EMISSION ACCOMPLISHED: GM’S NEW DURAMAX DIESEL
MEETS TIGHTER U.S. REGULATIONS
General Motors Corp.'s 6.6-liter Duramax V-8 diesel has been upgraded for 2007 to meet
the next round of U.S. diesel emission standards. The most significant change is the
addition of a particulate filter, which is teamed with a reduction catalyst and other
changes to the fuel system.
The upgrades allow the engine to meet regulations for diesel
engines that take effect in January, which require a 90%
reduction in particulate matter and 50% reduction in
oxides of nitrogen.
The filter traps diesel particulates in a honeycomb-
like ceramic “brick” after they travel through
an oxidizing catalyst. Remaining exhaust gases are
routed out through the exhaust system.
Regeneration is performed periodically to clear the
trapped soot. An onboard computer controls fuel
injection and oxygen content to adjust the
exhaust energy to the appropriate level to clean
the trap. Periodic servicing of the filter is
required to remove residual ash. To help minimize
accumulation, a low-ash engine oil is
used. In some applications, the regeneration
process will be controlled via a manual switch.
The new engine also features additional
combustion control, including a variable-geometry
turbo system, cooled (enhanced) exhaust gas recirculation
and closed-crankcase ventilation to reduce NOx.
The use of reformulated, ultra-low sulfur diesel fuel—which goes on sale nationwide
this fall—enables some of the new technologies to be used. Under the new rules, sulfur
content is limited to 15 parts per million (ppm) vs. the current standard of 500 ppm. Diesel
engines made prior to 2007 can continue to use the higher sulfur blends.
GM co-developed the powerplant with Isuzu motors Ltd. The partners make it at their
Dmax Ltd. joint venture plant in Moraine, Ohio. The engine is used in variety of vehicles
above the 8,500-lb GVW limit, where heavy-duty emissions standards take effect.
Applications include the Chevrolet Kodiak and GMC Topkick medium-duty pickup trucks,
and 3/4-ton versions of the Silverado pickup. The standard engine is rated at 300 hp and
520 lb-ft of torque and has a high-output option that makes 330 hp and 620 lb-ft of torque.

Does this mean it takes 30 horsepower to operate the new stuff? Howard

This is not the same engine they will be using in the light duty pickups...Kodiak and Topkick

I have an '07 Classic which outputs 360 hp and 650 lb torque, so something is causing a 30 hp and 30 lb reduction in the new to be engine. :)

Hope this isn't accurate but it looks like it includes the 3/4 ton pickups.

It is a sad day for diesels everywhere....emissions testing:(
I wish one day all diesel and muscle car fans can run their cars w/o fear of the government stepping in.
And I didn't just learn of the emissions, this is just my first post about it.
\End Rant\

It is a sad day for diesels everywhere....emissions testing
This latest version of the Duramax, which will meet the 2007 EPA standards, doesn't mean that your locale will start testing it - or other diesel vehicles - for emissions compliance if they aren't already testing them. Diesel engines have had to meet certain emissions standards for years now; this is just another step. Whether or not they are tested is decided by local and/or state officials, usually due to areas being classified as 'non-attainment' areas by the EPA.

Diesel particulates are among the most harmful pollutants. I like breathing nice air...

Hope this isn't accurate but it looks like it includes the 3/4 ton pickups.

I have an '07 Classic which outputs 360 hp and 650 lb torque, so something is causing a 30 hp and 30 lb reduction in the new to be engine. :)



The NEW 2007 LMM diesel Engine will still have 360 hp and 650 lb torque just like your 07 classic.

I don't doubt you for a minute, I was just responding to the post above mine. I don't know where their information came from. :)

First rule of reading any specifications, look for the asterisks*

"* Final advertised power ratings will be announced later this year."

It is not set in concrete yet!

Serious Haulers
Detroit 3 ready diesels that boost horsepower
9/14/06

Forget the high fuel prices -- Dodge, Ford and General Motors this fall are powering up their diesel truck lineups.

Dodge: The 2500 and 3500 lines get a 6.7-liter Cummins turbodiesel with 350 hp and 650 lbs.-ft. of torque.
Ford: The Super Duty gets a 6.4-liter Power Stroke turbodiesel with at least 350 hp and 650 lbs.-ft. of torque.

GM: GMC and Chevy trucks get a Duramax with at least 360 hp and 650 lbs.-ft. of torque.
Despite tougher emissions rules coming in January and high fuel prices, the diesel-truck horsepower wars roll on.

Ford, Dodge, Chevrolet and GMC plan to offer new or revamped diesel engines for their highly profitable heavy-duty pickups in 2007. It's the last segment of the market where the Detroit 3 has no foreign competition.

General Motors and Ford Motor Co. will use the Texas State Fair in Dallas this month to officially announce horsepower and torque ratings for their new diesel engines. Buyers of diesel trucks pay close attention to power ratings because the higher the power, the greater the load the truck can tow or haul.

Texas is a key venue for such news because it's a coveted bellwether market for pickups.

GM and Dodge trucks go on sale in January as 2007 models, while Ford's Super Duty is set to debut in the first quarter as a 2008 model. The GM and Ford trucks are redesigned and re-engineered.

Dodge will have the biggest engine but the fewest cylinders. The inline six-cylinder Cummins turbodiesel, optional in the Dodge 2500 and 3500, grows from 5.9 liters to 6.7 liters. The increased engine size brings more power. Horsepower is rated at 350; torque is 650 pounds-feet. That's up from 325 hp and 610 pounds-feet of torque in 2006 models.

Ford plans to replace its current 6.0-liter Power Stroke V-8 turbodiesel with a 6.4-liter engine loaded with technology such as piezo-electric fuel injectors, which help reduce emissions and enable the engine to run smoother and quieter.

Ford plans to announce horsepower and torque ratings Sept. 28 when the Super Duty debuts at the Texas State Fair. But a Ford source says the new engine will develop at least 350 hp and 650 pounds-feet of torque, the same as the Dodge Ram.

The outgoing 6.0-liter engine is rated at 325 hp and 570 pounds-feet of torque.

"Maintaining power and torque leadership is important to us," says Charlie Freese, GM's executive director of diesel engineering.

Freese says the power of GM's Duramax engine has enabled the automaker to increase its share of the diesel-truck market from less than 2 percent in 2001 to about 33 percent today.

GM says the 2007 Duramax will have at least 360 hp and 650 pounds-feet of torque.

GM spokesman Susan Garavaglia says the final figures won't go down but could go up.

Tizeye-
Read Elvis Knows' Post:

:ro)

I don't recall saying the they would go down or up. Just that it was not set in concrete. ;)

All power to Duramax if they maintain or increase the output and comply with the new emission standards that you guys have to deal with. But knowing the enginuity of the people on this forum, there will be a workaround to disable all this junk within 3 nanoseconds of the trucks release!! :muahaha:

Hahaha.
Yeah I definately think your right about that Brett.
That will be one of the first things I do on my 2007 HD Duramax, (of course that will probably be after I install the 11" CST lift and the 38" Toyo Mud tires.)
