Car Fuel System Explained: Key Parts and How They Work Together for Engine: 

The fuel system in a car is designed to store, filter, and deliver fuel efficiently to the engine for combustion. Here are the main components and their roles:

1. Fuel Tank:

The fuel tank stores gasoline or diesel. It is typically made of metal or plastic and has internal baffles to reduce fuel sloshing during movement. It’s the starting point of the fuel delivery system.

2. Coarse Fuel Filter (Pre-Filter):

Located near or inside the fuel tank, the coarse filter removes large impurities and debris before the fuel enters the pump. It helps protect the fuel pump from damage.

3. Electrical Fuel Pump:

The electric fuel pump draws fuel from the tank and pushes it through the system under high pressure. It is usually located inside or near the fuel tank and is controlled by the vehicle's electronic control unit (ECU).

4. Fuel Pipeline:

Fuel lines or pipelines transport fuel from the tank to the engine. They are designed to handle pressure and resist corrosion. Both metal and rubber hoses are used.

5. Fine Fuel Filter:

Positioned after the fuel pump, the fine fuel filter removes tiny contaminants that could clog fuel injectors or damage the engine. Clean fuel is essential for proper engine performance.

6. Pressure Regulator:

The fuel pressure regulator maintains consistent fuel pressure in the system. It ensures the engine receives the correct amount of fuel regardless of driving conditions or load.

7. Nozzle Rail (Fuel Rail):

The nozzle rail is a metal tube that distributes fuel evenly to all injectors (fuel nozzles). It maintains constant pressure across all injectors.

8. Fuel Nozzle (Injector):

Fuel nozzles or injectors spray a fine mist of fuel into the combustion chamber or intake manifold. The ECU controls the timing and amount of fuel each injector delivers.
