Cummins announced that it has received certification for its 6.7L Turbo Diesel from the California Air Resources Board, meeting the Low-Emission Vehicle III standards.
This new LEV III standard applies to all vehicles under 14,000 pounds GVWR.
The Cummins 6.7L Turbo Diesel powers the Ram Heavy-Duty lineup, and is the first medium-duty diesel engine in the 8,501-14,000-pound GVWR segment to be certified to the new 2015 LEV III standards, according to Cummins.
Cummins was able to meet the more stringent requirements without hardware changes, according to Jeff Caldwell, General Manager - Pickup Business.
Under LEV III, the nitrogen oxide and non-methane organic gas standards are combined into a single NOx+NMOG standard, along with extension of emissions-useful life to 150,000 miles for emissions control systems. LEV III standards also introduce more stringent NOx+NMOG fleet average requirements, which phase in from MY 2015-2022 for all medium-duty vehicles. These new standards were adopted by CARB in January 2012.
Cummins began providing diesel engines to Chrysler in 1988, and has shipped over 2 million engines in the last 25 years.
