The main purpose of a fuel injector in a diesel engine is to deliver fuel at high pressure. Fuel injectors are crucial components of the diesel fuel system, responsible for atomizing the fuel into a fine mist and injecting it directly into the combustion chamber. This high-pressure delivery enables efficient mixing of the fuel with the incoming air, facilitating optimal combustion.

In a diesel engine, fuel must be injected at precisely the right moment during the engine cycle and at the correct pressure to ensure complete combustion, which enhances engine efficiency, power output, and reduces emissions. The high pressure helps to ensure the fuel is dispersed adequately into the combustion chamber, allowing for a more uniform and complete combustion process.

Understanding this function is essential for recognizing how diesel engines operate and the importance of maintaining the fuel injection system to ensure proper engine performance.
