What is the purpose of a cylinder head in a diesel engine?

The cylinder head in a diesel engine serves several critical functions. It houses the combustion chambers, allowing for the compression of air and injection of fuel, which is essential for the combustion process. Additionally, the cylinder head contains components such as valves, fuel injectors, and often the intake and exhaust passages, facilitating the flow of air and exhaust gases. Overall, it plays a vital role in engine performance, efficiency, and emissions control.
