A cylinder head for an engine

摘要

An internal combustion engine cylinder head unit for an engine is disclosed having a number of gas flow ports 30, 34 extending upwardly from a fire deck 20 and a common coolant passage 38 extending between adjacent ones of the gas flow ports 30, 34. A coolant flow director includes a flow splitter 42 extending downwardly into the common coolant passage 38 so as to cause a coolant flow within the common coolant passage 38 to remain attached upon an upper surface 24 of the fire deck 20 between adjacent ports 30, 34 so as to improve localised cooling.
