Abstract
The invention relates to a liquid-cooled internal combustion engine comprising at least one cylinder block which has a cooling jacket () and comprises multiple cylinders (). The cooling jacket () has a base () facing a crankcase and a cover () facing a cylinder head sealing plane (), and the base () has an undulating course when seen in a lateral view of the cylinder block. A first spacing (H) between two adjacent cylinders () in the region of at least one first motor transverse plane () is larger than a second spacing (H) between the base () of the cooling jacket () and the cover () in the region of at least one second motor transverse plane () containing the cylinder axis () when measured in the direction of the cylinder axis () in both cases. In order to minimize cylinder deformations, the base () of the cooling jacket () has at least one first flat section () arranged on a first reference plane (ε) in the region of the first motor transverse plane (), wherein the first reference plane (ε) is preferably formed parallel to the cylinder head sealing plane () of the cylinder block. Thus, the base () has a roof-like shape starting from the flat section in the region between the screws in the free cylinder lining region (the cylinder tube between the tapped holes).
