ABSTRACT:
In a liquid cooled multi-cylinder internal combustion engine comprising an engine block having a cooling water space, wherein a cylinder head is mounted on the engine block by cylinder head bolts with a cylinder head gasket disposed therebetween, and the cylinder head includes a water space which is in communication with the engine block water space by passages extending through the gasket and the cylinder head bottom wall, the cylinder head bolts extend through the passages into the engine block in spaced relationship from the walls defining the passages such that cooling water flowing from the engine block cooling water space through the passages to the cylinder head cooling water space, flows along the cylinder head bolts maintaining them at cooling water temperature, and the cylinder head includes in its cooling water space longitudinal ribs extending between the cylinder head bottom and top walls for reinforcing the cylinder head.
