DEARBORN, Mich., Jan. 26, 2011 The block, pistons, turbos, crankshaft, valves and other inner tools of a 3.5-liter F-150 EcoBoost favourite engine are still within firm bureau specifications after fast contrast that unnatural 10 years of wear or about 160,000 miles.

In an rare and high-stakes open reveal, Ford engineers messy a engine for a initial time in front of a live assembly of scarcely 1,000 during a North American International Auto Show (NAIAS) in Detroit.

I was vacant that, first, a engine looked as good as it did, and second, Ford took a possibility of opening it adult in front of a public, pronounced Gary Heinz, coordinator of a Automotive Student Service Education Training module during Henry Ford Community College in Dearborn.

You know that in a Detroit crowd, there are a lot of automobile mechanics who know a good engine from a ragged out one, pronounced Heinz, a long-time engine automechanic who watched a teardown with a organisation of students.

Heinz pronounced he credits a engine design, a high-quality production routine and a accurate tolerances between a relocating tools with a low wear found on a components.

Over a past 3 months, EcoBoost engine No. 448AA achieved a array of severe events to infer out a new technologys durability. Specifically, a engine hauled 55 tons of lumber, ran during full stifle for 24 true hours towing 11,300 pounds, kick competitors incomparable V8 engines in an ascending towing foe and finished a worlds toughest dried continuation race, a SCORE Tecate Baja 1000, in Mexico.

Said one spectator: Ford has a lot of courage to take this detached in public, generally after all that has been finished to this engine.

Ford powertrain technician Chris Rahill has ripped down scarcely 2,000 engines in his 20-year career during Ford Motor Company. He pronounced a engine he messy is not even tighten to being nearby a finish of a life.

Given a heated engineering and investigate and a astringency of a continuance tests we run that go into all Ford engines, Im not during all astounded how good this engine looked, pronounced Rahill. Everything was within production specification. Nothing was out of a norm.

Back to a dyno lab
After completing a SCORE Tecate Baja 1000 in only over 38 hours, a engine was pulled from a competition lorry and sent to Dearborn for analysis. There it constructed best-in-class 420 lb.-ft. of torque and 364 horsepower one horsepower reduction than a strange number.

The formula on a dyno reliable that a EcoBoost lorry engine still delivered superb energy even after a impassioned use this engine had been subjected to, pronounced Phil Fabien, Powertrain Operations.

The dyno and teardown events are prisoner in a final part of a web-based documentary that goes live currently during The documentary array explores a engines durability.

Key commentary associated to a continuance of a 3.5-liter EcoBoost lorry engine detected during a teardown include:

  • Turbochargers: No visible issues with a compressor or turbine, that rotated freely
  • Pistons: Rings spun openly and pistons showed no apparent signs of wear
  • Carbon deposits: Nominal. Carbon deposits can change formed on peculiarity of fuel used and when in a cycle a engine was stopped
  • Cylinder leakdown test: The engines cylinders are pressurized with 100 pounds of atmosphere to magnitude a sealing opening of a rings and valves. The cylinder leakdown exam formula ranged from 6 percent to 13 percent. That’s good within production tolerances, and as demonstrated by a dyno test, had no outcome on a engine’s performance.

Why a EcoBoost engine was so clean
The analogous miss of engine sludge/grime indicates that a engines PCV (positive crankcase ventilation) complement and a endorsed Motorcraft 5W-30 fake mix engine oil accessible off a shelf worked in peace to minister to purify engine operation.

The PCV complement radically recycles crankcase gases behind into a intake for reburning, that contributes to softened fuel economy and reduce emissions.

In terms of oil consumption, a 2011 F-150 EcoBoost has a 10,000-mile oil change interlude and includes an intelligent oil life guard (IOLM). The IOLM uses tangible engine and car handling conditions to some-more precisely calculate expected use intervals, depending on car handling conditions, as follows:

  • Up to 10,000 miles: normal travelling with highway driving
  • 5,000 to 7,500 miles: trailer tow/high-load driving
  • 3,000 to 5,000 miles: short-trip usage, impassioned temperatures

Instead of regulating a fixed interlude report (either by time or mileage), a IOLM tells customers, formed on their pushing habits and engine handling conditions, when to change a oil by elementary communications in a summary center.

Intense contrast pivotal to durability
The F-150 EcoBoost engine saw a initial movement on a dyno in July. Engineers punished it in heat and bucket extremes simulating a fast worse than any customers.

In a initial dyno test, we accelerated real-world mileage or engine cycles, pronounced Fabien. We ran during many aloft engine speeds and aloft torque levels and combined in some-more impassioned heat swings than a patron can presumably do. We can go from minus-20 coolant heat to 235 degrees within 3 mins during rise power.

Essentially, with these accelerated tests, we can run conditions business might be means to get into for a brief duration of time, though we do it for hours on end.

After a dyno testing, many engines would be prepared to be rebuilt or retired, though a EcoBoost woe exam was only beginning.
