Delphi is a well-known manufacturer of diesel injector nozzles, commonly used in diesel engines for vehicles, industrial equipment, and other applications. While specific parts and components may vary depending on the injector model and application。

1. Nozzle Tip: This is the part of the injector that sprays the fuel into the combustion chamber. It's typically made of durable materials like hardened steel or stainless steel to withstand high pressures and temperatures.

2. Injector Body: The body of the injector houses various components and provides structural support. It contains passages and channels for fuel flow and is designed to withstand the pressures associated with fuel injection.

3. Needle Valve: The needle valve controls the flow of fuel through the injector nozzle. It opens and closes in response to signals from the engine's electronic control unit (ECU) to precisely control fuel delivery.

4. Control Valve: In modern electronically controlled injectors, the control valve regulates the movement of the needle valve. It's actuated by an electromagnetic coil and responds to signals from the ECU to precisely control fuel injection timing and duration.

5. Spray Holes: These are small openings in the nozzle tip through which fuel is sprayed into the combustion chamber. The size, shape, and arrangement of the spray holes influence fuel atomization and combustion characteristics.

6. O-rings and Seals: These components ensure a tight seal between the injector and the engine's fuel system to prevent leaks and maintain proper fuel pressure.

7. Nozzle Holder: The nozzle holder secures the injector to the engine's cylinder head or fuel rail and provides electrical connections for injectors with electronic control systems.

8. Filter Baskets: Some injectors feature filter baskets or screens to prevent contaminants from entering the injector and causing damage or clogging.
