ABSTRACT:
An internal combustion engine cylinder head includes a lower water jacket chamber with a plurality of angularly spaced exhaust passages extending therethrough. Partition webs connect each of the passage walls with the jacket periphery to separate the jacket chamber into alternate inlet and outlet sections through which coolant flows around each exhaust passage from the inlet to the outlet section. The webs are made tangent to the passage walls on their sides toward their respective outlet sections to avoid forming stagnant pockets for coolant in the outlet section between the passage defining walls and the boundary wall. The webs may also extend tangent to internal stud bosses on their sides toward the inlet sections to also minimize pockets therein.
