Navistar Inc. announced Thursday, March 18, it has received certification from the U.S. Environmental Protection Agency for its 2010 MaxxForce DT Advanced EGR (exhaust gas recirculation) midrange diesel engines. The MaxxForce DT powers vehicles in many segments, from the medium-duty International DuraStar and severe-service International WorkStar, to several models of IC Bus brand school buses.
“Receiving EPA certification is an important milestone and marks one of our last stages prior to the launch of our 2010 trucks and engines,” says Ramin Younessi, group vice president of product development and strategy for Warrenville, Ill.-based Navistar. “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.”
International brand on-highway commercial vehicles and IC Bus brand school and commercial buses powered by 2010 MaxxForce engines will use MaxxForce Advanced EGR emissions technology, which doesn’t require urea as do systems based on selective catalytic reduction. Navistar says it has pursued its in-cylinder emissions solution path for most of the past decade to provide a customer-friendly powertrain in terms of fuel economy, performance and overall ownership costs.
