1. Fuel tank: stores diesel fuel, usually located at or near the bottom of the generator set to ensure gravity fuel supply.
2. Fuel pump: responsible for delivering fuel from the fuel tank to the engine, which can be mechanically or electrically driven.
3. Fuel filter: Filter impurities and moisture in the fuel to protect the engine from contamination.
4. Fuel injector (nozzle): Injects fuel at high pressure into the combustion chamber of the engine to achieve precise fuel metering and atomization.
5. Fuel pipeline: Connect various components of the fuel system, including the fuel tank, fuel pump, filter, and injector.
6. Fuel pressure regulator: regulates the pressure of the fuel system to ensure that the fuel injectors operate at the correct pressure.
7. Fuel preheater: Preheats the fuel in a low-temperature environment to improve its fluidity and ensure smooth engine start-up.
8. Fuel return pipe: Return unburned fuel or excess fuel to the fuel tank.
9. Fuel sensors and instruments: Monitor the pressure, temperature, and liquid level of the fuel system and provide them to operators or control systems.
These components work together to ensure efficient and clean delivery of fuel to the engine, and achieve precise combustion control, thereby ensuring stable operation of the diesel generator.
