|The 2008 Duramax Diesel 6.6L V-8 Turbo.|
General Motors Corp. (GM) will invest $69 million in its DMAX diesel engine plant in Moraine, Ohio to manufacture a new Duramax 6.6-liter V-8 turbo diesel engine that will meet 2010 emissions standards. DMAX Limited is a joint venture between GM and Isuzu Motors Limited and was established as a diesel engine company in 1998.
The 2010 model year 6.6-liter V-8 Duramax diesel 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 current Duramax 6.6-liter V-8 is a four-valve high pressure common rail direct injection diesel currently equipped with a diesel particulate filter to meet 2007 emissions requirements. Available in GM’s Chevrolet Silverado and GMC Sierra heavy-duty pickups, the engine delivers 365 hp (272 kW) and 660 lb-ft of torque (895 Nm). It is also offered with increased power and torque for the Chevy Kodiak and GMC TopKick medium-duty applications.
Versions are available with 300 hp (24 kW) and 520 lb-ft (705 Nm) of torque, as well as a new 330 hp (246 kW) option with 620 lb-ft (840 Nm) of torque. The Duramax is also available in GM’s full-size vans, Chevrolet Express and GMC Savana.
GM first introduced the Duramax diesel in the US in the 2001 model year. GM’s heavy-duty pickup truck market share has jumped nearly tenfold in the seven years that Duramax engines have been offered.
In 2007, GM began offering a Special Equipment Option on the 6.6L Duramax for B20 biodiesel capability. (Earlier post.)
The investment includes renovations to the plant, new machinery and tooling to support manufacturing of the new diesel engine.
In the DMAX joint venture with Isuzu Motors Ltd., GM owns 60% and Isuzu 40%.
