Navistar engines produced for several models of heavy-duty trucks are only certified to meet federal emissions standards until late February. After that point, the truck builder will have run out of emissions credits unless it unveils a new engine that meets federal NOx standards.
Navistar says it has a plan and will be unveiling a new engine “very soon.”
In a document certifying Navistar engines until Feb. 29, CARB said that based on Navistar’s statement of federal emissions credit balance and projected production of its diesel engines, its executive order certifying Navistar engine production “only covers engines produced on or before Feb. 29, 2012.
The emissions credits issue affects Navistar big bore engines of 11, 13 and 15-liters, said Navistar Spokeswoman Karen Denning.
“Navistar remains confident in our EGR strategy and will be submitting a .2 engine for certification very soon,” Denning told Land Line Magazine Monday.
EPA 2010 emissions standards require heavy-duty diesel engines to emit .2 grams of oxides of nitrogen per brake horsepower-hour.
The company will explain more at its Analyst and Investor Day next week, Denning said.
