摘要： An internal combustion engine cylinder head unit includes a number of gas flow ports extending upwardly from a fire deck. A common coolant passage extends between adjacent ones of the gas flow ports. A first coolant flow director includes a flow splitter extending downwardly into the common coolant passage so as to cause a coolant flow within the common coolant passage to remain attached upon an upper surface of the fire deck between adjacent ports. A second coolant passage runs about a radially outboard portion of the cylinder head unit, and flow in this passage is directed by a truncated bulk flow displacer extending from a rear wall of the second coolant flow passage. The second flow director causes the impingement of coolant upon both an upper surface of the fire deck and upon an outboard portion of at least one of the cylinder ports.
