The camshaft in an internal combustion engine controls the opening and closing of the intake and exhaust valves. These valves allow air (and fuel) into the engine for combustion and then expel the exhaust gases after combustion. Here's a step-by-step breakdown:

1. The camshaft is connected to the crankshaft directly via a belt or chain. As the crankshaft, which is powered by the engine's pistons, turns, it also turns the camshaft.

2. The camshaft is designed with several lobes (also known as cams) along its length. Each lobe corresponds to a specific valve in the engine.

3. As the camshaft rotates, the lobes push against the valves, opening them. The shape and position of the lobes determine when and how far the valve opens.

4. Once the lobe has passed, the valve closes again, either through spring pressure or hydraulic pressure.

5. This process repeats, with the camshaft controlling the timing and duration of each valve opening and closing. This is critical for the engine's performance, as it affects the engine's ability to intake air and fuel and expel exhaust gases.
