Kenworth Truck Co. has added a natural gas option to its T880 vocational truck. The factory-installed Cummins Westport ISX12 G 400-hp. engine can now be spec’d on the T880 in either day cab or 52-in. mid-roof sleeper configuration.

The engine provides 1,450 lbs.-ft. of torque and is available with manual, automatic and Eaton UltraShift Plus transmission options, including 10-speed LAS and 13-speed MHP series.

The Cummins Westport ISX12 G can run on either CNG (compressed natural gas) or LNG (liquefied natural gas) fuel systems. The engine uses a maintenance-free, three-way catalyst and does not require a diesel exhaust fluid (DEF) tank, diesel particulate filter (DPF) or selective catalytic reduction (SCR) technology. Kenworth works with such companies as Agility Fuel Systems, Trilogy Engineered Solutions, and McNeilus to provide natural gas tanks and fueling systems.

“Kenworth continually expands our product offerings to meet customer needs and requirements,” said Kurt Swihart, Kenworth marketing director. “The new, natural-gas powered Kenworth T880 especially appeals to vocational fleets and truck operators interested in the T880’s excellent durability, reliability and driver comfort combined with cost-efficient natural gas.”

The Kenworth T880 also includes an air-assisted hydraulic clutch, complex reflector headlamps, 5-piece Metton hood for easier and faster repairs, and lightweight, factory-installed lift axles. The T880 uses Kenworth's 2.1-meter wide, stamped aluminum cab, which is robotically assembled. The cab has 23 in. of room between the seats.
