2011 Ford F250 Super Duty 4x4 Custom Suspension 6.7 Powerstroke Diesel
http://bossrig.com - 2011 Ford F250 Super Duty 4x4 Custom Suspension 6.7
New truck seen at Frontier Ford in Sunnyvale/San Jose. The custom
suspension and wheels appear to have been done by 'Dealer Services'. The
price on the sticker with the mods included is about $65,000.
That's $62,000 more than I paid for my own F250 4x4 diesel.
These newer engines are so complex that I just stick with the classics, but
other folks are into newer trucks and willing to spend the money up front
and on expensive maintenance and expensive fixes so I'm happy to feature
them and sure do appreciate their looks and performance.
Here's some information on the new 6.7 Liter PowerStroke in this truck:
It's codenamed 'Scorpion'. First pickup diesel engine designed by Ford.
Totally new engine design that could be described as radical in how it
approaches meeting EPA requirements while still generating high power and
Unique turbo design which includes back
to back high and low rpm impellers and adjustable vanes capable of a form
of Exhaust braking available in tow
The turbo has a special ball-bearing
cartridge around the shaft .. faster spool up, a very solid
integral/centered base which routes oil and coolant to the turbo .. and this turbo system has it's own oil filter.
Two completely separate cooling systems; two radiators; two water pumps.
Two EGR coolers.
Diesel Particulate Filter, DPF System.
* The big change *
SCR = Selective Cataytic Reduction.
Alongside the fuel talk filler there is now a filler to replenish a supply
of 'diesel Exhaust fluid', a diluted
urea solution. (urea is a primary component of urine). A fine mist of this
fluid is injected into Exhaust gasses
to reduce NOx. Dodge Cummins is using a similar system while Duramax uses a
different approach to reducing NOx. It's predicted that most owners will
have to refill the urea tank about as frequently as oil changes. The SCR
system can also be referred to as a DEF (Diesel Exhaust Fluid) system.
Piezo electric fuel injectors can inject 5 times per stroke through 8
These are electrically actuated and supplied with high pressure fuel
through the Bosch common0rail system. It can reach up to 30,000 PSI.
This new engine has gone through and passed some very vigorous and extreme
testing in the areas of continuous heavy towing and hard driving patterns
as well as extreme temperature shock cycles of extreme hot and extreme cold
such as you might get running an engine hard in Alaskan cold, turning it
off for long enough just to let radiator coolant fall below freezing and
then freezing cold coolant hitting the still very hot engine after a stop
of a few minutes. Initial info sounds like they are testing very seriously
to try to overcome risks associate with a new design and bad experiences
with past PowerStrokes like the 6.0.
This engine is a LOT quieter than previous PowerStrokes, thanks to 'pilot
injections' .. 1 or 2 initial injection events of the 5 possible injection
events per stroke. This smooths out the combustion during a stroke and
reduces the sound dramatically.
This article gives more info on the sounds including link to YouTube video
demonstrating with/without pilot injection sound difference:
