Truck and engine manufacturer Navistar Inc. said Thursday it has received its first Environmental Protection Agency certification for one of its 2010 engines and expects certification for the rest in the coming “days and weeks.”
Navistar received EPA certification for its MaxxForce DT mid-range diesel engines, spokesman Roy Wiley told Transport Topics.
The DT powers the medium-duty International DuraStar and severe-service WorkStar, as well as several models of Navistar’s IC Bus brand of school buses, the company said.
Navistar, which builds International Trucks, is the only North American producer that has elected to use exhaust gas recirculation to meet EPA mandates to cut nitrogen oxide emissions.
All other truck and engine makers chose selective catalytic reduction, or SCR, which treats NOx in aftertreatment, rather than in the engine, as EGR does.
“This is our first 2010 engine to receive EPA certification,” Wiley said.
“We anticipate receiving additional EPA certifications for our other engine families in the days and weeks ahead as our manufacturing plants begin to ramp-up for full production of our 2010 lineup of trucks and buses,” Ramin Younessi, Navistar’s group vice president for product development and strategy, said in a statement.
