What is the function of the camshaft in a diesel engine?

The camshaft in a diesel engine controls the opening and closing of the engine's valves. It ensures that the intake valves open to allow air into the cylinders and the exhaust valves open to let out gases at the right times during the engine's cycle. This timing is crucial for efficient engine operation. The camshaft does not limit engine speed or control temperature; those functions are managed by other components. Understanding this helps with recognizing how engine parts work together for proper combustion and performance.
