COLUMBUS, Ind. (May 11, 2004) - Cummins Inc. (NYSE:CMI) today reaffirmed its commitment to the North American construction and agriculture markets with its solutions for the Environmental Protection Agency (EPA) Tier 3 standards that take effect in January of 2005.
"Cummins has the right technology and global support network to provide our construction and agriculture customers with the best value in power solutions for their broad range of diesel engine applications," said Cummins Executive Director - Marketing Tom Kieffer.
"We have invested in upgrading our entire product line - across the 50- to 750-hp Tier 3 power band - to provide our construction and agriculture customers with the highest levels of reliability, durability, performance and dependability - at the lowest possible cost of operation," he added. "At the same time, we are committed to meeting or exceeding clean air standards."
Development work is well underway for all of the Tier 3 products, which will be launched ahead of the emissions introduction dates. Cummins engines will feature an in- cylinder solution with minimal OEM installation impact. Cummins 6-cylinder Tier 3 QSB will be available in June 2005 and the QSM Tier 3 engines will be available in July 2004, for emissions regulations beginning in January 2005.
The EPA has not set Tier 3 standards for engines of 50 hp or less, such as the lower range of the Cummins A Series, but they have proposed Tier 4. Tier 4 begins in 2008 for these engines. Engines greater than 750 hp will need to meet Tier 2 standards in the U.S. beginning in 2006.
Cummins has been able to optimize the in-cylinder combustion system to meet Tier 3 NOx levels without the need for aftertreatment or other hardware. In addition, the Cummins Tier 3 advanced combustion solution provides a stable equipment architecture through 2015 and beyond.
While there are many varieties and styles of fuel systems on the market today, having full electronic control over fuel timing, quantity, pressure, delivery rate shape and the number of injection events is a must for optimum emissions solutions and performance.
One such advanced system is the common-rail fuel system used on the latest platforms of the QSB/QSC/QSL/QSK19. This system has full control over the fuel injection event in relation to timing, quantity, pressure and number of injections. Cummins achieves Tier 3 emissions reductions even with high sulfur fuels, which allows for reliability anywhere in the world.
