WARRENVILLE, Ill. — International Truck and Engine launched a new Web site for its Engine Group, alongside technical details for the companys mid-range I-6 family of MaxxForce Diesel Power engines

The new Web site www.InternationalEngines.com is an opportunity for the company to present a fresh look at the manufacturers engine group, which consists of its North American operations and South American subsidiary, MWM INTERNATIONAL.

Internationals I-6 family of MaxxForce engines will be made available for 2008 model year trucks. Built on Internationals I-6 architecture, the MaxxForce DT, MaxxForce 9 and MaxxForce 10, will serve as the next level of International diesel engines geared towards a wide range of vocational capabilities.

Internationals I-6 engines, especially the legendary DT, have a remarkable history of quality and reliability, said Jack Allen, president of International Engine Group. These engines have been the engine of choice in Class 6-7 commercial truck and bus applications for decades.

Focusing on reliability, Internationals team of engineers made evolutionary changes to the new engines for 2008-model-year trucks, but kept the basic engine components the same.

The design strategy of the new MaxxForce DT, MaxxForce 9 and MaxxForce 10 was to change as little as possible, carrying forward the proven technology and components of the current engine families, while building on our Green Diesel Technology experience with advanced emissions controls, said Persio Lisboa, managing director for the Inline Engine Business Unit with International.

For changes that did enter the design, the intention was to further improve reliability, added Lisboa. Foremost among these changes is a new wiring harness.

This new harness has a foam- over-molding that is tough as nails and holds a consistent shape, Lisboa said. The resulting product fits right every time. It is much easier to assemble, which improves first-time quality on our assembly line and makes the engines easier to service.

Other features of the MaxxForce I-6 engines include: an upgraded EGR system to reduce NOx without sacrificing fuel economy due to increased EGR cooling, improved EGR mixing, higher flow rates and reduced pressure drop; the closed-crankcase ventilation system with a centrifugal oil mist separator has no filters to change, making it maintenance-free; a new intake throttle helps raise exhaust temperature for active regeneration of the Diesel Particulate Filter and protects the DPF from high-temperature damage.

Beginning in January, MaxxForce engines become the signature powerplant for International brand on-highway Class 4-8 commercial vehicles. The MaxxForce DT, MaxxForce 9 and MaxxForce 10 are built exclusively at Internationals Melrose Park, Ill. engine plant.
