Question

Quizplus · Accepted Answer

The camshaft rotates at half the speed of the crankshaft. This is because the camshaft is driven by the crankshaft through a timing belt or chain with a different diameter, which results in the slower rotation speed. This slower speed allows the camshaft to open and close the engine's valves at the right times for combustion.
