Abstract

A cylinder head (10) has two water jacket portions (14, 15) that are vertically divided by a middle deck (13). A clamp (22) extends over an upper portion of a fuel injector (22). The clamp (22) is fastened to the cylinder head (10) by a fastening bolt (23), so that the fuel injector (20) is fastened and secured to an upper portion of the cylinder head (10) while being urged downward. A fastening bolt boss portion (19) into which the fastening bolt (23) is screwed extends through the upper water jacket (15) and interconnects the middle deck (13) and a top deck (12), which form a lower partition and an upper partition of the upper water jacket (15), respectively.
