Induction System
WARNING: This page is about a different car, the 2003 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The fuel needed for burning in the cylinders is provided by a returnless, sequential multiport fuel injection (SFI).
- Fuel is supplied from the vehicle fuel tank by a high-pressure electric fuel pump mounted in the fuel tank.
- The fuel is filtered and sent to the fuel injection supply manifold.
- Fuel pressure is regulated by modulating pump output based upon readings from the fuel pressure sensor, located on the fuel rail.
- Fuel is metered into the intake air stream in accordance with engine by six solenoid-operated fuel injectors mounted in the lower intake manifolds.
- The six fuel injectors are mounted above the intake valves and connected in series with the fuel pressure regulator.
