FIELD: engines.
SUBSTANCE: invention can be used in internal combustion engines with liquid cooling. Cylinder head (1) with liquid cooling has on each cylinder one inlet channel (2) which enters into a combustion chamber, one outlet channel (3) adjacent to inlet channel (2), and, adjacent to outlet channel (3), fuel injection device (7) and cooling chamber (20). In fire deck zone there is, extending parallel to fire deck, cooling distribution channel (11), which enters annular space (8), surrounding fuel injection device (7). Annular space (8) has at least one radial first cooling groove (13) directed to zone (14) of valve seat arranged between inlet channel (2) and outlet channel (3) and adjoining fire deck. From annular space (8) and/or cooling distribution channel (11), at least another cooling groove (15) branches laterally, tangentially to outlet channel (3).
EFFECT: technical result is improved cooling of thermally critical zones of cylinder head.
