Cummins delivers EPA 2010 engines for recreational vehicles

Cummins has successfully delivered Heavy-Duty and Mid-Range engines certified to the Environmental Protection Agency (EPA) 2010 standards that provide better performance, better reliability and better fuel economy to the recreational vehicle industry. Cummins engines, which utilize Selective Catalytic Reduction (SCR) technology to meet EPA 2010 and California Air Resources Board (CARB) emissions standards, are in full production and are available with Cummins chassis partners. 

The complete 2010 engine lineup for recreational vehicle applications is comprised of the ISB6.7, ISC8.3, ISL9, ISX11.9 and ISX15, and meets 2010 emissions standards with a completely integrated and driver-friendly system. The 2010 suite of engines incorporate cooled Exhaust Gas Recirculation (EGR), a single VGT™ Turbocharger, a common Electronic Control Module (ECM) across all engines, and the Cummins Aftertreatment System with SCR technology. The ISB6.7 features a High Pressure Common Rail (HPCR) fuel system, which delivers a precise mixture of fuel at a constant pressure regardless of engine rpm. The Cummins XPI fuel system is featured on the ISC8.3, ISL9, ISX11.9 and the ISX15, and is capable of multiple injection events per cycle at ultra-high injection pressures.

"One of the key features customers expect from our products is strong performance," said David Koppenhofer, Cummins Executive Director - North American OEM Business. "Our SCR technology has been a major contributing factor in our ability to increase horsepower without an increase in the engine's size. Motorhome OEMs have confirmed that the engine installation does not require a change to the floor plan design," added Koppenhofer.

Leading to the full production of the EPA 2010 engines for all on-highway applications, Cummins has followed stringent product-testing protocol through which engines are rigorously tested for performance and reliability. Concurrently, Cummins has worked closely with its motorhome chassis partners throughout the development of its 2010 products to ensure success in meeting strict quality standards to provide the highest reliability for customers.

Cummins has utilized cutting-edge technology for testing through the use of automated data analysis. Cummins has equipped more than 200 vehicles in on-highway applications - including internal test vehicles and customer field-test vehicles - with a proprietary datalogger that has enabled Cummins to log nearly 240 different variables while the vehicle is in operation. This method of acquiring, processing and analyzing a constant feed of data has allowed Cummins engineering to immediately identify and address any potential issues prior to product introduction.

"Having over 8 million miles of real-world experience with over 80 customers prior to our 2010 engine launch has contributed to Cummins ability to deliver on our promise of better performance, reliability and fuel economy," noted Koppenhofer.

Since full production commenced in January, Cummins has produced and shipped over 45,000 EPA 2010-certified engines from its manufacturing facilities in Jamestown, N.Y.; Rocky Mount, N.C.; and Columbus, Ind. through the end of October.
