International Truck and Engine Corp. says its Brazilian subsidiary, MWM International Motores, and Brazil-based supplier Tupy, will provide compacted-graphite iron cylinder blocks for the new MaxxForce 11 and MaxxForce 13
big bore diesel engines.
Tupy will cast the advanced CG Iron cylinder blocks at its plant in Sao Paulo, Brazil, and MWM International will machine the blocks at its Santo Amaro plant, also in Sao Paulo. The machined blocks will be shipped from South America to International's new engine plant in Huntsville, Ala., where the MaxxForce big bore engines will be assembled.
"Our ability to source globally and utilize MWM International for the machining of this new innovative block design demonstrates our commitment to integration and growth as a global company," said Persio Lisboa, vice president, purchasing and logistics, International Engine Group. "This also allows us the opportunity to leverage our assets to serve the North American market, while creating a competitive advantage for our MaxxForce big bore engines."
In late 2006, Huntsville was selected as the site for the assembly of the new engines. To accommodate the work, a new state-of-the-art plant is being built near International's current manufacturing facility in Huntsville. Production in Huntsville will begin in spring 2008. Initial engines will be partially assembled in Germany and finished and trimmed in Huntsville.
