CARB Certifies Cummins’ 6.7-Liter

Cummins Inc. says the California Air Resources Board (CARB) has certified its 6.7-liter turbo diesel engine against the 2015 Low-Emission Vehicle III (LEV III) standards, which apply to all vehicles under 14,000 lbs. GVWR.

Under LEV III, 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 miles for emissions control systems. LEV III standards also introduce more stringent NOx+NMOG fleet average requirements, which phase in during model years 2015 to 2022 for all medium-duty vehicles.

Cummins' 6.7-liter diesel is the power plant for the Ram Heavy-Duty lineup. The company says the engine is the first in the medium-duty (8,501-14,000 lbs. GVWR) segment to be certified to the new LEV III standards.
