The Kenworth T680 on-highway flagship and Kenworth T880 and T880S vocational trucks are now available with the Cummins Westport L9N near zero NOx emissions natural gas engine.
The L9N engine is certified to the California Air Resources Board’s optional low NOx standard for emissions, representing a 90% reduction from engines operating at the current Environmental Protection Agency NOx limit.
The L9N features on-board diagnostic capability, a three-way catalyst, closed crankcase ventilation system, and an engine control module designed for durability.
On the Kenworth Trucks, the 8.9-liter L9N is rated at 320 horsepower and 1,000 lbs.-ft. of torque. It can be powered by either compressed natural gas or liquefied natural gas and is also compatible with renewable natural gas, which offers a further reduction in greenhouse gas emissions.
“The Kenworth T680, T880, and T880S specified with the Cummins Westport L9N near zero emissions engine are ideal for pickup and delivery, vocational and refuse fleets focused on reducing their environmental impact and decreasing operating costs,” said Kurt Swihart, Kenworth marketing director.
