Navistar Looks to Cummins to Supply SCR; Offers ISX15

(Aug. 2, 2012) —  Navistar International says it will adopt Cummins’ selective catalytic reduction (SCR) engine technology to help it implement its In Cylinder Technology Plus (ICT+) emissions plan.

To accelerate delivery of ICT+, Navistar has entered into a non-binding memorandum of understanding, with  Cummins Emission Solutions, which will supply its proven urea-based aftertreatment system to Navistar.

Navistar expects that by combining Cummins’ aftertreatment system with its existing MaxxForce engines, its ICT+ will meet 2010 U.S. Environmental Protection Agency (EPA) emissions regulations and position the company to meet greenhouse gas (GHG) rules in advance of 2014 and 2017 requirements.

The company was previously using only its in-cylinder, advanced exhaust gas recirculation (EGR) solution, which fell short of meeting the 2010 EPA 0.2 gram- NOx limit. Last month, a U.S. Court threw out an EPA interim rule which allowed the company to sell the engines by paying a fine.

During the transition, Navistar says it will continue to build and ship current model EPA-compliant trucks in all vehicle classes using appropriate combinations of earned emissions credits and/or non-conformance penalties (NCPs).

The company also announced an agreement to offer the Cummins ISX15 engine in certain models beginning in January 2013. Its ICT+ solution will be offered in early 2013 on the MaxxForce 13.
