Suit Alleges EGR-Only System Caused Excessive DowntimeWhen EPA regulations started going into effect for Class 8 trucks requiring lower emissions levels and, specifically, lower NOx levels, the commercial trucking industry almost unanimously went in the direction of urea aftertreatment to meet the new federal standards, with one notable exception. Navistar, maker of International-brand trucks, aimed to meet the new regulations using just exhaust gas recirculation (EGR), claiming lower maintenance costs compared to urea selective catalyst reduction (SCR) systems. This week, Class 8 truck operators in three states are filing suit against Navistar for false product representations, as well as lost profits due to downtime for repairs on trucks equipped with MaxxForce engines with the EGR system.
