b adjacent to the fire deck 6. Between the upper and lower part of the cooling chamber 5a, 5b, an intermediate deck 14 is arranged. Per cylinder Z, a central fuel supply device 20 is provided, which is arranged in an injector 21. In the area of the injector sleeve 21, the intermediate deck 14 has crossings 19 from the upper part cooling space 5a into the lower part cooling space 5b.
    In the exemplary embodiments, a first distributor strip 15 arranged in the longitudinal direction of the internal combustion engine 1 in the cylinder block 2 adjoins the first longitudinal side 1a of the internal combustion engine 1, which uniformly distributes the coolant for the first cooling jacket 4 longitudinally to the individual cylinders Z, as indicated schematically in Fig. 7. The bypass flow path 12 opens into a second distributor strip 16, which can be arranged either in the cylinder block 2 or in the cylinder head 3. Alternatively, it is also possible to form the distributor strips 15, 16 as separate components connected to the cylinder block 2 or the cylinder head 3. The second distributor strip 16 serves to distribute the coolant in the second cooling jacket 5 in the longitudinal direction in order to achieve uniform heat removal from thermally critical regions of the cylinder head 3. The second distributor strip 16 can also assume the function of a collecting bar for per cylinder Z from the first cooling jacket 4 flowing coolant. The second distribution strip 16 may also be part of the upper part cooling space 5a.
    The coolant is supplied in the region of at least one longitudinal side la, lb of the internal combustion engine 1 to the upper part cooling chamber 5a and flows according to the arrows S radially or transversely in the direction of the Injektorhülse 21. It passes through the crossings 19 in the lower part of the cooling chamber 5b and is here in Radial or transverse direction over thermally critical areas of the fire deck 6 out. After flowing through the second cooling jacket 5 substantially in the transverse direction of the internal combustion engine 1, the coolant leaves the cylinder head 3 through a main drain 17 in the region of a second longitudinal side lb of the internal combustion engine 1 and is possibly returned via a heat exchanger to a coolant pump, not shown, of the cooling circuit.
    Between the first cooling jacket 4 and the second cooling jacket 5, a, for example, arranged in the cylinder head gasket 7, degassing opening 25 may be provided.
    The amount of coolant through the first cooling jacket 4 of the cylinder block 2 is thus variable depending on the load, in each case the minus of about a possible vent 25 (see Fig. 1 to 3) between the first 4 and second cooling jacket 5 escaping coolant of a maximum of about 5% the entire flowing through the second cooling jacket 2 amount of coolant complete amount of coolant on the fire deck 6 over or passed through the adjacent to the fire deck 6 part of the second cooling jacket 5 and only after cooling the thermally critical areas of the fire deck 6 (for example, not shown Valve bridges) is derived.
    In each of the embodiments, main inlet 10 and main outlet 17 are arranged on different longitudinal sides 1 a, 1 b of the internal combustion engine 1. But it is also possible to position main inlet 10 and main outlet 17 on the same longitudinal side la, lb.
    FIGS. 1 to 3 show a first embodiment in which both the first and the second distributor strip 16 are arranged in the cylinder block 2 or in the region of the same first longitudinal side 1a of the cylinder block 2.
    Fig. 1 shows the switching device 8 in its first switching position A. The coolant flows according to the arrows S from the main inlet 10 in the valve chamber 9 of the switching device 8 and is guided by this via the coolant inlet 11 to the first manifold 15, of which the coolant in the first cooling jacket 4 surrounding the cylinders Z flows. After flowing around the cylinders Z, the coolant passes through the connecting channel 18 into the second distributor strip 16, where the coolant is collected and fed via at least one transfer channel 13 to the upper part cooling chamber 5a of the second cooling jacket 5 in the cylinder head 3. Thereafter, the coolant passes through the crossings 19 in the lower part of the cooling chamber 5b and leaves the second cooling jacket 5 through the main outlet 17. As can be seen by the arrows S in Fig. 1, the first and second cooling jacket 4, 5 in succession from the entire by the main inlet 10 supplied coolant flows through.
    Fig. 2 shows the switching device 8 in an intermediate position C, wherein the coolant in the valve chamber 9 of the switching device 8 is divided. A first part of the coolant now flows - as in the switching position A shown in FIG. 1 - via the first distributor strip 15, the first cooling jacket 4 and the second distributor strip 16 into the second cooling jacket 5. A second part passes directly through the bypass flow path 12. bypassing the first cooling jacket 4 - in the second distribution strip 16, where it flows together with the first part of the coolant and is passed together with this in the second cooling jacket 5. The flow through the upper and lower part of the cooling chamber 5a, 5b takes place as in the switching position A.
    Fig. 3 shows the switching device 8 in a second switching position B, wherein the coolant inlet 11 and the first distributor strip 15 separated from the main inlet 10, the bypass flow path 12 but is open. The coolant now flows-bypassing the first cooling jacket 4 -directly through the bypass flow path 12 into the second distributor strip 16 and is supplied uniformly to the upper partial cooling chamber 5a of the second cooling jacket 5 for all cylinders Z. The flow through the upper and lower part of the cooling chambers 5a, 5b takes place as in the switching position A. In order to dissipate in the stagnant coolant flow of the first cooling jacket 4 accumulated air due to incomplete filling of the water system, for example, in the cylinder head gasket 7 at least one vent 25 may be provided via which air can pass directly into the second cooling jacket 5.
    FIGS. 4 to 6 show a second embodiment variant in different switching positions of the switching device 8, in which the first distributor strip 15 is arranged in the cylinder block 2 in the region of the first longitudinal side 1a of the cylinder block 2.
    Fig. 4 shows the switching device 8 in its first switching position A. The coolant flows according to the arrows S from the main inlet 10 in the valve chamber 9 of the switching device 8 and is guided by this over the coolant inlet 11 to the first manifold 15, of which the coolant in the first cooling jacket 4 surrounding the cylinders Z flows. In the area of the second longitudinal side 1b of the internal combustion engine 1 arranged opposite one another with respect to the first longitudinal side 1a, a connecting channel 23 formed by a connecting tube 22 is arranged, which connects the first cooling jacket 4 to the upper partial cooling space 5a of the second cooling jacket 5 in the cylinder head 3. The connecting tube 22 is guided through the lower part of the cooling chamber 5b. Since the first cooling jacket 4 is always fluidly connected via the connecting channel 23 with the second cooling jacket 5, in this embodiment own vent can be omitted, since in the first cooling jacket 4 possibly accumulated air due to incomplete filling of the water system via the connecting channel 23 into the second cooling jacket 5 are derived can.
    After flowing through the first cooling jacket 4 in the transverse direction, the coolant is conducted through the connecting channel 23 into the upper partial cooling space 5a of the second cooling jacket 5, where the coolant is conducted in the radial direction or in the transverse direction to the central injector sleeve 21. Thereafter, the coolant passes through the crossings 19 in the lower part of the cooling chamber 5b and is directed radially or transversely outward over thermally critical areas of the fire deck 6 and leaves the second cooling jacket 5 through the main outlet 17. As indicated by the arrows S in Fig. 4th is evident, also in this
    Embodiment first and second cooling jackets 4, 5 successively flows through the entire through the main inlet 10 supplied coolant.
    Fig. 5 shows the switching device 8 in an intermediate position C, wherein the coolant in the valve chamber 9 of the switching device 8 is divided. A first part of the coolant now flows - as in the switching position A shown in FIG. 4 - via the first distributor strip 15, the first cooling jacket 4 and the connecting channel 23 into the upper partial cooling space 5a of the second cooling jacket 5. A second part passes directly through the Bypass flow path 12 - bypassing the first cooling jacket 4 - arranged in the cylinder head 3 second distributor bar 16, where it flows together with the first part of the coolant and is passed together with this by transfers 19 in the lower part of the cooling chamber 5b of the second cooling jacket 5. The flow through the upper and lower part of the cooling chamber 5a, 5b takes place as in the switching position A shown in Fig. 4.
    6 shows the switching device 8 in a second switching position B, wherein the coolant inlet 11 or the first distributor strip 15 is separated from the main inlet 10, but the bypass flow path 12 is open. The coolant now flows-bypassing the first cooling jacket 4 -directly through the bypass flow path 12 into the second distributor strip 16 and is supplied uniformly to the upper partial cooling chamber 5a of the second cooling jacket 5 for all cylinders Z. The flow through the upper and lower part of the cooling chambers 5a, 5b takes place as in the switching position A.
    In Fig. 7, the coolant flow to the second distribution strip 16 in the second switching position B of the switching device 8 is shown in a schematic side view of the first and second distribution strips 15 and 16, wherein the cylinder Z are symbolized by rectangles. The coolant flow flows from the main inlet 10 - as indicated by the arrows S - in the valve chamber 9 and is passed through the switching device 8 to the bypass flow path 12 and on to the second distribution bar 16. The first distribution bar 15 is separated in this switching position B from the main inlet 10. The second distribution strip 16 may be formed in the cylinder block 2 or in the cylinder head 3 as part of the upper part cooling space 5a.
    In both embodiments, the switching device 8 is formed by a switching flap. However, the switching device 8 can also be realized - with equivalent function - by two individual shut-off valves, wherein a respective shut-off valve can be arranged in the region of the coolant inlet 11 and in the region of the bypass flow path 12. As a result, a maximum volume flow through the cylinder head 3 can be made possible under all operating conditions and variations of the volume flow of the cylinder block 2 between 0% in warm-up and 100% in the full load case. This results in a particularly efficient cooling of the cylinder head 3. The cylinder head 3 thus acts as a collecting element of all partial volume flows.
    Particularly advantageous is the combination with the - shown in FIGS. 1 to 6 - two-part second cooling jacket 5 and so-called "top-down" cooling concepts in which the coolant flow from the upper part of the cooling chamber 5a in the lower part of the cooling chamber 5b occurs because in the large upper part of the cooling chamber 5 a different Zuströmpositionen be compensated at the constriction formed by the crossover 19 in the intermediate deck 14 and thus the switching positions of the switching device 8 have virtually no effect on the cooling effect of the fire deck 6. The upper part cooling chamber 5a of the second cooling jacket 5 acts as a distributor strip / collector for the fire deck 6. The executed as a throttle crossover 19 serve to optimize the flow of the fire deck. 6
    Regardless, the total volume flow through the main inlet 10 - for example, by a controllable water pump or by other control elements - be variable and oriented to the respective cooling requirement at thermally critical points of the cylinder head 3.
