Navistar on track with engines for 2010; final tests nearly done

Continuing on its path to meet the latest emissions requirements through its Advanced EGR (exhaust gas recirculation) MaxxForce engines, Navistar announced it is on track with its 2010 engine testing and will be prepared for a successful engine launch in the months ahead.

Navistar has completed rigorous testing and analysis in both its engine labs and field test units during the past 18 months. This past March, Navistar completed its final stages of cold-weather testing in northern Minnesota.

Final validation testing at high altitude and high temperature is being conducted in Nevada and the mountainous regions of Colorado. Navistar engineers are completing the final evaluation of engine performance in high elevations with aggressive inclines and declines. Now that the warm summer months are here, Navistar engineers will travel to desert-like conditions in Arizona and Nevada to complete its 2010 hot-weather testing. Navistar has more than 60 test vehicles in operation, logging thousands of miles each and every week. As testing and validation is finalized in preparation for launch, these 2010 test vehicles will have logged millions of driving miles in real-world conditions.

To meet the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) 2010 emissions standards for on-highway diesel engines, MaxxForce Advanced EGR engines will use proven technologies such as advanced fuel injection, air management, electronic controls, and proprietary combustion technology. Navistar’s 2010 certified product meets the CARB nitrogen oxide best achievable control technology (BACT) designation, assuring customers that Navistar’s products will meet their needs not just today, but also in the future.
