In an overhead cam design, what components are added to transfer motion if the camshaft is offset?

In an overhead cam design, when the camshaft is offset, rocker arms are employed to transfer the motion from the camshaft to the engine's valves. The rocker arms pivot at a fulcrum point and translate the rotational motion of the camshaft into linear motion that opens and closes the valves. This is essential for allowing the engine to breathe properly by controlling the timing of air and fuel intake, as well as exhaust gas expulsion.

In contrast, pushrods are typically found in overhead valve (OHV) designs instead of overhead cam configurations. Connecting rods are crucial in linking the pistons to the crankshaft, and cylinder heads serve as the housing for the combustion chambers and valve train components. While all these components are vital to an engine's operation, rocker arms are specifically the correct choice for facilitating the motion transfer in an overhead cam setup when there is an offset in the camshaft.
