ORLANDO, Fla. (February 4, 2008) - Cummins Inc. (NYSE:CMI) announced today, at the 2008 Technology and Maintenance Council (TMC) Annual Meeting, the availability of Clean Idle Certified on-highway engines, meeting the new California Air Resources Board's (CARB) idle reduction regulation. The Cummins full lineup of on-highway engines, including the ISX, ISM, ISL, ISC and ISB are available to meet this new regulation by generating less than 30-g/hour NOx emissions at idle.


Effective immediately, Cummins customers can now specify a 50-state Clean Idle Certified engine option when ordering a new vehicle. In addition, customers now also have the option, through their local Cummins distributor, to update existing 2007 engines to meet the 50-state Clean Idle Certified status.


Cummins ability to offer Clean Idle engines complements and supports other available electronic engine features such as the programmable idle shutdown timer. Together these features help reduce a customer's idle time and fuel consumption, thus, only allowing idling for those periods where a driver needs cab comfort while logged out of service.


"We are very pleased to announce the availability of our Clean Idle Certified on-highway engines, said Jeff Jones, Vice President - Sales and Market Communications. "Cummins ability to offer these products demonstrates our strong commitment to customers and the environment."
