Induction System
WARNING: This page is about a different car, the 2009 Lincoln MKZ. 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 6 solenoid-operated fuel injectors:
- are mounted between the fuel rail and 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.
