Induction System
WARNING: This page is about a different car, the 2004 Lincoln Aviator. However, it is still accessible from the selected car via links, so may be relevant.
The sequential multiport fuel injection (SFI) provides the fuel/air mixture needed for combustion in the cylinders. The 8 solenoid-operated fuel injectors:
- Are mounted in the lower 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 pressure 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 pressure sensor. The fuel pressure sensor:
- Is positioned upstream from the fuel injectors on the fuel injection supply manifold.
