A camshaft in a car is a vital component of the engine's valve system. Its primary function is to control the opening and closing of the engine's intake and exhaust valves at specific intervals. The camshaft is typically driven by the engine's crankshaft through a timing belt or chain.

The camshaft consists of a series of lobes or cams that are strategically placed along its length. As the camshaft rotates, these lobes come into contact with the engine's valve lifters or cam followers, causing them to move. This movement then opens and closes the valves, allowing fuel and air to enter the combustion chamber and exhaust gases to exit.
