Houston, Texas (May 4, 2009) -
Cummins Inc. (NYSE:CMI) introduced its on-highway Heavy-Duty engine lineup ready to meet the new Environmental Protection Agency (EPA) regulations for the North American market. Cummins 2010 engine technology is on display at the Offshore Technology Conference in Houston, Texas, from May 4-7, 2009.
The new EPA regulations, which take effect on Jan. 1, 2010, are the most stringent in the world, with near-zero Oxides of Nitrogen (NOx) and Particulate Matter (PM) emission levels of 0.2 grams and 0.01 grams per brake horsepower-hour, respectively. Additionally, On-Board Diagnostics (OBD) will be required for the first time on heavy-duty diesel engines for on-highway vehicles over 14,000 pounds.
The featured ISX15 will provide better fuel economy, better performance and better reliability compared to today’s industry-leading ISX engine. The ISX15 features the Cummins XPI fuel system, an enhanced cooled-EGR system, a single VGT™ Turbocharger and the new Cummins Aftertreatment System that incorporates Selective Catalytic Reduction (SCR) catalyst technology together with the Cummins Particulate Filter that was introduced in 2007.
The XPI fuel system and a single overhead camshaft give the ISX15 an industry-leading power-to-weight ratio among big-bore engines. Fuel economy gains of up to five percent will be realized as compared to today’s ISX. Ratings will be maintained at 400-600 horsepower (298-447 kW), with torque outputs of 1450-2050 lb-ft (1966-2779 N•m).
The new Cummins ISX11.9 engine was also introduced at the show. The ISX11.9 provides a compact and lightweight engine that, like the ISX15, is ideal for workover rig applications. Sharing a common cooled EGR, VGT Turbocharger, XPI fuel system, electronic controls and aftertreatment system with the ISX15, the ISX11.9 will be offered with ratings of 310-425 horsepower (231-317 kW) and torque of 1150-1650 lb-ft (1559-2237 N•m). A 450-horsepower (336 kW) rating unique to workover rigs is also available. With superior response time and low-end torque, the ISX11.9 and ISX15 allow operators to pull pipe and service wells faster than anyone in the industry.
The ISX15 will continue to feature the Intebrake™, an integrated engine brake; and the ISX11.9 will be offered with an optional engine compression brake.
“Cummins Heavy-Duty engines have made their name with outstanding performance, fuel economy, reliability, durability and resale value,” said Steve Charlton – Vice President, Heavy-Duty Engineering. “Customers can count on our engines to be even better in 2010 in every regard. Our Heavy-Duty engines for 2010 have a large ‘sweet spot’ due to the low-temperature NOx conversion capability of the copper-zeolite catalyst, which means that these engines are extraordinarily driver-friendly. Fuel economy gains can be realized with even the most inexperienced driver and, at the same time, the engines deliver performance that the driver will love."
The ISX15 and ISX11.9 will include a new Electronic Control Module (ECM) with increased input/output and processing capability for full integration of the Cummins engine and aftertreatment system.
All of Cummins 2010 on-highway Heavy-Duty engines offer best-in-class fuel economy, reliability and high power-to-weight ratios. In addition, maintenance intervals are maintained for low operating costs for these engines as well as compatibility with long-life coolants and biodiesel blends up to B20.
Cummins Heavy-Duty on-highway engines for the U.S. and Canada are assembled in the U.S. at Cummins manufacturing facility in Jamestown, N.Y. Manufacturing processes were verified on the assembly lines for field test units. Limited production will begin in fourth-quarter 2009 and full production beginning in January 2010.
As part of Cummins integrated solution for 2010, the ISX15 and ISX11.9 will include the Cummins Aftertreatment System. This new system builds on the proven Cummins Particulate Filter, introduced in 2007 in North America, with a Selective Catalytic Reduction system. The SCR system adds a Diesel Exhaust Fluid (DEF) dosing valve, decomposition reactor for the hydrolysis of DEF, and a catalyst with copper-zeolite coating. Truck OEM-supplied components include the DEF tank and associated plumbing and heating. DEF, a new fluid that will be required for the operation of most 2010 diesel-powered vehicles, is an American Petroleum Institute (API) certified product and will be available at all 20 Cummins distributors and over 187 locations by Oct. 1, 2009. In addition, DEF will also be available through the extensive Cummins Filtration network, which includes over 20,000 locations with nearly 8,000 retailers in North America.
“Cummins investment in our 2010 engines demonstrates that we are in the North American on-highway markets for the long haul,” said Jim Kelly – President, Engine Business. “I am extremely confident in Cummins readiness for 2010 across all areas of our business. And I’m confident that, with our OEM partners, we’ll continue to deliver high-performance products that help our customers operate cost effectively and efficiently and, at the same time, reduce greenhouse gas emissions and dependence on foreign oil.”
