FOR THE RECORD
Navistar has submitted its MaxxForce 13 diesel engine to the U.S. Environmental Protection Agency for compliance testing, the company told attendees at a stock analyst meeting Feb. 1.
Last week, the California Air Resources Board issued a public letter to Navistar saying the company’s emissions credits for the MaxxForce 13 would expire Feb. 29.
Most diesel engine manufacturers chose to use selective catalytic reduction aftertreatment technology to meet the required emissions levels. Navistar diesel engines use an in-cylinder exhaust gas recirculation technology to reduce exhaust emissions and the company is the only North American engine manufacturer to do so.
A Navistar executive said the engine submitted to EPA has been “refined with an air management system and electronic engine controls.”
Currently, Navistar diesel engines emit more grams of nitrogen oxide than their competitors’ engines. But because Navistar exceeded the performance parameters set for earlier emissions reduction regulations, the company was awarded emissions credits by the EPA that allow them to do so.
“The bottom line is that Navistar will sell engines in 2012 that are fully certified in all 50 states,” said Jack Allen, president of Navistar’s Engine Group, during the analysts meeting in Chicago. “And any issue between Navistar and the EPA will remain between us and the EPA and will not affect Navistar customers.”
