    The invention relates to an internal combustion engine having a cylinder head designed jointly for a plurality of cylinders and a bushing unit for a plurality of cylinders fastened to the cylinder head.
    FR 551 128 discloses an internal combustion engine with a bushing unit attached to the cylinder head, wherein a cooling jacket is formed between the bushing unit and a surrounding housing.
    DE 198 49 912 describes a liquid-cooled internal combustion engine with a crankcase in so-called open-deck design, in which a plate is arranged between this and the cylinder head, which is connected to the cylinder liners or integrally formed, and with the interposition of the cylinder head gasket with the Cylinder head is bolted to a unit. This unit is connected to the crankcase by the cylinder head bolts. The plate has a cooling fluid space which communicates on the one hand through openings in the bottom of the plate with a coolant space surrounding the bushings in the crankcase and on the other hand through openings in the cylinder head gasket with a liquid space in the cylinder head.
    Furthermore, from EP 1 706 624 an internal combustion engine with a cylinder head and a split cylinder block is known, wherein the split cylinder block has an inner Biockteil with a liner unit and an outer housing forming outer block part.
    Known internal combustion engines with a bushing unit have the disadvantage that the seal relative to the cylinder housing and the assembly effort is relatively expensive.
    The object of the invention is to avoid these disadvantages and to simplify the assembly work, leaks should be reliably prevented.
    According to the invention this is achieved in that in the bushing unit, a cooling jacket assembly is formed with at least one cooling jacket, which preferably surrounds the cylinder. 2 (Pnnted: 2 ^ 09-2012 £ 014
    Because the cooling jacket is formed in the bushing unit, the cooling jacket no longer has to be sealed off from the cylinder housing. This facilitates the manufacturing and assembly costs.
    A first cooling jacket arranged in a region of the liner unit facing the cylinder head can be flow-connected to a cooling water flow path, preferably with at least one cooling water inflow and / or outflow channel in the cylinder head.
    In order to enable simple production, it is advantageous if the first cooling jacket is open towards the cylinder head, preferably in open-deck construction. This allows a simple production of the first cooling jacket of the liner unit. The supply of cooling jacket with cooling water is thus only through the cylinder head. Separate inflow or outflow openings in the cylinder block are therefore not required.
    In order to allow a particularly good temperature control of the cylinder, it is advantageous if in a side facing away from the cylinder head of the liner unit, a second cooling jacket is arranged, which is preferably separated from the first cooling jacket and connected to a Motorölströmungsweg. The first and the second cooling jacket are - seen in relation to the Zyiinderachsen - arranged in different axial sections of the liner unit.
    The first and second cooling jackets comprise each cylinder and are designed to be continuous for all cylinders.
    The areas of the cylinder liners, which occupy the pistons in the cylinders in the region of the top dead centers, while the first cooling jacket, the lower dead centers of the piston associated areas of the cylinder liners cooled by the second cooling jacket. This allows a different temperature of the upper and lower portions of the cylinder.
    The bushing unit can be releasably connected to the cylinder head in the region of a fastening region adjoining the cylinder head by at least one screw connection, preferably via lugs formed on the outside in a circumferential region of the bushing unit, wherein preferably the third
    Bushing unit is secured by screws, preferably from the side of the crankcase to the cylinder head. The power flow of the cylinder head bolts thus no longer passes through the cylinder liners to the crankshaft. This has the advantage that deformations of the liners can be reduced.
    It is particularly advantageous if the liner unit is completely free from a surrounding cylinder housing. As a result, stresses between liners and cylinder housing are prevented, and reduced deformation of the liners.
    Alternatively or in addition to screws can also be provided that the liner unit is attached by means of an adhesive bond to the cylinder head.
    In a further embodiment of the invention can be provided that the liner unit is sealed by means of a liquid seal to the cylinder head.
    The invention will be explained in more detail below with reference to FIGS.
    2 shows the cylinder head together with the bushing unit in an oblique view from above, FIG. 3 shows an internal combustion engine according to the invention in a side view, FIG. 4 shows the internal combustion engine in a top view, FIG. 5 shows the cylinder engine in a top view 6 shows the internal combustion engine in a section along the line VI - VI in FIG. 3, FIG. 7 shows a bushing unit in an oblique view from below, FIG. 8 shows the bushing unit 9 shows the liner unit in a plan view, FIG. 10 shows the liner unit in a side view, FIG. 11 shows the liner unit in a section according to the line XI - XI in FIG. 9 and FIG. 12 shows the liner unit in one Section along the line XII - XII in Fig. 10.
    The figures show an internal combustion engine 1 with a cylinder head 2, wherein on the cylinder head 2, a bushing unit 3 is fixed for a plurality of cylinders Z. The bushing unit 3 for a plurality of cylinders Z is integrally formed and, in the exemplary embodiment, has lugs 5 integrally formed on the outer circumference in a fastening region 4 adjoining the fire deck 2 a of the cylinder head 2 for releasing oil
    Recording of mounting screws 6. With the fastening screws 6, the bushing unit 3 is fastened to the cylinder head 2 from the side of the crankcase. About this screw a simple and rapid assembly and disassembly of the liner unit 3 on the cylinder head 2 is possible. Alternatively or in addition to the screw connection, the bushing unit 3 can also be connected to the cylinder head 2 by means of an adhesive bond.
    The fastening region 4 is located in a region adjoining the cylinder head. The running bushing unit is thus fastened to the cylinder head 2 via this attachment region 4. The bushing unit 3 is surrounded in the installed state by a not further shown and connected to the cylinder head 2 cylinder housing and released against this. This has the advantage that deformations of the liners can be reduced because attachment and support forces do not extend through the entire axial extent of the liners. The liner unit 3 is thus " hanging " only attached to the cylinder head.
    The bushing unit 3 has a cooling jacket arrangement with a first cooling jacket 6 adjoining the cylinder head 2 and a second cooling jacket 7, wherein the second cooling jacket 7 is arranged in a lower region of the liner unit 3 facing away from the cylinder head 2.
    The first and the second cooling jacket 6, 7 surround all the cylinders Z. The first cooling jacket 6 is designed to be open towards the cylinder head 2 and is in fluid communication with a coolant inflow channel 8 and / or a coolant outflow channel. Characterized in that the first cooling jacket 6 is formed open at the top, the production of the liner unit 3 is facilitated. The second cooling jacket 7 is in communication with motor oil-carrying flow paths.
    The bushing unit 3 may be provided in the region of the cylinder Z with a separate running surface 3a, which running surface 3a may be formed by a coating or a cast-eyelet.
