Indianapolis, Indiana (April 23, 2009) -

Cummins Inc. (NYSE:CMI) today announced its on-highway engine lineup is ready to meet the new Environmental Protection Agency (EPA) regulations for fire and emergency applications. Cummins products and technology are on display at the Fire Department Instructors Conference (FDIC) in Indianapolis, Ind., from April 23 through April 25.

The new EPA regulations, which take effect January 1, 2010, are the most stringent in the world, with near-zero Oxides of Nitrogen (NOx) and Particulate Matter (PM) emissions levels of 0.2 grams and 0.01 grams per brake-horsepower-hour, respectively.

Cummins unveiled the new ISX11.9 Heavy-Duty engine. The ISX11.9 provides a compact and lightweight engine ideal for fire and emergency vehicles. The ISX11.9 will provide better reliability, performance and better fuel economy compared to today’s industry-leading ISM engine.

The ISX11.9 features the Cummins XPI fuel system, an enhanced cooled-EGR system, a single VGT™ Turbocharger and incorporates Selective Catalytic Reduction (SCR) catalyst technology together with the Cummins Particulate Filter that was introduced in 2007. Ratings for fire and emergency vehicle applications for the ISX11.9 are 365-500 horsepower (272-373 kW) and 1350-1625 lb-ft (1830-2203 N•m) of torque.

The ISX15 will also be available for fire and emergency vehicle applications. Sharing common cooled EGR, VGT Turbocharger, XPI fuel system, electronic controls and aftertreatment system with the ISX11.9, the ISX15 will be offered with ratings from 525-600 horsepower (392-448 kW), with torque outputs from 1650-1850 lb-ft (2237-2508 N•m).

The ISX15 features the XPI fuel system and a single overhead camshaft for 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 engine, and gains of up to nine percent as compared to competitive 2010 in-cylinder solutions are anticipated.

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 also announced its MidRange engines for 2010, which appear nearly identical to their 2007 counterparts with the addition of an SCR catalyst in the Cummins Aftertreatment System. Cummins MidRange engines deliver best-in-class reliability and fuel economy with best-in-class power-to-weight ratios.

The ISB6.7, ISC8.3 and ISL9 engines continue to feature a single Cummins VGT Turbocharger; the ISC8.3 and ISL9 engines also feature the XPI fuel system, as they have since 2007. The most predominant change for 2010 is that the MidRange engines will share a common Electronic Control Module (ECM) with Cummins Heavy-Duty engines, with increased input/output and processing capability for full integration of the Cummins engine and aftertreatment system.

Engine-braking capability on Cummins MidRange engines is provided by the VGT Turbocharger, and an optional compression brake is available for the ISC8.3 and ISL9.

Cummins ISB6.7 will be offered in fire and emergency vehicle ratings of 260-360 horsepower (194-269 kW), with peak torque of 660-800 lb-ft (895-1085 N•m). Cummins ISC8.3 will be offered in fire and emergency vehicle ratings of 270-380 hp (201-283 kW), with peak torque of 800-1050 lb-ft (1085-1424 N•m). The ISL9 will be offered in fire and emergency vehicle ratings of 345-450 hp (257-336 kW) and peak torque of 1150-1300 lb-ft (1560-1763 N•m).

“Cummins has a complete lineup of Heavy-Duty and MidRange engines ready to meet the 2010 near-zero emissions standards,” said Mike Apple – Director of Automotive OEM Business. “The engine offerings will provide better reliability, better performance and better fuel economy than today’s products, all of which are critical for our customers’ use in fire and emergency vehicle applications.”

All engines offer best-in-class reliability, performance, fuel economy and high power-to-weight ratios. In addition, maintenance intervals are maintained for low operating costs. All of Cummins 2010 on-highway MidRange and Heavy-Duty engines are compatible with long-life coolants and biodiesel blends up to B20.

Cummins on-highway engines for the U.S. and Canada are assembled in the U.S. at Cummins manufacturing facilities in Jamestown, N.Y.; Rocky Mount, N.C.; and Columbus, Ind. Manufacturing processes were verified on the assembly lines for field test units. Limited production will begin in fourth-quarter 2009, with full production beginning in January 2010.

Cummins Aftertreatment System for 2010 was also displayed. The 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. Vehicle 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 that will be readily available for customers. DEF will be available at all 20 Cummins distributors and over 187 locations by October 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.
