Lesson 1/Learning Event 1
The F-head engine has its camshaft in the cylinder block. For the valves located in the block, it uses a
mechanism like the L-head engine. Rocker arms and pushrods are used on the valves in the head as with the
overhead valve engine.
On V-type and horizontal-opposed engines, one camshaft is generally located in the center of the engine and
operates the valves on both rows of cylinders. Of course, if the overhead cam method is used, a camshaft is
needed on each row of cylinders.
