LAS VEGAS, Nev. (February 2, 2010) -

Cummins Power Products, a joint venture with Cummins Inc. (NYSE:CMI), showcased a new QSB6.7 Power Unit ready for Tier 4 Interim low emissions in 2011 at the World of Concrete show, which opened today in Las Vegas. The QSB6.7 unit is believed to be the first Tier 4-capable Power Unit displayed with an integrated air-intake-to-exhaust aftertreatment.

With a maximum rating of 300 hp (224 kW), the QSB6.7 unit, powered by a Cummins QSB6.7 engine, introduces a “Package Proof” design, which retains the same installation space from current Tier 3 applications through to Tier 4 Final in 2014. This unique packaging approach gives OEMs the ability to engineer Cummins Power Products into their installation one time, providing significant cost savings.

The QSB6.7 Power Unit is the first in a new range of next-generation Power Units offered by Cummins Power Products to meet U.S. EPA Tier 4 Interim and European Stage IIIB off-highway emissions regulations that will take effect in January 2011. Power Units, often referred to as Power Packs, consist of a complete unit that is either enclosed or on frame rails to provide a solution for a mechanical power need. A complete Power Unit includes a minimum of a base engine, base rails, a cooling package, exhaust with aftertreatment and an air intake system. The Power Units power everything from brush chippers and rock crushers to dewatering pumps, irrigation sprayers, rail maintenance units, mud pump installations, agricultural harvesting machines, industrial vacuums, hydraulic systems and oil well rig drills.

Cummins Power Products Tier 4 interim technology solution for Power Units builds upon the proven durability and reliability of Cummins engines. Cummins also has the unique advantage in that it has designed and manufactured the critical engine subsystems and exhaust aftertreatment. The Tier 4 Interim units are integrated with the engine and both the Cummins Particulate Filter and Cummins Direct Flow™ air cleaner system by Fleetguard. Cummins Power Products then upfits and validates the complete Power Unit design to optimize the total solution. Cummins and Cummins Power Products ability to design, build and integrate a complete installation package means they can deliver the most dependable solution with the lowest cost of ownership.

“Today’s Tier 3 products have the same space claim as these new Tier 4 Interim products for Jan. 1, 2011, as well as our EPA Tier 4 Final products for Jan. 1, 2014,” said Jim Osborne, Vice President of Engines and Power Products for Cummins Bridgeway.  

“By planning ahead and utilizing the same space claim for Tier 3 through Tier 4 Final, our OEM customers have the opportunity to engineer in a Cummins solution once and not have to worry about the re-engineering work and cost through Tier 4 Final, which starts in 2014. This also allows our customers to use one supplier for tailpipe compliance so they can focus on other aspects of their machines.”         Cummins Power Products is able to be the first in the industry to display this product thanks to its collaboration with Cummins Inc. This enables the group to be a leader in the manufacturing, packaging and testing of Tier 4 engines and subsystems.

“This QSB6.7 Power Unit at the World of Concrete is an example of our Tier 4 Interim models and technology. Our Tier 4 Interim installation is ready to achieve a 90 percent reduction in Particulate Matter (PM) and a 45 percent reduction in Oxides of Nitrogen (NOx). As Cummins already announced, these technologies also allow our customers to achieve up to a 5 percent fuel economy improvement compared with Tier 3, depending on rating and duty cycle,” Osborne said.
