TAMPA, Fla. (February 12, 2006) - Cummins Inc. (NYSE:CMI) announced today that its MidRange on-highway engine product line for 2007 will offer enhanced performance while using proven, reliable technology to meet the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emissions standards for 2007 during the American Trucking Associations Annual Leadership Meeting in Tampa, Fla.
Cummins MidRange product line for 2007, including the enhanced ISL, ISC and ISB engines, will use Cummins proven cooled Exhaust Gas Recirculation (EGR) technology with the addition of exhaust aftertreatment provided by the integrated Cummins Particulate Filter and a crankcase ventilation system to deliver certified and compliant power. By using this common emissions solution across all on-highway engines, Cummins leverages its proven technology to meet 2007 emissions standards while at the same time delivering superior reliability and increased performance.
According to Dave Crompton, Cummins Vice President and General Manager of MidRange Engine Business, "Cummins Midrange engines have demonstrated every advantage for our customers - proven reliability, fuel economy, minimum maintenance and lowest cost of ownership. The number of customers running Cummins MidRange engines continues to grow, demonstrating their confidence that Cummins has the best solution for medium-duty and vocational trucks."
According to Jeff Weikert, Cummins 2007 MidRange Program Leader, "Our 2007 MidRange and Heavy-Duty field test units have already completed over 2.5 million miles in field testing that encompasses all altitudes, temperatures and conditions, and over 20,000 abusive test cell hours. We have shared our experience across platforms to create a very solid lineup. We believe customers will really like the increased performance of these engines."
The Cummins Particulate Filter and crankcase ventilation system are fully integrated with the engine to meet 2007 emissions standards. The Fleetguard® Enviroguard™ coalescing filter captures and filters crankcase emissions. Cummins is the only engine company with the key in-house technologies that enable the engine and aftertreatment system to be totally integrated for optimal reliability, performance, fuel efficiency and low cost of ownership. Both the engine and aftertreatment are controlled by a single ECM (Electronic Control Module).
The entire Cummins MidRange line will continue to use High Pressure Common Rail fuel systems - enhanced for 2007 with higher injection pressures to optimize fuel economy and increase performance. All engines will use the patented sliding-nozzle Variable Geometry Turbocharger (VG Turbo), which doubles as an exhaust brake with increased braking power in 2007. Also new in 2007, the VG Turbo features a new electric actuator with faster response and improved precision in adjusting airflow to the engine.
The ISB for 2007 will see displacement increase from 5.9 L to 6.7 L, providing more horsepower, more torque and, more importantly, more performance for customers. Enhanced electronic engine controls will increase the number of injection events per combustion cycle, so the ISB will continue its position as the fuel economy leader with the lowest total cost of ownership in its class. An automatic Oil Level Sensor option eliminates the need for daily oil level checks. And, a new 18-quart oil pan option allows for standard oil drain intervals to be increased to 20,000 miles (32,000 km).
The ISL, ISC and ISB all share an enhanced ECM with greater speed, memory and flexibility. The ISL and ISC both offer an optional compression brake.
Enhanced top horsepower/torque ratings for 2007 include: ISL 365/1250 (272 kW/1695 N•m); ISC 330/1000 (246 kW/1356 N•m); ISB 325/750 (242 kW/1117 N•m).
Customers will continue to benefit from Cummins superior ability to integrate critical subsystems for total performance and low cost of ownership. For 2007, fuel consumption and maintenance intervals are unchanged.
