    The invention relates to an internal combustion engine having at least one arranged in a cylinder block cylinder with a reciprocating piston, wherein a cylinder head is detachably connected to the cylinder block, with at least one exhaust gas turbocharger.
    The casings of exhaust gas turbochargers are usually formed separately from the cylinder block and cylinder head. However, this has a disadvantageous effect on the number of parts, weight and production costs.
    From the publications JP 62-162728 A2, DE 31 33 953 Al and JP 57-052624 A2 it is known to integrate exhaust gas turbochargers in cylinder heads. However, this requires a more or less massive intervention in the design of the cylinder head, which can occur in many cases space problems.
    Furthermore, from DE 31 33 952 Al and the SE 446 114 B integrated into the cylinder head volute casing known. The bearing housing is thereby inserted with the rotor of the exhaust gas turbocharger in a cylindrical bore with clearance. For the compressor, the spiral housing is also cast with play. According to this construction, it is only possible to exchange gaseous media between the cylinder head and the exhaust gas turbocharger rotor. The bearings are air-lubricated.
    The object of the invention is to minimize the machining and manufacturing costs in an internal combustion engine of the type mentioned and to achieve the most compact installation volume possible. In particular, the space for the cylinder head should be kept as small as possible.
    According to the invention this is achieved in that at least one spiral of the exhaust gas turbocharger is integrated into the cylinder block.
    The turbine housing of the exhaust gas turbocharger can be integrated in the cylinder block.
    It is preferably provided that the spiral of the exhaust gas turbine of the exhaust gas turbocharger is at least partially surrounded by a cooling jacket, wherein preferably the cooling jacket is integrated into the cylinder block.

    It is particularly advantageous if the cooling jacket communicates with at least one inlet and one outlet channel, wherein the inflow and outflow channels can be integrated into the cylinder block and / or into the cylinder head. As a result, external lines for the coolant supply of the exhaust gas turbocharger can be omitted.
    In order to keep the number of parts as small as possible, save space and to minimize the production cost, it is particularly advantageous if the shaft of the exhaust gas turbocharger is mounted on plain bearings, which are connected via at least one Schmiermittelzuführkanal with a lubricant circuit, wherein the lubricant supply hole in the cylinder block or the cylinder head is integrated. Furthermore, at least one lubricant return passage of the exhaust gas turbocharger can be integrated into the cylinder block or the cylinder head.
    In a further embodiment of the invention can be provided that at least one barrier air duct of the exhaust gas turbocharger is integrated into the cylinder block or the cylinder head.
    The exhaust gas turbocharger thus has no external lines. All connections, lines and channels can thus be integrated into the cylinder head or cylinder block.
    It is particularly advantageous if at least one inlet collector and / or at least one outlet collector is integrated in the cylinder head and / or in the cylinder block. Furthermore, at least one inlet line leading to the inlet header can be integrated in the cylinder head or in the cylinder block. The cylinder head can be closed by a cylinder head cover, in which at least one supply line to the inlet line can be integrated.
    The intake pipes may also be partially integrated into the cylinder head and / or cylinder block and partially housed in the cylinder head cover. The outlet ducts are preferably integrated in the cylinder head and / or in the cylinder block.
    The cylinder liners can either be integrally machined into the cylinder block or screwed into it. ncar / v »3 Printed: 27-03-2012 E014 10 2012/50101
    As an alternative to lubricating oil lubricated bearings, air-lubricated bearings can also be used.
    In contrast to the prior art known from DE 31 33 952 A1 and SE 446 114B, the bearing housing of the exhaust gas turbocharger is flanged together with the compressor housing of the compressor to the cylinder block, with an appropriate seal for the sealing of the pressure oil, the coolant passages and the drain line of oil and sealing air.

The not more dargestelite exit from the compressor coil 12 is connected via a connecting hose 15 and a charge air line 16 in the valve cap 17 with the cast intake manifold 7. At least the spiral 8 of the exhaust gas turbine 10 of the exhaust gas turbocharger ATL is at least partially surrounded by a cooling jacket 18, which is flow-connected via at least one inflow channel 19 and at the highest point via at least one outflow channel 20 with a cooling jacket 21 of the cylinder block 4 and the cylinder head 3. In the region of the cylinder block 4, an oil gallery 22 is arranged, from which a supply bore 23 leads to a lubricant supply channel 24 to the bearings of the shaft 28 of the exhaust gas turbocharger ATL. Reference numeral 25 denotes a transfer opening in the flange of the exhaust gas turbocharger ATL for the oil return and the blocking air discharge. The lubricant return passage 26 of the exhaust gas turbocharger ATL leads over the vertical part 27 of the return line back into the oil pan 32nd
    The exhaust gas turbine 10 may be welded onto the shaft 28. The oil supply line 24 leads via the pressure oil bore 24a to the bearing bushes of the sliding bearings 29 of the exhaust gas turbocharger ATL. The air inlet into the compressor is designated by reference numeral 30. The seal between the compressor housing 11 and the cylinder block 4 via a seal 31. The compressor housing 11 is fastened by screws 37 on the cylinder block 4.
    The exhaust gas leaves the exhaust gas turbocharger ATL via the exhaust gas outlet 36. Λ-7 ΛΛ ηΛίΙΟ
