Cummins said that its 6.7L Turbo Diesel has been certified by the California Air Resources Board (CARB) as meeting Low-Emission Vehicle III (LEV III) standards. This new standard applies to all vehicles under 14,000 lb. GVWR.
The Cummins 6.7L Turbo Diesel powers theHeavy-Duty lineup, and is the first medium-duty diesel engine in the 8,501-14,000 lb. GVWR segment to be certified to the new 2015 LEV III standards, Cummins said.
“At Cummins, we demand that everything we do leads to a cleaner, healthier and safer environment," said Jeff Caldwell, general manager - pickup business. "Being the first in this segment to certify to these new standards demonstrates our continued commitment to the environment, and meeting more stringent requirements without hardware changes allows us to maintain the proven capability and reliability that our customers have grown to expect."
Under LEV III, the nitrogen oxide (NOx) and non-methane organic gas (NMOG) standards are combined into a single NOx+NMOG standard, along with extension of emissions-useful life to 150,000 mi. 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.
