New V-8 diesel will meet EPA’s 2010 emissions standard

General Motors Corp. has outlined a $69-million investment at its DMAX Moraine (OH) Engine plant, in preparation for producing the new Duramax 6.6-liter V-8 turbo diesel engine.

DMAX is a GM joint venture (60%) with Isuzu Motors Ltd. (40%), established in 1998. Isuzu developed the Duramax engine, which has been in production at the Moraine plant since 2006.

The new Duramax V-8 turbo diesel is planned to meet EPA emissions standards that take effect in 2010. According to GM, it will use a selective, catalytic reduction NOx after-treatment system with a diesel particulate filter to help achieve the 2010 Tier 2 Bin 5 and LEV 2 emissions standards, and it will be compliant in all 50 states.

The investment includes plant renovations, new machinery, and tooling for manufacturing of the new diesel engine. GM indicated the updates would begin immediately.

"GM is committed to continuing to reduce fuel consumption and emissions across its portfolio and around the world. The 2010 Duramax diesel is an integral part of that transformation, as well as a component of GM's strategy to diversify vehicle energy sources," stated GM Powertrain v.p. – global manufacturing, John Buttermore. "This new investment demonstrates GM's commitment to continue to invest in technologies that reduce the impact of our vehicles on the environment, while maintaining performance attributes required by customers in the areas of towing and hauling loads."

HELLO, where have you been?

This snipit came out of my dealer publication last week. Sounds like a common theme.

Cummins to Use SCR

In order to meet 2010 Environmental
Protection Agency emission standards,
Cummins Inc. plans to incorporate
selective catalytic reduction (SCR)
systems on its medium-duty on-highway
engines. “SCR enables us to
extend our power range while maintaining
excellent fuel economy, maintenance
intervals and overall low cost
of ownership,” said Dave Crompton,
vice president and general manager,
Cummins MidRange Engine Business.
SCR technology makes use of the
chemical urea and a catalytic converter
to reduce nitrogen oxide (NOx)
emissions. The urea is injected into
the exhaust as it leaves the diesel particulate
filter (DPF), where the exhaust
heat breaks the urea down into ammonia.
The exhaust (with ammonia and
NOx) then enters the SCR chamber,
where it reacts with a catalyst to form
the final exhaust products of water and
nitrogen.

 

Obviously not reading that thread.
