In the overhead valve arrangement, where is the camshaft installed?

In the crankcase
In the cylinder block
In the cylinder head
Near the piston

The correct answer is: In the crankcase

In the overhead valve arrangement, the camshaft is typically installed in the crankcase. This location allows the camshaft to operate the valves through lifters, pushrods, and rocker arms that extend into the cylinder head. Placing the camshaft in the crankcase facilitates a simpler and more direct path for the valve actuation components to interact with the valves in the cylinder head, leading to efficient and reliable engine function. Options B, C, and D are incorrect because the camshaft is not typically installed in the cylinder block, cylinder head, or near the piston in an overhead valve arrangement. These components are crucial in an engine but do not house the camshaft in this specific configuration.
