What is the purpose of the inlet valve in a diesel engine?

The inlet valve in a diesel engine controls the flow of air into the combustion chamber during the intake stroke. Its primary purpose is to allow the engine to draw in the necessary air for the combustion process, which is essential for efficient fuel combustion and engine performance. Proper timing and operation of the inlet valve are crucial for optimizing power output and fuel efficiency. Additionally, it helps in ensuring that the engine runs smoothly by maintaining the correct air-fuel mixture ratiOS.
