the Washington (D.C.) Auto Show, the U.S. Environmental Protection Agency
(EPA), together with the Department of Energy (DOE), Chrysler Group and
Cummins, recognized the new 2007 Dodge Ram Heavy Duty as the cleanest
mass-production diesel-engine pickup truck on the market.
in dealerships in March, the Dodge Ram Heavy Duty’s 6.7-liter Cummins
turbodiesel engine is the first to meet 2010 truck emissions standards
in all 50 states, and will be significantly cleaner than other pickup
trucks. It is the first BLUETEC vehicle from the Chrysler Group.
“This new technology is a significant validation of industry's ability
to meet 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.
The new 2007
Dodge Ram Heavy Duty engine uses a diesel particulate filter (DPF) to
virtually eliminate particulate matter emissions and an adsorber catalyst
to reduce oxides of nitrogen (NOx) by as much as 90 percent.
Dodge Ram Heavy Duty pickup truck with the new 6.7-liter Cummins turbodiesel
engine is the cleanest diesel truck available on the market,” said
Tom LaSorda, President and Chief Executive Officer, Chrysler Group. “Working
together with Cummins, Dodge is the only manufacturer to meet stringent
2010 emissions standards -- today. That’s great news for our Heavy
Duty customers – 80 percent of whom choose the diesel option.”
Heavy Duty trucks’ long-standing relationship with Cummins was established
in 1988 and continues to thrive with new, more powerful, more efficient
and cleaner turbodiesel engines. In Indiana late last year, Cummins produced
the 1.5-millionth diesel engine for the Dodge Ram.
like the one we have enjoyed with the DOE and the leadership shown by
the EPA on ULSD have provided the right environment for this technological
breakthrough,” said Tim Solso, Cummins Chairman and CEO. “We
continue to research and invest in technologies that ensure Dodge Ram
heavy-duty trucks equipped with the Cummins turbodiesel engine are as
clean as they are powerful.”
Emissions and Durability
to the NOx adsorber and the DPF, the 6.7-liter turbodiesel engine includes
other technologies to improve fuel efficiency and reduce unburned hydrocarbons.
exhaust gas recirculation (EGR) system combines with a uniquely designed
piston combustion bowl and a high-flow, electronically-controlled Variable
Geometry Turbocharger (VGT™), matching boost pressure with the
engine’s performance needs to reduce emissions and improve drivability
the exhaust system, a self-cleaning DPF and an oxidation catalyst reduces
particulate matter by a factor of 10. The emissions system is designed
for a government-certified 120,000 miles
