Navistar to add Cummins SCR systems to its medium-duty MaxxForce engines next year

Navistar International Corp. has announced it will use SCR emissions-aftertreatment systems supplied by Cummins Emissions Solutions on its MaxxForce engines that power its International medium-duty trucks, starting in the first quarter of calendar year 2014.

The SCR announcement was included in the truck and engine maker’s release on its Q2 earnings. The company noted that it was “turning its focus” to adding SCR to its medium-duty products as its “heavy-duty launches [are] essentially completed.”

“We will introduce SCR in our medium-duty engines at the beginning of calendar year 2014, and we selected Cummins as our aftertreatment supplier,” said Navistar executive vp & COO Jack Allen yesterday, in a conference call with analysts on the earnings report. “For the past nine months, our engineering efforts have centered on adding SCR to our big bore engines. And now, this effort shifts to medium duty. And we're going to move as quickly as possible, but we won't compromise any of the quality gains we've made. And with this plan, we expect to avoid NCPs [Non-Conformance Penalties]on medium-duty engines, and it's likely we'll even have [emission-compliance] credits left over.”
