Zorluk: OrtaFuel and Air Intake Systems

In a modern electronic fuel injection (EFI) system, gasoline travels through several key components between the storage reservoir and the combustion chamber. Arrange the following components in the correct sequence through which pressurized fuel flows from the fuel tank into the engine.

  1. 1In-tank electric fuel pump
  2. 2Inline fuel filter
  3. 3Fuel delivery rail
  4. 4Fuel injector nozzle

Cevap

The correct sequence of fuel flow is: In-tank electric fuel pump → Inline fuel filter → Fuel delivery rail → Fuel injector nozzle.
Pressurized fuel flow begins at the in-tank electric fuel pump, which pressurizes fuel out of the fuel tank reservoir. It then flows forward through the inline fuel filter, where contaminants and debris are removed to protect the system. Clean, high-pressure fuel then enters the fuel delivery rail mounted across the engine, which acts as a common manifold distribution pipe. Finally, the fuel rail feeds the individual fuel injector nozzles, which electronically spray atomized fuel into the intake ports.

Adım Adım Çözüm

1
Identify the initial source and pressurization point of fuel in the delivery system.
The in-tank electric fuel pump is the first component in the circuit, drawing fuel from the tank reservoir and pumping it into the supply line under pressure.
Fuel must be pressurized at the storage tank to move forward through the fuel lines toward the engine.
2
Determine the protective filtration point in the pressurized supply line.
The inline fuel filter is positioned downstream of the pump along the chassis supply line.
Filtration must occur before fuel reaches precision engine-mounted components to prevent clogs and injector damage.
3
Trace the fuel into the manifold distribution component on the engine.
The fuel delivery rail receives filtered, pressurized fuel at the engine intake manifold.
The fuel rail distributes an even supply of high-pressure fuel across all engine cylinders.
4
Identify the final metering and atomization component that delivers fuel to the engine.
The fuel injector nozzle receives fuel from the rail and meters it into the intake runner.
Injectors are mounted directly into the fuel rail and act as the final gate to atomize fuel for combustion.
