Navistar unveiled its 2010 MaxxForce DT Advanced EGR mid-range diesel engine at the National Truck Equipment Association Work Truck Show in Chicago this week.


"Our strategy of 2010 emissions compliance through the use of an EGR-only solution is on track," said Steve Guillaume, Navistar general manager, vocational trucks. "With our line-up 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 proven technologies such as 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, 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."

Navistar says that unlike the Selective Catalytic Reduction approach to 2010 being used by other engine manufacturers, its EGR approach will not require the use of urea-based diesel exhaust fluid or the addition of on-vehicle urea storage tanks, converters, heaters, and the additional electronics required by SCR systems.
