LESSON 1: OVERVIEW

Engine - 5.4L

5.4L 3-Valve Triton Phaser

The 2005 Expedition and Navigator are available with one engine:

•

New for 2005, the 5.4L 3-valve Triton V8.

– 300 horsepower @ 5,000 rpm

– 365 lb-ft of torque @ 3,750 rpm

– Variable cam timing

– Three valves per cylinder

–Electronic Throttle Control (ETC)

Rather than focusing on a single item to gain improvements in power, Ford used an approach that included

advancements on multiple fronts. These improvements contribute to overall power with reduced NVH, at low

engine speeds. Some of these changes are outlined below:

•

The three-valve design achieves same benefits as a four-valve design.

– Three-valve design balances the forces generated by the valve and spring movement.

– Reduces engine noise.
