Cummins announces '07 highway engine certification
COLUMBUS, Ind. -- Cummins says the U.S. Environmental Protection Agency has certified its heavy-duty and midrange truck engines under the 2007, low emission engine standard. Full production of the new engines begin today, says the company. The 2007 certified engines include the HD ISX and ISM, as well as the MD ISL, ISC and ISB. The engines are certified and compliant for 2007, using 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 VP and President of the Engine Business, "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.??The Cummins Particulate Filter, designed and manufactured by Cummins Emission Solutions, includes a diesel oxidation catalyst (DOC) and a diesel particulate filter to reduce particulate matter by 90 percent. The crankcase ventilation system features the Fleetguard coalescing filter, which captures and filters crankcase emissions, and returns oil directly to the sump. In order to be prepared for the anticipated medium duty engine share growth and the expected increase in HD engine demand by the end of first quarter 2007, Cummins intends to retain its entire permanent workforce at all of its North American engine manufacturing plants.
