Fuel Charging and Controls
WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
The fuel charging and control system consists of the:
- Throttle body.
- Fuel injectors.
- Fuel charging wiring.
- Fuel injection supply manifold.
- Fuel pulse damper.
- Fuel pressure relief valve.
The fuel charging and controls system is:
- A sequential, multiport fuel injection (SFI) system.
- Pulse-width modulated.
- Mass air flow (MAF) controlled.
The fuel injection supply manifold:
- Delivers fuel to the individual fuel injectors.
- Receives fuel from the fuel supply line.
The throttle body:
- Controls air supply to the upper intake manifold by positioning the throttle plate.
- Connects the accelerator cable and, if equipped, the speed control actuator cable to the throttle plate.
The fuel injectors:
- Are electrically operated by the powertrain control module (PCM).
- Atomize the fuel as the fuel is delivered.
- Are deposit-resistant and self-cleaning.
- Each have an internal solenoid which opens a needle valve to inject fuel into the lower intake manifold.
The fuel pulse damper:
- Reduces fluctuation of the fuel pressure during injector operation.
