Ramming Through 2010

Posted on January 31, 2007

Cummins Inc. has unveiled its newest Turbo Diesel engine for the Dodge Ram 2500 and 3500 Heavy Duty pickups and while it’s noteworthy for increases in displacement, horsepower and torque, what’s more significant is that the engines have been shown to meet the U.S. Environmental Protection Agency’s NOx standard a full three years ahead of the requirements, Cummins and DaimlerChrysler announced.

“This new technology is a significant validation of the industry’s ability to meet the EPA’s 2010 clean diesel standards,” said Bill Wehrum, EPA’s acting assistant administrator for Air and Radiation. “These innovations help power our economy and drive our environmental successes.”

The new engines, which are in full production at the Cummins MidRange Engine Plant in Columbus, Ind., integrate a range of technologies to meet EPA’s 2010 standards, most notably a three-section aftertreatment system that incorporates what is considered to be the first NOx adsorber catalyst on a production engine in the U.S. Other emissions reducing technologies include a new Bosch high-pressure common rail fuel system, a variable geometry turbocharger, a closed crankcase ventilation system and a diesel oxidation catalyst and soot filter.

“The application of the right technology on the Dodge Ram is an extension of the joint clean diesel development work Cummins and DaimlerChrysler have performed together for nearly two decades,” said Cummins President and Chief Operating Officer Joe Loughrey. “The new best-in-class Cummins Turbo Diesel and the Dodge Ram will provide the strongest, cleanest, quietest solution for heavy-duty pickup truck customers.”

More complete details on the 6.7 L, 350 hp engine will be available in the February issue of Diesel Progress.
