COLUMBUS, Ind. (July 6, 2004) - Today Cummins Inc. (NYSE:CMI) announced another first for its off-highway engines slated for the January 2006 emissions standards. The QSM has been approved by the Vehicle Certification Agency (VCA) as compliant to the Stage IIIA standards for Oxides of Nitrogen (NOx) and Particulate Matter (PM). Cummins follows up a first to the Environmental Protection Agency (EPA) Tier 3 certification with a Stage IIIA European Union Index Approval from the VCA.

"With the VCA certification of the QSM off-highway engine, Cummins continues its commitment to clean air with another first. Cummins builds on its track record of delivering to both our customers and our commitments with this achievement," said Cummins Vice President - Industrial Customer Engineering, Bharat Vedak. "Cummins significant investment in the right technologies has enabled our success in meeting regulations in the European Union as well as the United States ahead of schedule."

"Cummins is committed to providing our customers solutions that maintain the lowest possible installation impact and the lowest possible cost," said Cummins Vice President - MidRange Engine Sales, Dave Crompton. "Our approach to changes in emissions requirements is to help our customers navigate the regulations - regulations coming with shorter time intervals between them. Cummins understands the unique challenges for OEMs with off-highway applications and believes that we are not only in the leadership position for the 2006 standard, but that the Cummins Stage IIIA architecture will extend into 2014 and Stage IV with the addition of aftertreatment. This gives our customers the maximum possible platform stability in the face of new requirements," he added.

Cummins met the challenge of the Stage IIIA reductions by utilizing its extensive expertise in combustion research. "With the certification of the QSM completed early, our development will focus on further improvements in fuel economy and reliability to exceed our commitments to customers," said Bharat Vedak.

The certified and compliant Cummins QSM Stage IIIA will go into production in July 2004 with its advanced in-cylinder combustion recipe and an identical footprint from its EPA Tier 2 predecessor which minimizes any installation impacts for OEMs. The 11-liter, six-cylinder engine is rated from 290 - 400 hp and utilizes the CELECT TM fuel system with advanced electronic controls.
