IC Bus models, which use Navistar’s medium-duty engines, are expected by early next year to use Cummins Selective Catalytic Reduction (SCR) after-treatment technology to meet stricter federal emissions regulations.
While no official announcement has been made on school bus SCR, company spokesman Steve Schrier confirmed Cummins as the SCR aftertreatment supplier for its medium-duty trucks. Navistar has been using Cummins SCR engines in its heavy-duty truck line, with the first being the ISX15 earlier this year for the ProStar, 9900 and PayStar series. Since April, Navistar has also been using its MaxxForce13 with SCR for the ProStar.
Schrier added that Navistar expects to complete its SCR offerings for its entire heavy-duty line by this fall.
The SCR after-treatment announcement came as Navistar also posted a net loss of $374 million, or a $4.65 diluted share, more than double the 2012 figure for the period. Navistar blamed the disappointing figures on lower volumes and higher pre-existing warranties that were primarily related to the company’s decision to embrace Exhaust Gas Recirculation technology to meet 2010 EPA emissions for diesel engines.
“We are not satisfied with our overall financial results this quarter, but we are pleased with the continued progress we made in a number of areas on our turnaround plan,” said Troy A. Clarke, Navistar president and chief executive officer, during a results call. “We still face some significant, yet solvable challenges, primarily in the areas of higher pre-existing warranty costs for our earlier EPA 2010 emissions level engines, as well as in rebuilding sales and restoring market share. However, we are already implementing the right leadership and business process changes to effectively address these priority issues.”
Last July, Navistar announced it would introduce its next-generation, clean-engine solution, which was first referred to as In-Cylinder Technology Plus (ICT+). The company has since dropped that name in favor of SCR to meet the 2010 EPA emissions regulations and to position the company to meet greenhouse gas (GHG) rules in advance of 2014 and 2017 requirements.
Editor’s Note: A previous version of this story incorrectly stated that Navistar would use Cummins medium-duty engines. It should have said Navistar would use the Cummins SCR aftertreatment system for its medium-duty engines.
