WASHINGTON--(BUSINESS WIRE)--Cummins Inc. (NYSE:CMI) today unveiled the strongest, cleanest, quietest
best-in-class 2007 Cummins Turbo Diesel. Leapfrogging the competition,
the Cummins 6.7-liter Turbo Diesel engine, used exclusively in Dodge Ram
2500 and 3500 Heavy Duty pickup trucks, has increased displacement
providing increased horsepower and torque while achieving the world’s
lowest 2010 Environmental Protection Agency (EPA) NOx standard a full
three years ahead of the requirements.
The new Turbo Diesel engines are in full production at the Cummins
MidRange Engine Plant in Columbus, Ind. Cummins has been the sole
supplier of diesel engines for the Dodge Ram since 1988, shipping
approximately 160,000 engines in 2006.
Cummins is the first diesel engine manufacturer to have a product
certified to the 2010 EPA heavy-duty engine standards for oxides of
nitrogen (NOx) and particulate matter (PM) emissions, making it the
cleanest heavy-duty diesel engine available in North America. The 2010
EPA standards for NOx (0.2g) and PM (0.01g) represent a more than 90
percent reduction in each pollutant, compared to the 2004 standards.
“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.”
This new technology is a significant validation of the industry’s
ability to meet the EPA’s 2010 clean diesel
standards. These innovations help power our economy and drive our
environmental successes,” said Bill Wehrum, EPA’s
Acting Assistant Administrator for Air and Radiation.
Cummins announced this news prior to the Washington Auto Show in
conjunction with DaimlerChrysler and the EPA.
Strongest. The increased displacement of the 6.7-liter Turbo
Diesel – enabling an increase in horsepower
and torque while maintaining fuel economy –
will provide Dodge Ram customers with better engine performance without
sacrificing the reliability and durability that have become synonymous
with Cummins. Increased vehicle control and lower operating cost are
both delivered on the new 6.7L Turbo Diesel with the addition of an
integrated exhaust brake option, providing outstanding braking
performance.
Cleanest. Combining advanced in-cylinder technologies, including
a Bosch flexible 1800-bar High Pressure Common Rail fuel system with
Cummins next-generation cooled Exhaust Gas Recirculation (EGR) and
Variable Geometry Turbocharger (VGT™), plus
advanced exhaust aftertreatment technology, every Dodge Ram pickup will
comply with the 2010 NOx and PM emissions standards. The advanced
aftertreatment system includes a close-coupled diesel oxidation
catalyst, a NOx adsorber catalyst and a combined diesel
oxidation/particulate filter. The engine also incorporates a proprietary
closed crankcase ventilation (CCV) system to eliminate crankcase fumes
and “driveway drips.”
These advanced technologies require the use of Ultra-Low Sulfur Diesel
(ULSD) fuel in order to meet the tough 2007 and 2010 regulations.
Quietest. The 2007 Cummins Turbo Diesel achieves a 50 percent
noise reduction over the previous model, even with the increase in power
and torque. The combination of reduced combustion noise, a low-noise
VGT, optimized fuel timing/delivery, reduced-noise accessory drive
pulleys and block side shields all contribute to this significant noise
reduction.
Since 1988, Cummins and Dodge have collaborated to ship over 1.5 million
Heavy Duty diesel pickup trucks and today enjoy around 30 percent market
share in this highly competitive market in North America.
