One step closer to meeting the stringent emissions standards required for 2010, Navistar on Tuesday, Feb. 3, unveiled its 2010 MaxxForce 13-liter Advanced EGR engine at the World of Concrete show in Las Vegas, Nev.
“Our strategy of 2010 emissions compliance through the use of an EGR-only solution is on track,” says Jim Hebe, senior vice president of North American sales operations for Warrenville, Ill.-based Navistar. “Through our lineup of MaxxForce Advanced EGR engines, we’re providing customers with 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 standards 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 more than 25 medium- and heavy-duty test trucks,” says Ramin Younessi, group vice president of truck and engine product development. “These test vehicles are on the road in real-world conditions, in fleets and in the hands of our customers. We will have logged millions of miles of real-world experience before the launch of these engines.”
Other major truck and engine manufacturers are choosing to meet 2010 emissions through selective catalytic reduction (SCR), which requires the use of an additional operating chemical, called urea, as well as additional aftertreatment equipment. And for SCR systems in the United States, EPA will require a series of driver compliance controls, including a complex array of warning lights as well as a disabling system that will power down the engine automatically when urea levels run low.
“We strongly believe the accountability for emissions compliance should rest on the manufacturer, not on the actions of the driver, the reliability of very complex technologies or the impact of climatic conditions,” Hebe says. “The development and testing of our EGR solution for 2010 is in advanced stages, and we are confident that our engines will deliver the performance, reliability and low operating costs our customers demand.”
