- AT 515 143 B1 and AT 503 182 A2 each disclose a liquid-cooled internal combustion engine with a cylinder head and a cylinder block, with the cylinder head having two partial cooling chambers arranged one above the other, through which flow occurs according to a so-called top-down cooling concept.
- the two partial cooling chambers are separated from one another by an intermediate deck and flow-connected to one another in the area of a centrally arranged injector sleeve via at least one transfer channel.
- the coolant is fed via an inlet channel in the cylinder block, flows through a cooling chamber in the cylinder block surrounding the cylinder and is fed directly to the upper part of the cooling chamber of the cylinder head via flow transfers in the fire deck and supply channels.
- the cylinder head flows from top to bottom, so to speak, with the coolant first being fed to the upper part of the cooling chamber and, after flowing through the upper part of the cooling chamber, via the at least one transfer channel into the lower part of the cooling chamber, where the coolant flows radially from there via radial cooling channels in the area of the valve bridges is led inside to outside and finally leaves the cylinder head again via the laterally arranged discharge channel.
- AT 005 039 Ul describes a cylinder block for a liquid-cooled internal combustion engine with a distribution duct and a collecting duct for a coolant, the distribution duct being arranged above the collecting duct in the area of a side wall of the cylinder block and the distribution duct being flow-connected to a first cooling chamber via a supply duct.

- the first cooling chamber is flow-connected to a second cooling chamber around the cylinder liner, which is adjacent in the direction of the crank chamber and is connected to the distribution channel via at least one transfer opening.
- AT 501 008 A2 discloses a liquid-cooled internal combustion engine with a cooling jacket around the cylinders in the crankcase, with individual cylinder heads with at least two cooling chambers arranged one above the other in the cylinder head, the cooling jacket of the crankcase and the lower cooling chamber in the cylinder head having four transfer openings distributed evenly around the circumference of the cylinder per Cylinder are connected to each other.
