Near zero emissions from the Cummins 6.7...
The B6.7N natural gas engine is available with ratings from 200 to 240 hp and up to 560 lb-ft. of peak torque. The B6.7N is designed for truck, school bus, and shuttle bus. Like Cummins Westport’s L9N and ISX12N engines, the B6.7N features on-board diagnostics, an enhanced, maintenance-free three-way catalyst, a closed crankcase ventilation system, and an engine control module recently redesigned for improved durability.
