EPA loses legal battle over Navistar’s EGR engine

The Environmental Protection Agency lost a legal battle over Navistar engines

The Environmental Protection Agency lost a legal battle last week when a federal appeals court agreed with several long-haul truck manufactures that the agency shouldn’t have let Navistar sell certain engines. Specifically, Fleetowner reports that the ruling says that the EPA should not have allowed the company to continue selling its MaxxForce advanced exhaust gas recirculation (EGR) diesel engines subject to non-conformance penalties (NCPs) even though they did not meet the agency’s standards for oxides of nitrogen (NOx).

The decision will unlikely effect Navistar because in 2012, the company made the move to switch the select catalytic reduction (SCR), and according to Fleetowner, it has completed the transition to SCR for all of its Class 8 products.
