Cylinder head of internal combustion engine |
摘要 |
<p>A cylinder head (10) has ribs (32) that strengthen connections between bolt boss portions (22, 23) that receive therein head bolts for fastening the cylinder head (10) to a cylinder block, and ribs (30, 31) that strengthen connections between the bolt boss portions (22) and a housing boss portion (20) provided over a central portion of each combustion chamber (14) for housing a fuel injector, via valve guide boss portions (21) in which engine valve guides are disposed. The ribs (30-32) effectively transmit the fastening forces of the head bolts to the boss portions (20, 21) located over each combustion chamber (14), thereby efficiently increasing the rigidity of the cylinder head (10) against the combustion pressure. <IMAGE></p> |
