The Kenworth T680 on-highway flagship truck and T880 and T880S vocational trucks are now available for order with the Cummins Westport ISX12N near zero NOx emissions natural gas engine.
The ISX12N has been certified the California Air Resources Board’s optional low –NOx standard as of 0.02 g/bph-hr as well as the less-stringent current EPA NOx limit. The engine features a closed crankcase ventilation system, a three-way catalyst, on-board diagnostic capability, and a durable engine control module.
The 12-liter ISX12N equipped on the Kenworth T680, T880 and T880S offer ratings up to 400 horsepower and 1,450 lbs.-ft. of torque. The engine can operate on compressed natural gas and liquefied natural gas, as well as renewable natural gas, which offers additional reductions in GHG emissions. RNG is produced from the decomposition of organic waste from such sources as dairy farms, landfills, and urban waste treatment plants.
Earlier this month, Kenworth also announced the smaller 8.9-liter Cummins Westport L9N near zero NOx emissions natural gas engine as an option on the T680, T880 and T880S.
“The Cummins Westport ISX12N provides an excellent, very low-emissions solution for fleets and truck operators that order the Kenworth T680, T880 and T880S for service in line haul, regional haul, vocational and refuse applications,” said Kurt Swihart, Kenworth marketing director.
