Cummins 6.7L Turbo Diesel first medium-duty engine certified to meet LEV III standards; Ram Heavy-Duty
Cummins Inc. has received certification for its 6.7L Turbo Diesel from the California Air Resources Board (CARB), meeting the 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 the Ram Heavy-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.
Under LEV III, 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 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 the Air Resources Board (ARB) in January 2012.
Cummins began providing diesel engines to Chrysler in 1988, and has shipped more than 2 million engines in the last 25 years.
