Navistar sources say it’s a “pretty good bet” that they’ll continue to use EGR on the medium duty products through 2013. Due to the failure to meet EPA standards Navistar is now offering SCR Cummins engines in their heavy duty trucks and will also switch to the SCR platform in their own heavy duty engines.
Navistar has enough credits to continue running the EGR engines until 2014 in the medium duty trucks. Their plan is to transition to SCR over time.
