Found this little article today, thought it was interesting.

Man, I love the part in the article, where it states "GM is transforming its product portfolio to reduce fuel consumption and emissions". Now thinking of that DPF they have inplace which pours out more fuel to clean out the unit. go figure.

So , I guess we'll alll have to buy another one then so we can have the latest and greatest stuff??

i hate emissions

finally some news on the new duramax, intresting to see that it will stay with the same displacement, i guess that destroys the rumors that the duramax was moving to a 6.9 displacement. can't wait to see what kind of power it will produce.

i hate emissions


I hate emission controls. :):):)

I hate the EPA....:cool:

AAAAMEN!!!!!

ah the good old EPA idiots. slightly reduce the emissions per gallon yet those modifications require that you use more gallons to accomplish the same task.

GM developed the 6.6-liter Duramax along with Isuzu. It went on sale in the 2001 model year and has been a trouble-free, hardworking power plant that propelled GM to more than 25 percent of the heavy duty diesel truck market,

Haha, i guess they didnt hear about the LB7 injector issues or the LLY overheat issues. Lol, still awsome trucks though.

haha thats true, atleast it has been alot more trouble-free then the powerstroke.

According to the local news this is going into the Moraine Ohio plant, not the New York plant.

http://www.whiotv.com/news/15222139/detail.html

The article states it is the 6.6 liter going in there not the 4.5.

The 4.5 is going to be built in New York, and the 6.6 will still be built in Ohio.

I am still waiting to see what kind of mileage it will get.

too bad the new heavy duty dmax (not the 4.5) needs urea/SCR to meet 2010 regs. :rolleyes:

the 6.7 ctd meets 2010 regs without the use of urea. Why cant GM figure that one out? Could'nt they increase displacement (says its still going to be 6.6) to improve emmissions and maybe meet 2010 regs without SCR?

Granted, but the Cam timing greatly reduces power over 2700.
Combined with a 3rd inj event for combustion ATDC .........

So the new d-max is costing 69M to upgrade the plant, not the d-max itself. Alot more than 69M will be needed to upgrade the d-max. GM will be taking a step back IF the new d-max has to use urea, when others on the market don't. I love me d-max, but the 6.7 CTD is a heck of motor, Brother in laws is pretty nice. If Cummins can do it, GM should. Chris

This is all why I am puttin a 12v cummins in my 93 when I decide to restore it. Never came with a cat and will never need one as long as I stay in Gods Country (mid-west) and dont head to colorado or california.

Maybe Gm should of spent 69 mil on engineering a light under the hood so we can see WTF we r doing in the dark.

did we get the same duramax ,''relibile and trouble free'',

yeah for 69 mil i hope my next 50k truck will have a light under the hood!!!!

The 6.7 uses precious metals to meet the 2010 emissions so that will get pricey here in a while when prices of those metals go up because of their availability so maybe UREA ain't such a bad idear....

I wonder what will happen with the diesel engine it may price itself out of the market before it really becomes popular a duramax is $7000 dollar option and will only be getting more expensive. Diesel is 50 cents more a gallon. The gas mileage isn't much better than a gasser.

Most people still think diesel's are still slow and stinky

Which is exactly why I drive one. It's true; you are what you drive... :p:

wait..... what is UREA??

True, but :funnypost

from what I understand urea is a chemical that when injected after the turbo chnages NOx into amonia which is readily dissipated (sp) into the air. In other words instead of producing NOx the new trucks will now smell like small chicken houses going down the road.

The amonia is in the urea - it doesn't turn into amonia. What urea injection does is change NOx into Nitrogen (N2) and water, both of which are obviously harmless to the environment. Shouldn't be any odor to it.

The urea sure is a nasty fluid thats for sure, likes to oxidize things.

so like can you pee in the (urea thank) to fill it up;):D:D:D:grd:

I hate the EPA....:cool:


if it wasnt for the EPA, all these idoits at the backyard car shops would still be releasing refrigerant into the air....

[b]no More Black Smoke

wonder how much gm spent to make the 6.6 duramax?

didnt gm just buy it from isuzu?

not sur, maybe someone knows

human piss might not be strong enough, but cat piss on the other hand might work

if you have any strays you may want to set up a cat-piss-milking operation

didnt gm just buy it from isuzu?
yes

if it wasnt for the EPA, all these idoits at the backyard car shops would still be releasing refrigerant into the air....

.......Guess what the EPA has there eyes on next....... black diesel smoke... so enjoy it while you can. :D

Ya well I'll tell them to go chase the 300 trains that go through our town that smoke and have loads of coal releasing coal dust and see what they say.

I am so glad that I read this. I've been telling my wife for years that all of this cat piss that I've collected was going to come in handy. You don't know how many times I've almost tossed it along with the 378 litter boxes I've been storing it in.

I guess I'm just lucky, things always have a way of working out for me.


What do you guys think it will be worth? Is it sold by weight or by volume? I should start a web site mypudycatwee4sale2u4urgreendizl.com

Posted by Autoweek: "GM said it is spending $69 million in plant upgrades, which will include new production equipment." I am lost as to how you can justsify spending that much money to get just a hair bit more economy out of an engine O wait now they can over charge the consumer so that the EPA can sleep better. Cool article gentleman.

didnt gm just buy it from isuzu?


Yes but :

When they bought the engine they took there engineers and and they had a hell of a budget to make it better.
So they did a number of improvements and thought they were done but GM said you still have money so do MORE and they did.
I well try find the article ... I remember it well cause the engineers had a hard time using the budget cause the engine was allready fine tuned and didn't require tweaking.

GM will be parting ways with Isuzu if I remember correct model year 2010 or 2011 and will again be building their own diesel. I heard this at work today and was told this is do to Toyota signing with Isuzu for a diesel for their truck. If GM builds a diesel on their own as they did before that would be the dumbest thing they could do. We supply emission parts to almost all auto makers and we are currently prototyping parts for the new diesels.

Please tell me they are about to do away with dpfs

We don't make the DPF's, our main focus is the EGR and Turbo systems.

Please tell me they are about to do away with dpfs

No such luck. the DPF is here to stay, I'm afraid. Just like catalytic converters and EGR! :(

Hope they keep developing with Isuzu and don't run off on their own. Still remember when working with Porsche and VW to develop the Corvair engine they went off on their own, took a potentially great air cooled engine and turned it into a turd.
