Truck/engine manufacturers receive EPA certification

The Diesel Technology Forum (DTF) has announced that all major heavy-duty truck and engine manufacturers have met new Environmental Protection Agency (EPA) standards for emissions cuts and have been certified by EPA for full production.

DTF said manufacturers now certified by the EPA include Caterpillar, Cummins, Detroit Diesel Corp, International, Mack, and Volvo.

The new big rigs are equipped with new particulate matter filters that trap emissions. Nitrogen oxide emissions also have been reduced.
