Abstract
The invention relates to a cylinder head (1) for a liquid-cooled internal combustion engine with several cylinders, comprising at least one intake port (5) and at least two exhaust ports (4) per cylinder (1), at least one first cooling chamber (2) adjacent to a fire deck and at least one second cooling chamber (3) adjacent to the first cooling chamber (2), with the second cooling chamber (3) extending over several cylinders. In order to improve cooling in the areas subjected to great thermal stress it is provided that at least one first cooling chamber (2) is provided per cylinder and the first cooling chambers (2) of two adjacent cylinders are separated from one another, with each first cooling chamber (2) comprising at least one first opening (7) and at least one transfer opening (8) to the second cooling chamber (3), and the first cooling chamber (2) is flowed through between the first opening (7) and the transfer opening (8) substantially in the longitudinal direction of the cylinder head (1).
