DESCRIPTION AND OPERATION
Engine
WARNING: Do not operate the engine with the hood open until the fan blade has been first
examined for possible cracks and separation.
The 4.6L (4V) (281 CID) Cobra engine is a V- 8 with the following features:
z intercooled supercharger
z dual overhead camshafts
z four valves per cylinder
z sequential multiport fuel injection (SFI)
z an aluminum intake manifold
z aluminum cylinder heads
z a cast aluminum, 90-degree V- cylinder block
z individually chain- driven camshafts with a hydraulic timing chain tensioner on each timing chain
z the electronic ignition system with eight ignition coils
Identification
Always refer to these labels when replacement parts are necessary or when checking engine
calibrations. The engine parts often differ within a CID family. Verification of the identification codes will
ensure that the correct parts are obtained. These codes contain all the pertinent information relating to
the dates, optional equipment and revisions. The Ford Master Parts Catalog contains a complete
listing of the codes and their application.
Code Information
The engine code information label, located on the side of the valve cover and the front side of the
valve cover, contains the following:
zengine build date
z engine plant code
z engine code
Exhaust Emission Control System
Operation and necessary maintenance of the exhaust emission control devices used on this engine is
covered in the Powertrain Control/Emissions Diagnosis (PC/ED) manual.
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:
z are mounted in the lower intake manifold.
z meter fuel into the air intake stream in accordance with engine demand.
