Kind of interesting, really. It seems that we're beginning to see two different modes of operation for Tier 4 final. Most manufacturers are jumping on the SCR boat, but some are using maximum EGR and minimum SCR to reduce DEF consumption while others are using maximum SCR and minimal EGR to reduce fuel consumption. Pick your poison!
