Induction System

The sequential multiport fuel injection (SFI) provides the fuel/air mixture needed for combustion in the cylinders. The eight 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 drop 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.
