Navistar Gives Up on EGR-Only Diesel Emission Control

Navistar International Corp. says it will supplement its failed diesel emission control strategy with a urea aftertreatment system already used by its competitors.
The truckmaker had hoped to meet 2010 U.S. oxides of nitrogen emission standards by using only an relatively inexpensive exhaust gas recirculation system it developed with and licensed the technology from the Environmental Protection Agency. But Navistar's engines failed to achieve certification with the EGR system alone. The EPA has allowed the company to sell noncompliant 13-liter diesels in exchange for paying a fine as high as $1,900 per engine sold.
Navistar says it will continue to use the EGR system but supplement it with a urea-based selective catalytic reduction system that treats exhaust gas after it leaves the engine. The company tells analysts it already sells diesels in Brazil that use similar technology.
Navistar expects a urea-equipped version of its 13-liter diesel to debut in the U.S. early next year after completing EPA certification. The truckmaker also plans to add the technology to its 15-liter engine in 2013.
