WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
The sequential multi-port fuel injection (SFI) provides the fuel/air mixture needed for combustion in the cylinders. The 10 solenoid-operated fuel injectors:
- are mounted in the intake manifold.
- meter fuel into the air intake stream in accordance with engine demand.
- are positioned so that their tips direct fuel just ahead of the engine intake valves.
- are connected in series with the fuel rail pressure and temperature sensor.
- supply fuel from the fuel tank with a fuel pump mounted in the fuel tank.
A constant fuel pressure is maintained across the fuel injectors by the fuel rail pressure and temperature sensor. The fuel rail pressure and temperature sensor:
- is positioned upstream from the fuel injectors on the fuel rail.
