Kenworth now offers the Cummins B6.7N natural gas engine for new Kenworth T180, T280, and T380 trucks designated for operation in the United States.

The Cummins B6.7N is a 100% natural gas engine featuring spark-ignited combustion with cooled EGR and a maintenance-free three-way catalyst. It features 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 (0.02 g/bhp-hr), which is 90% lower than the current EPA standard.

Rated up to 240 hp and 560 lb.-ft. of torque, the Cummins B6.7N may be used with either a compressed natural gas (CNG) or liquefied natural gas (LNG) fuel system.

The Kenworth T180 (Class 5), T280 (Class 6), and T380 (Class 7) possess versatility and maneuverability, spacious 2.1-meter wide cab, visibility, and driver-focused ergonomics. The Cummins B6.7N engine is available when these select medium-duty trucks are also specified with an aero hood and Allison automatic transmission.
