Description

Today at 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. Available 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. ?The 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.? Dodge Ram 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. ?Partnerships 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.? Improved Emissions and Durability In addition to the NOx adsorber and the DPF, the 6.7-liter turbodiesel engine includes other technologies to improve fuel efficiency and reduce unburned hydrocarbons. A cooled 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 Within 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 A new closed crankcase ventilation system eliminates crankcase fumes and oil carry-over, a common problem with past diesels As durable as it is powerful, the 6.7-liter Cummins turbodiesel has life-to-major overhaul intervals of 350,000 miles, providing more than a 100,000-mile advantage over the competition. Nearly 40 percent of the new engine?s parts are carryover, with modifications geared to surpass emissions standards and increase horsepower and torque, while maintaining the durability associated with Dodge and Cummins.
