Kenworth medium-duty trucks powered by natural gas
Kenworth now offers the Cummins B6.7N natural gas engine for new Kenworth T180, T280 and T380 trucks designated for operation in the U.S. The Cummins natural gas engine features spark-ignited combustion with cooled EGR and a maintenance-free three-way catalyst. It has a closed crankcase ventilation system and on-board diagnostics for optimal emissions performance. The near zero-emissions engine is certified to the California Air Resources Board’s optional low NOx standard, which is 90% lower than the current U.S. Environmental Protection Agency standard. Rated up to 240 hp and 560 ft-lbs of torque, the engine may be used with either a compressed natural gas or liquefied natural gas fuel system. 425-828-5551; www.kenworth.com
