Rather than eliminate nitrogen oxide via a bulky chemical treatment system that even the EPA questioned initially, EGR would make the motor do all the work by piping exhaust gas back into the cylinders and burning it again a cleaner, cheaper, lower-maintenance solution, which would set Navistar ahead of the pack.
