Induction System
WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The air/fuel mixture needed for burning in the cylinders is provided by the multiport fuel injection (MFI) system. Refer to INTAKE AIR, FUEL CHARGING, STARTING & ENGINE ELECTRONICS - 3.9L for additional information.
Fuel is:
- Supplied from the fuel tank by the fuel pump.
- Regulated by the fuel pressure sensor.
- Delivered to the injector supply manifold.
A dual damper has been added to reduce pressure fluctuations caused by the fuel injectors.
