Cummins Inc. has announced that the U.S. Environmental Protection Agency (EPA) has certified the Cummins heavy-duty and mid-range truck engines for 2007. Full production of the new engines begins this month.

The 2007-certified Cummins truck engines include the Heavy-Duty ISX and ISM, as well as the MidRange ISL, ISC and ISB. The engines are certified and compliant for 2007, using Cummins proven cooled exhaust gas recirculation (EGR) technology across the entire product line. To meet the more stringent 2007 emissions standards, which reduce particulate matter by 90 percent and also require a significant reduction in oxides of nitrogen (NOx) from 2004 limits, Cummins has added an integrated Cummins particulate filter and a crankcase ventilation system to the engines.
“With more than 400,000 cooled-EGR engines on the road, and well over 40 billion miles of experience, Cummins customers can be confident in the reliability and durability of these engines,” said Jim Kelly, Cummins vice president and president of Engine Business, “We are confident in the customer advantages provided by our 2007 engines and emissions solution. Field testing and limited production units have demonstrated the performance, fuel economy and maintenance intervals that will meet and exceed customer expectations.
The entire line features fully integrated electronic controls, with a single ECM (Electronic Control Module) that controls the engine and aftertreatment. All engines will use the patented sliding-nozzle Variable Geometry Turbocharger (VG Turbo), made by Cummins Turbo Technologies, which features an electric actuator for 2007 with faster response and improved precision in adjusting airflow to the engine.
