Navistar has turned from advanced EGR to selective catalytic reduction (SCR), introducing its new engine strategy, a combination of in-cylinder technology and urea-based aftertreatment. Although no further details were announced, the company said both the EPA and California Air resource Board (CARB) "are encouraged by our plans," according to president and CEO Daniel C. Ustian.
Navistar has dubbed its technology In-Cylinder Technology Plus (ICT+) and said it will meet 2010 emissions regulations and will be available in early 2013. In the meantime, the company says, it intends to continue to build and ship current model EPA-compliant trucks in all vehicle classes using appropriate combinations of earned emissions credits and/or non-compliance penalties (NCPs) during the transition to ICT+.
Ustian also said that ICT+ will provide "a clear path to quickly achieving 2017 greenhouse gas standards."
The announcement comes on the heels of a federal court negating an agreement Navistar had reached with the EPA that allowed the company to pay a fine for each noncompliant engine it sold.
