Induction System
WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
The SFI provides the fuel/air mixture needed for combustion in the cylinders. The 8 solenoid-operated fuel injectors:
- are mounted in the fuel injection supply manifold and the intake manifold above the cylinder heads.
- 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 regulator.
- supply fuel from the fuel tank by a fuel pump mounted in the fuel tank.
A constant fuel pressure drop is maintained across the fuel injectors by the fuel pressure regulator. The fuel pressure regulator:
- is positioned upstream from the fuel injectors on the fuel injection supply manifold.
