Columbus, Ind. (March 29, 2005) - Cummins Inc. (NYSE:CMI) today announced that it will meet the stringent U.S. Environmental Protection Agency (EPA) 2007 emissions standards for on-highway heavy-duty trucks by integrating the Cummins Particulate Filter with its current cooled-Exhaust Gas Recirculation (EGR) engine technology.

"We said that cooled-EGR emissions technology would be the foundation for our 2007 product line back in 2002," said Tom Kieffer, Cummins Executive Director - Marketing. "Providing stable engine architecture assures customers that the engine they are operating today will be the same basic engine in 2007, and gives them confidence in the performance, reliability and durability of the Cummins solution."

The Cummins Particulate Filter, developed and manufactured by Fleetguard® Emissions Solutions, a subsidiary of Cummins Inc., is designed to reduce particulate matter emissions by ninety percent from current levels. The Cummins Particulate Filter is designed to replace the existing vehicle muffler, adding minimal weight to the vehicle. Service requirements for the Cummins Particulate Filter can be extended as far out as 400,000 miles (643,783 km) for line-haul operations, minimizing the operating cost impact to trucking companies.

The 2007 engine will also feature a crankcase ventilation system from Fleetguard that virtually eliminates any oil carryover from the engine.

"Having the right technology and building upon our successful proven products gives Cummins a unique advantage to integrate the engine and Cummins Particulate Filter while providing the best value for our customers," said Kieffer. "We have great confidence that these engines will have the same industry-leading fuel economy in 2007 and will provide the best performance, reliability and durability of any engine in the marketplace.

"With over 9 billion miles of road experience accumulated by Cummins heavy-duty engines since 2002, customers are telling us that our engines are viewed as the best in the industry, providing the best fuel economy, performance and reliability today," he added.

Separately, Cummins announced the results of high-mileage engineering evaluations on its ISX engine that proves engine durability will also exceed industry expectations. "Customers certainly have confidence in the performance and fuel economy of our current products, and as a result of this analysis, can now be assured that any concerns about engine durability have been eliminated," Kieffer commented.
