    The invention relates to an internal combustion engine with a coolant jacket, which at least partially surrounds a cylinder arrangement arranged between a cylinder head sealing plane and a crank chamber with at least two cylinders arranged next to one another and is divided into a first jacket section remote from the crank chamber and a second jacket section near the crank chamber, the separation being separated by a Insert element
    is formed, which is inserted into the coolant jacket.
    Various solutions are known from the prior art in order to efficiently produce cylinder arrangements of internal combustion engines during operation
    cool.
    For example, DE 33 109 57 A1 discloses a cylinder block with a water jacket, with a partition dividing the water jacket into an upper bore section and a lower bore section. The dividing wall rises continuously (that is to say runs obliquely in relation to a cylinder head sealing plane) and has openings via which the upper bore section is coupled to the lower bore section. The production of such a shaped partition in the water jacket is complex and costly. The connection between the upper and lower bore section causes uncontrolled flow crossings and prevents optimal cooling of the internal combustion engine that is tailored to the spatial requirements.
    AT 15665 U1 discloses a cooling structure for an internal combustion engine with a coolant jacket around a cylinder arrangement, the coolant jacket being divided into an upper jacket section and a lower jacket section by a partition. The partition is formed by a flat insert element, which is inserted into the coolant jacket and rests on a circumferential shoulder between the lower and the upper jacket section. A similar separation between a lower and an upper jacket section of a coolant jacket is from the publication
    JP H 11294 254 A known.
    WO 2008/010584 A1, US 7,032,547 A and EP 3 239 507 A1 each show a separation between a lower and an upper jacket section,
    which is supported by spacers on the bottom of the coolant jacket.
    EP3239508 A1 discloses a spacer which is arranged between the walls of the coolant jacket via rubber elements.
    WO 08/016127 A1 shows a partition element for a coolant jacket with a flexible lip element for sealing on an inner wall of the
    Coolant jacket.
    Further separations of a coolant jacket between a lower and an upper jacket section are known from the publications JP 2000 345 838 A, JP 2005 315 118 A2, or EP 1 930 564 A1.
    Known separations have the disadvantage of a relatively high production outlay and / or an inadequate separation between the lower and upper casing sections, so that leakage flows between the separation and the wall of the cooling liquid casing, which adversely affect the cooling, cannot be ruled out.
    The object of the invention is therefore to provide an internal combustion engine with a coolant jacket that is easy to manufacture, and with the
    Leakage flows can be avoided.
    This object is achieved according to the invention with an internal combustion engine mentioned at the outset in that the insert element has a first leg and a second leg which is at an angle with respect to the first leg, the insert element preferably having an im
    Has a substantially V-shaped cross section.
    The measure according to the invention makes it possible to carry out the separation in the cooling liquid jacket only subsequently, that is to say after the cast part has been produced, by inserting the insert element. In particular, the legs inclined with respect to one another, when the insert element is in the inserted state, bring about a clamping action against mutually opposite walls of the coolant jacket. With a V-shaped cross section, a
    Clamping of the insert element enables so that no further precautions for assembly are necessary. V-shaped is understood in the context of the present invention to mean an essentially angular transition between the first and second leg, which can also have a rounding due to the production. Also a version with a U-shaped cross section in the broadest
    So sense is possible.
    An “upper” first jacket section is formed away from the crankcase or near the fire deck. A “lower” second jacket section, on the other hand, is arranged close to the crankcase or away from the fire deck. The first jacket section serves to cool the hot upper cylinder area, which is adjacent to the fire deck, and the second jacket section, for cooling the cooler lower cylinder area, which
    borders on the crankcase.
    In the present description, coolant jacket is to be understood as the volume in which the coolant (in particular water, possibly with suitable additives) is located or in which it circulates during operation. The coolant jacket is formed as a cavity, which surrounds the cylinder arrangement, in a cast part or block. The insert element is preferably made in one piece and - preferably with the exception of the coolant transfer - has a closed (ring or “multi-ring”) contour. The contour follows
    thereby advantageously the course of the cylinder walls.
    The coolant or water jacket formed, for example, in the cylinder block is thus divided into a lower and an upper region by the insert element. The coolant jacket can thus be formed in a one-piece cast core (cylinder block) as an “open deck” configuration. The insert element takes on the function of a partition or a panel. The separation allows two coolant spaces to be preferably formed with different temperature levels. With the insert element according to the invention, separate cooling strategies for the first and the second jacket section can thus be implemented very easily. Different temperature levels can be reached in the cylinder head and in the cylinder block. For example, while cooling takes place in the first jacket section and thus close to the cylinder head during the warm-up process, one can
    Flow through the second jacket section can still be suppressed to a
    achieve faster heating of the cylinder block and thus reduce the friction. Variants are also conceivable where the two jacket sections are loaded at all by different temperature circuits. In order to facilitate production, it is advantageous if the lower second jacket section and at least part of the upper first jacket section are formed in a preferably one-piece casting. This highlights the advantage of the insert particularly well. In a preferred embodiment it is provided that the lower jacket section and at least part of the upper jacket section are formed in a cylinder block.
    The cross section of the insert element is preferably convex with respect to the second jacket section or concave with respect to the first jacket section. This means that the two legs of the insert element open upwards. In other words, in this exemplary embodiment, the open side of the V-shaped cross section faces the fire deck or the cylinder head sealing plane, while the closed side or the tip of the “V” forming the cross section points in the direction of the crank chamber. An embodiment variant of the invention provides that the first leg and the second leg span an angle between approximately 60 ° and 120 ° - preferably approximately 90 °. This makes it possible to insert the insert element into the coolant jacket from the side of the open fire deck or from the side of the cylinder head sealing plane. Preferably, a reference plane of the insert element formed by the intersection of the first and second legs is configured normally for the axial extension of the cylinders of the cylinder arrangement. In other words, the reference plane defined by the insert element is oriented perpendicular to a longitudinal axis of the cylinder. As a result, the height of the respective jacket section along the entire circumference remains constant, which takes into account the temperature gradient running in the axial direction and uniform heat dissipation through the first jacket section flowing in particular in the crankcase space
    Coolant is achieved.
    The coolant jacket preferably has at least one coolant inlet and at least one coolant outlet, the first jacket section having the coolant inlet, preferably adjacent to or in the region of a cylinder head sealing plane of the internal combustion engine and / or the second jacket section having the coolant outlet. With that you can
    direct the coolant to the thermally higher stressed area near the cylinder head sealing level and then pass it on to the part near the crankcase that needs to be cooled less.
    In another embodiment variant of the invention it is provided that the first jacket section and the second jacket section are flow-connected to one another via a coolant transfer, which is preferably formed by the insert element. The first jacket section can have the coolant inlet, which is preferably arranged in the area of the cylinder head sealing plane - ie close to the fire deck or adjacent to the fire deck - of the internal combustion engine. The second jacket section advantageously has a coolant outlet which is arranged in the region of a narrow side of the cylinder arrangement. The coolant enters the first jacket section via the coolant inlet, flows through the coolant transfer in the insert element into the second jacket section and leaves the second jacket section through the coolant outlet.
    In order to avoid short-circuit flows and to ensure that the coolant flows around all cylinders as far as possible, it is advantageous if at least one coolant lock is provided along the circumference in the first jacket section and / or in the second jacket section, the coolant lock preferably separating two areas of a jacket section from one another separates. Two regions of the first jacket section are expediently
    separated from each other.
    Here, “scope” is to be understood as the scope of the coolant jacket, which extends at least partially around the cylinder arrangement. In other words, at least one coolant lock is provided along the course of the coolant jacket around the cylinder arrangement.
    This allows a defined cooling circuit to be created within a jacket section. For example, the coolant barrier (for example in the first or second jacket section) can be arranged between the inlet opening and the outlet opening for the coolant in order to cause a (one-time) flow around the cylinder arrangement before the coolant
    Leaves section of coat again.
    It is particularly expedient if at least one coolant lock is arranged in the area of the coolant transfer, preferably directly adjacent to the coolant transfer.
    A particularly good flow around all cylinders can be achieved if the coolant inlet opens into the first jacket section on a first side of the coolant lock facing away from the coolant transfer, the coolant inlet advantageously being arranged directly adjacent to the coolant lock on the first side of the coolant lock. The coolant transfer is advantageously on a second side of the coolant barrier facing away from the first side, preferably directly
    arranged adjacent to the coolant lock.
    In a simple embodiment variant of the invention it is provided that the coolant lock is formed by a partition element which is preferably essentially parallel to the cylinder axis and / or extends over the entire height of the first jacket section. In order to save parts and simplify manufacture and assembly, it is particularly advantageous if the partition element is formed in one piece with the insert element, the partition element preferably being an area of the insert element that is bent or bent by a bending process
    is trained.
    In order to achieve the best possible heat dissipation and uniform cooling in a cylinder arrangement which has at least one cylinder row with a plurality of cylinders arranged in series, a first outer cylinder and a second outer cylinder being arranged at different ends of the cylinder arrangement, it is advantageous if a Coolant entry into the coolant jacket in the area of the first outer cylinder and a coolant exit from the coolant jacket in the area of the second
    outer cylinder is arranged.
    In terms of packaging - that is, in relation to a compact and space-saving arrangement, it is advantageous with regard to the other components of the internal combustion engine if a coolant inlet into the coolant jacket is arranged in the region of a long side of the cylinder arrangement. Furthermore, it is convenient
    7728
    if a coolant emerges from the coolant jacket in the area of a
    Narrow side of the cylinder arrangement is arranged.
    The insert element is preferably made of a material with at least one of the following properties: non-metallic material; Material with an insulating effect, which thermally insulates the first jacket section from the second jacket section; elastic material, in particular spring steel or plastic or a composite material. The insert element can therefore also be made of a different material than the cast part forming the cylinder block. In order to enable easy insertion, it is advantageous, for example, if the insertion element consists of an elastic material, for example spring steel or sheet metal. A composite material, that is to say made of steel and rubber or plastic and rubber, can also advantageously be used, with for example the
    Composite materials can be arranged in layers.
    If a thermal separation between the lower and the upper section is desired, it is advantageous if the insert element is formed from, for example, a non-metallic material with low thermal conductivity (or low thermal conductivity coefficient) than the cylinder block, so that the insert element separates the upper and lower Jacket section not only seals against each other, but also thermally insulated from each other. For example, the insert element can be made of plastic or also of ceramic - for example of an elastic ceramic based on a titanium carbide compound.
    The insert element can rest or be constrained in the coolant jacket on or between corresponding structures. For example, the insert element could be fixed or constrained between the walls of the coolant jacket. Alternatively or additionally, the insert element can be attached to a
    Structure to be glued. The insert element can also be exchangeable.
    An embodiment variant of the invention provides that at least one support element is arranged in the second jacket section, on which the insert element rests, or which is firmly connected to the insert element. In particular, the support element can be formed in one piece with the insert element. The insert element is supported in the second jacket section, for example on the bottom of the second jacket section, via the support element.
    In one embodiment variant of the invention, it is provided that during manufacture in an open-deck configuration, a coolant jacket is cast in the cylinder block, which has a narrower diameter in an area facing away from the cylinder head than near the cylinder head, so that there is a transition between these diameters one paragraph results. The transition between the area facing away from the cylinder head and the area close to the cylinder head is preferably designed as a - preferably circumferential - shoulder. On this paragraph, the insert element (screen or partition) is inserted, which spatially divides the coolant jacket of the cylinder block into an upper first and a lower second jacket section. The insert element thus lies at least partially on the heel. The shoulder can be integrally formed in the cast part or cylinder block in which the coolant jacket is formed. No further structures or measures are required here for the support or positioning of the insert element.
    The cross section of the second jacket section is advantageously smaller than the cross section of the first jacket section. If the transition between the lower and upper jacket section is abrupt and not running, there is automatically a paragraph for the insertion of the insert element.
    In a variant of the invention it is provided that the insert element not only divides the first and the second jacket section spatially, but also completely hydraulically separates them from one another, the insert element sealingly abutting the walls of the coolant jacket of the cylinder block. In this embodiment, the first casing section is therefore completely sealed off from the lower casing section. The first jacket section and the second jacket section can each have a separate coolant inlet and / or coolant outlet. This enables areas of the cylinder block or cylinder head to be cooled independently of one another and to different degrees
    become.
    As a result, different cooling strategies can be carried out in the respective jacket sections, depending on the requirements or coordinated with the operating mode and / or phase, the flow-mechanical influencing being eliminated at all and the mutual thermal coupling
    is minimized. The first jacket section and the second jacket section can
    thus be fed separately with cooling water from a common
    Pump or can come from separate pumps.
    From the upper first jacket section, for example, the coolant can be sent further into the cylinder head on the inlet side, from there it can get back into the cylinder block on the outlet side and leave the coolant jacket via an outlet opening. The lower, second jacket section is charged separately: Here, the coolant either flows in on one side and out on the opposite side, or the inlet and outlet openings are arranged next to one another, but a liquid barrier is provided between them, so that the coolant flows once after being supplied flows around the cylinder assembly and then runs again. Other inlet and outlet solutions are also possible without restricting the inventive function.
    Basically, with the invention two divided temperature levels or a divided cooling circuit - in a one-piece cast cylinder block, but divided by the aperture-shaped insert element - can be achieved in a simple and inexpensive manner.
    In the variants described, it is advantageously provided that the coolant jacket is configured in an open configuration on the cylinder head side. This means that the cylinder block and the coolant jacket executed therein are designed to be open on the side facing a cylinder head sealing plane and are therefore closed by the cylinder head gasket or the cylinder head when used as intended. The upper first jacket section thus faces the cylinder head. Thanks to the open configuration, the insert can also be inserted without any problems. This can be done, for example, from above or from the side of the cylinder head before it is installed. The upper jacket section can be formed in a in the cylinder head
    Skip cooling volume.
    The invention is explained in more detail below on the basis of non-limiting exemplary embodiments which are illustrated in the figures. In this

    Fig. 7 shows the cylinder block in a section along the line VII - VII in Fig. 4 and
    8 shows the cylinder block in a section along the line VIII-VIII in FIG. 7,
    1 shows a cylinder block 1 of an internal combustion engine 2 with a cylinder arrangement 3 with a plurality of cylinders 4 arranged in series, the cylinder block 1 having a cooling structure 5 with a coolant jacket 6. The cylinder block 1 can be integrally formed with a crankcase 8 forming a crank chamber 7 or be formed separately from it. The coolant jacket 6 surrounds the cylinders 4 and is divided into an upper first jacket section 10 and a lower second jacket section 11 by a partition 9. The partition 9 is formed by an insert element 90, which in
    the coolant jacket 6 is inserted.
    In the exemplary embodiment shown, the coolant jacket 6 is configured in an open configuration (“open deck”) on the cylinder head side, ie toward a cylinder head sealing plane 12, and together with the cylinder block 1
    poured.
    The insert element 90 spatially separates the first jacket section 10 from the second jacket section 11, as shown in FIG. 2. The insert element 90 has a V-shaped cross section with a first leg 91 and a second leg 92 angled to it, the first leg 91 and the second leg 92 - in the installed state - an angle β between approximately 60 ° and 120 ° - preferably span about 90 °. The first leg 91 runs
    thus at an angle β relative to the second leg 92. In particular
    in the disassembled state, the extension of the insert element 90 in a radial direction with respect to the cylinder arrangement 3 is greater than in the installed state, so that there is a clamping effect against opposing walls of the coolant jacket 6. The insert element 90 can thus be mounted in the coolant jacket 6 simply and without special tools.
    Insert element 90 is inserted into coolant jacket 6, which is open at the top - that is, toward cylinder head sealing plane 12 - in such a way that the convex side - in particular an outer edge formed by the intersection of the two legs - faces the crank chamber. The outer edge 93 of the insert element 90 is formed by the intersection of the two legs 91, 92. A reference plane £ of the insert element 90, which extends through the outer edge 93, is essentially normal to the cylinder axis 4a
    positioned.
    Favorably, the distance a (see FIG. 3) between the end edges 91a, 92a of the two legs 91, 92 of the insert element 90 in the disassembled state, that is to say not yet inserted into the coolant jacket 6, is somewhat larger than the greatest width b of the coolant jacket 6 (see 2), measured between two mutually facing walls 6a, 6b of the coolant jacket 6. In the exemplary embodiment shown, the coolant jacket 6 is designed with approximately the same width b over its entire circumference and over its entire height. When inserting the insert element 90 into the coolant jacket 6, the end edges 91a, 92a of the first leg 91 and the second leg 92 are pressed elastically against the walls 6a, 6b of the coolant jacket 6, whereby on the one hand the insert element 90 is elastically clamped between the walls 6a, 6b and is fixed. On the other hand, the end edges 91a, 92a elastically pressed against walls 6a, 6b separate and seal the first jacket section 10 from the second jacket section 11. The insert element 90 is preferably made of an elastic material, for example a non-metallic material or a material with low thermal conductivity, preferably plastic or ceramic.
    As is clearly shown in FIG. 3, the insert element 90 is not designed to be closed in the circumferential direction, but instead has a coolant transfer 94.
    which - in the installed state - the first jacket section 10 of the
    Coolant jacket 6 is fluidly connected to the second jacket section 11. The coolant transfer 94 is formed by a recess in the insert element 90 or - as can be seen in FIG. 3 - by a bent section 95 of the insert element 90. The bent section 95 thus forms a dividing wall element 97, which protrudes normal to the reference plane & upwards - that is, parallel to the cylinder axis 4a in the direction of the cylinder head sealing plane 12 and functions as a coolant lock 96, which separates two regions of the first jacket section 10 from one another. The partition element 97 preferably extends over the entire height 10a of the
    first jacket section 10.
    In the exemplary embodiment, the cooling structure 5 has a coolant inlet 13 and a coolant outlet 14, which are molded into the cylinder block 1. The coolant inlet 13 opens into the first jacket section 10 in the region of the cylinder head plane 12 and is arranged, for example, on a longitudinal side 1 a of the cylinder block 1 in the region of a first outer cylinder 41. This enables a quite compact configuration. The coolant outlet 14 starts from the second jacket section 11 and is arranged in the region of a second outer cylinder 42, for example on a narrow side 1b of the cylinder block 1. By coordinating the arrangements of the coolant inlet 13 and the coolant outlet 14, the flow around the cylinders 4 is as complete as possible and thus optimal heat dissipation
    ensured.
    As can be seen from FIG. 4, the coolant inlet 13 opens into the first jacket section 10 on a first side 15 of the coolant lock 96 facing away from the coolant transfer 94, the coolant inlet 13 being arranged directly adjacent to the coolant lock 96 on the first side 15 of the coolant lock 96 . The coolant transfer 94 is on a second side 16 of the coolant barrier facing away from the first side 15
    96 arranged directly adjacent to this.
    In an embodiment variant shown by dashed lines in FIG. 7, it can be provided that a circumferential shoulder 99 is formed in the transition area between the first jacket section 10 and the second jacket section 11,
    on which the insert element 90 rests or rests. Paragraph 99 can do so
    result from the fact that the cross section of the second jacket section 11 is smaller
    is than the cross section of the first jacket section 10.
    In a further embodiment variant, represented by dashed elements in FIG. 3, it is provided that at least one or more support elements are arranged in the second jacket section 11, on which the insert element 90 rests, or which is firmly connected to the insert element 90. By means of the support element 98, the insert element 90 can be positioned in the coolant jacket 6 in the correct position during assembly, since the support elements 98 are supported on the bottom of the coolant jacket 6 on the crankcase side.
    The coolant flows according to the arrows S through the coolant inlet 13 into the upper first jacket section 10. A short-circuit flow to the coolant transfer 94 is prevented by the coolant lock 96. The coolant therefore flows according to the arrows S while flowing around all the cylinders 4 of the cylinder arrangement 3 in the circumferential direction along the first jacket section 10 to the coolant transfer 94 and further into the lower second jacket section 11 of the coolant jacket 6 (see FIG. 6). Here, the coolant flow is divided, as indicated in FIG. 8 by the arrows S, a part flowing around the cylinder 4 of the cylinder arrangement 3 and the other along the long way in the second jacket section 11
    leaves second jacket section 11 through the coolant outlet 14.
    The coolant enters the first jacket section 10 near the cylinder head sealing plane 12 or near the hot zones of the cylinders 4, and exits in the lower second jacket section 11. This has the advantage that the coolant is at a relatively low temperature in the particularly hot ones Areas of the cylinder assembly 3 can still absorb a lot of heat and only then
    flows through cooler or less critical areas.
    The arrangements of the coolant inlet 13, the coolant outlet 14 and the coolant outlet 94 are coordinated such that the inflow, transfer and exit of the coolant take place after the flow around the cylinders 4 is as complete as possible; ideally, the coolant inlet 13 and the coolant outlet 14 are arranged opposite to each other by a maximum
    To achieve flow.
    A defined flow direction is predetermined by the coolant lock 96 through the partition element 97 integrated in the insert element 90. The arrangement of the partition element 97 directly next to the coolant inlet 13 prevents quiet zones from forming in which the coolant stagnates. Because the coolant transfer 94 is provided in the second jacket section 11 directly next to the partition element 10, the coolant is forced to flow around the cylinders 4 completely, so that the best possible heat dissipation without pressure loss or without formation of stagnation zones is made possible. The transition into the second jacket section 11 thus takes place approximately in the area of the coolant inlet 13 and thus practically opposite the coolant outlet 14, so that a practically complete flow around the cylinders 4 is also effected in the second jacket section 11. The provision of the partition wall element 97, which is normal to the reference plane eg, enables the coolant lock 96 to be manufactured particularly easily, since the insert element 90 is simple
    cut open at one point and bent over.
