I do not know the displacement, but:

It has piezo injectors, 2 EGR logs, and a normal single Garrett AVNT.

Or at least the one I saw did.



I don't suppose we could know where you were lucky enough to see one Pat?

What benefit are the piezo injectors over what is currently in the duramax?

More importantly, what did the ECM look like and did you try and read it? :eek:

The ECM scheduled for the 4.5 (if it ever goes ahead) was VERY different...

Cheers

yup!

Cindy have Paul/Ross seen it yet? I saw a quick glimps of it in one of the 2500 Suburban promo videos, I think I posted it on the EFILive forum. Looked really strange; it was black, square, and had deep fins cast on it.

We took some pictures of the ECM at SEMA in 2007, and wrote down the part number that was printed on it. That's it until they hit the streets and we get an ECM for development purposes.

I read somewhere that the 4.5 has been placed on hold for 18 months and will possibly be scrapped completely. Surely it's not a good sign to see GM sell off the SEMA display model....from memory I think that auction is in the next couple of days.

What's an AVNT?

Um, I can safely say that is a HUGE not true. I don't know how long it's on hold but it is NOT scrapped. Unless they have tons and tons and tons of blocks stock piled for nothing.:eek:

Not sure if the Urea injection has been further explained, but here's the main principle being used MOST diesels will have to meet the FINAL Tier IV emission standards. It's also called SCR

http://www.agcocorp.com/E3/technology/howitworks.html

"An onboard diagnostic system monitors the Diesel Exhaust Fluid (DEF)/AdBlue level and indicates when to refill the tank.

DEF/AdBlue is a non-hazardous, high-purity, colorless solution containing 32.5% urea. The rest is deionized water.

Urea is made up of ammonia and carbon dioxide. It's used as an artificial fertilizer and it's found in cosmetics and other products."

DEF/Adblue will sell for approx. $3/gallon, and off AGCO's website, a 5 gallon tank will last for over 300gallons of fuel. So i'd expect the similar results in a onroad vehicle as well.

Just hope this "great" idea wont interfere with farmers paying for fertilizer or being put on the back burner or a waiting list for getting the fertilizer we need to feed America.

I was at the Louisville Farm show and some guy wearing a specifically colored shirt says just put water in it. Hell it doesn't know the difference. Just don't let it freeze in the winter.

My reply, "Oh okay." :D
