摘要:
A number of embodiments of multiple valve internal combustion engines embodying a single camshaft for operating all of the multiple valves. The cylinder head is configured in such a way that it is reinforced across the center of the cylinder head by a bridging member and this bridging member can form a bearing surface for a center lobe of the camshaft. The camshaft is offset toward one side of the cylinder head and operates the valves through a plurality of rocker arms. In some embodiment, the rocker arms are journaled on a cam cover upon rocker arm shafts formed with reliefs aligned with openings in the cam cover for passing components such as a spark plug or a fastener for securing the cam cover to the cylinder head. Both single and multiple cylinder embodiments are disclosed.
