Question

What do you understand by fuel delivery system/control in electronic fuel injection?

Hint:

Tip: EFI = sensors + ECU + injectors for precise fuel control!

Answer 1

The fuel delivery system in electronic fuel injection (EFI) is designed to supply the right amount of fuel to the engine cylinders at the right time.
Unlike carburettors, EFI systems use sensors, an electronic control unit (ECU), and injectors for precise fuel management.
Sensors monitor various engine parameters like air intake, engine temperature, throttle position, and engine speed.
The ECU processes this data and controls the injectors to deliver the correct amount of fuel under different driving conditions.
The fuel is injected at high pressure directly into the intake port or combustion chamber, ensuring better mixing with air.
This improves fuel efficiency, increases power output, and reduces emissions.
Overall, EFI fuel delivery systems provide accurate, automatic fuel control for optimal engine performance.
