Abstract
An improved water jacket structure for a cylinder head that assists in transferring heat from a lower wall of the cylinder head to coolant flowing through passageway in the head. The passageway is defined in the cylinder head by the lower wall and an upper wall. The lower wall provides a plurality of cylinder top walls that overlie corresponding ones of the cylinders in the engine block. The upper wall includes a series of ribs that extend from the upper wall toward the lower wall. The ribs include an inlet rib, and a set of interconnected ribs. The interconnected ribs are disposed between adjacent cylinder topwalls. The set of interconnected ribs have first ends that are connected to one another, second ends that are spaced from one another, and a lower edge that is spaced a predetermined distance from the lower wall.
