Continuing on its path to meet the next round of emissions standards required for 2010, Navistar on Wednesday, March 4, unveiled its 2010 MaxxForce DT Advanced EGR (exhaust gas recirculation) midrange diesel engine at the National Truck Equipment Association (NTEA) Work Truck Show in Chicago.
“Our strategy of 2010 emissions compliance through the use of an EGR-only solution is on track,” said Steve Guillaume, Navistar general manager of vocational trucks. “With our lineup of MaxxForce Advanced EGR engines, we’re delivering a simple and straightforward solution that places the burden of emissions compliance on the manufacturer, not the customer.”

To meet the U.S. Environmental Protection Agency 2010 emissions requirements for on-highway diesel engines, MaxxForce Advanced EGR engines will use advanced fuel injection, air management, electronic controls and proprietary combustion technology.
“We’ve been conducting rigorous testing and analysis in our engine labs and currently have 2010 prototype engines installed in medium- and heavy-duty test trucks,” said Ramin Younessi, group vice president of truck and engine product development. “These test vehicles are on the road in real-world conditions and will log millions of miles of real-world experience before the launch of these engines.”
Other major truck and engine manufacturers are choosing a 2010 emissions path through selective catalytic reduction (SCR), which requires the use of an additional operating fluid, called urea, as well as additional aftertreatment equipment. Navistar says that for SCR systems in the United States, EPA will mandate a series of driver compliance requirements, as well as a disabling system that can power down the engine automatically when urea levels run low.
