ABSTRACT:
A cylinder head assembly for an internal combustion engine houses a camshaft position sensor for determining an angular position of a camshaft. A cylinder head upper is disposed between a cylinder head and a cylinder head cover, covering a part of a top opening of the cylinder head. The cylinder head is softly mounted, while the cylinder head upper is rigidly mounted on the cylinder head. The cylinder head upper includes a sensor boss for the camshaft position sensor, so that the camshaft position sensor is facing downward toward a signal plate attached to the camshaft.
