6.7L Cummins Turbo Diesel for Pickups (EPA 2010)


6.7L Cummins Turbo Diesel for Pickups (EPA 2010)

The Ram Heavy Duty pickup with the Cummins 6.7L Turbo Diesel offers outstanding horsepower and torque, with a proven combination of advanced technologies. Cummins proven 6.7L Turbo Diesel delivers unsurpassed torque, best-in-class low-end torque, and a best-in-class standard integrated exhaust brake, providing the legendary performance expected from Cummins. It builds on the long tradition of durability of the Cummins Turbo Diesel.

This engine is rated with 350 horsepower at just 3013 rpm. It achieves a peak torque of 800 lb-ft with the automatic transmission configuration, providing Ram Heavy Duty pickup customers with superior trailer towing and drivability. With 800 lb-ft of torque at 1600 rpm, power is increased across a wide speed range of 1200-2700 rpm. This delivers up to 46 additional hp at typical highway cruising speeds and the most low-end torque available in a heavy duty pickup.


The Cummins 6.7L Turbo Diesel continues to offer the most powerful integrated exhaust brake available in a heavy duty truck. Cummins best-in-class integrated exhaust brake, with a full 225 braking horsepower at the wheel, gives Ram Heavy Duty pickup customers more confidence while towing the heaviest loads down the most severe grades. Cummins proprietary sliding nozzle Variable Geometry (VG) Turbocharger is used as the integrated exhaust brake, making this unique capability standard on every Cummins 6.7L Turbo Diesel. Utilizing the VG turbocharger, the exhaust brake significantly improves control when towing heavy loads, such as pulling RV fifth wheels and horse trailers, providing added vehicle control and vehicle brake savings by using the engine for braking power. This extends the vehicle brake life, resulting in reduced total cost of ownership.

The 6.7L Turbo Diesel’s inline six-cylinder configuration results in fewer components than comparable heavy duty V8 engines. Fewer parts translates into fewer opportunities for things to go wrong. With this inline six-cylinder configuration, time spent on maintenance is kept to an absolute minimum, with easy access to all service points.

Cummins offers a broad range of integrated technologies and has the ability to choose the right technology for the right market. Cummins chose to use a NOx Adsorber Catalyst in meeting 2010 EPA emissions standards in the Ram Heavy Duty pickup. This innovative solution enables the 6.7L Turbo Diesel to be the only diesel engine in the heavy duty pickup market that meets 2010 emissions standards without using Diesel Exhaust Fluid (DEF), providing added convenience to personal use customers. In meeting these more stringent emissions standards, which were met three years ahead of the competition, the engine also utilizes a third-generation High Pressure Common Rail (HPCR) fuel system with pressure capability of up to 1800 bar (26,000 psi). This multi-injection-capable fuel system is then used to manage in-cylinder conditions to limit emissions. It is a highly flexible system that achieves a total package of high performance, low Noise, Vibration, Harshness (NVH), and reduced emissions. The engine uses cooled exhaust gas recirculation (EGR) and other air-handling concepts, including Cummins VG Turbocharger to give optimum boost level as a function of engine rpm and load. A particulate filter is also used to reduce particulate matter (PM) level by 90 percent of pre-2007 levels, virtually eliminating any visible black smoke and residue in the tailpipe.
The years of experience and stability of this engine and aftertreatment system gives the Cummins 6.7L Turbo Diesel the unique advantage of having more engines and more miles on the road than any other diesel engine in the heavy duty pickup market. Ram Heavy Duty trucks with the Cummins 6.7L Turbo Diesel are fully covered under a comprehensive warranty that shows how much confidence we have in its dependability and durability.

The maintenance interval has changed over the years on several items, however, the valve lash adjustment remains the same at 150,000 miles (240,000 km) and the fuel filter replacement remains at 15,000 miles (24,000 km). The oil change interval is 7,500 miles (12,000 km) and is duty cycle based. This interval will vary because the mileage will fluctuate based upon how the driver utilizes the vehicle. This engine uses an oil change monitoring system which will display a message on the vehicle information center that alerts the driver to change the oil.

Don't forget that your new Cummins 6.7L Turbo Diesel engine requires low-ash engine oil; failure to use this type of oil can result in serious damage to the exhaust aftertreatment system in your vehicle. Be sure to purchase engine oil that meets CES 20081 standards and has a maximum 1.00 mass % content of sulfated ash.

Due to the new EPA regulations, owners of MY07 and later Cummins 6.7L turbo diesel-powered highway vehicles must refuel only with Ultra-Low Sulfur Diesel (ULSD) fuel meeting a 15-ppm on-highway requirement. Use of all other fuels is prohibited and may result in damage to the engine and/or the aftertreatment system. Be sure to purchase your diesel fuel from a reputable fuel station. For most year-round service, a high-quality No. 2 diesel fuel that meets ASTM specification D-975 (0.0015% sulfur level) will maintain good performance. EPA requires retail fuel stations that carry and dispense LSD and ULSD to label the pumps with a Low-Sulfur Highway Diesel Fuel and an Ultra-Low Sulfur Diesel label.

In addition, diesel fuel sold for off-highway use should not be used in any Cummins turbo diesel engine. This is due to off-highway fuels not necessarily meeting the fuel cleanliness or lubricity requirements for on-highway fuel specifications. Use of such off-highway fuels can result in accelerated wear to fuel system components.

Keep in mind that your 6.7 liter engine is a sophisticated, fully integrated system. Some aftermarket products can jeopardize this system and cause severe power system, exhaust system and engine damage. For instance, there are a number of products that claim to enhance engine performance. These so-called aftermarket, "performance chips" may carry claims to increase horsepower, torque output, and/or fuel economy. These non-original chips can alter how the engine operates and their claims are neither authorized nor recommended by Dodge or Cummins. Keep in mind that your truck’s electronic control system can detect and store information about any modifications that increase horsepower, torque, and/or fuel economy. This information is stored in the system’s memory and cannot be erased – even if the modification is removed. Use of these unauthorized products can affect your warranty coverage.
