Power management company Eaton and Cummins Westport, a joint-venture company of Cummins Inc. and Westport Innovations, have developed an integrated powertrain package for the Cummins Westport ISX12 G natural gas engine that will provide customers with the first automated transmission to be paired with a spark-ignited natural gas engine in the North American market. The powertrain will combine an Eaton UltraShift® PLUS automated transmission with the Cummins Westport ISX12 G engine.
Speaking at the American Trucking Associations’ annual Technology & Maintenance Council meeting, executives said that with the interest in alternative fuels driving more fleets to integrate natural gas engines into their portfolio, this product will meet a growing market need while providing best-in-class technology.
The Cummins Westport ISX12 G natural gas engine with heavy-duty durability is based on the Cummins ISX12 diesel engine, and operates on 100 percent natural gas, which can be carried on the vehicle in either compressed (CNG) or liquefied (LNG) form. Ideally suited for regional haul applications, the ISX12 G has a robust power band at 1500-1800 rpm with peak torque at 1200 rpm. This heavy-duty natural gas engine is available with horsepower of 320 hp to 400 hp (239-298 kW) with 1450 lb-ft (1966 N•m) peak torque.
The powertrain package benefits include:
Intelligent shift selection software for performance and efficiency improvements
Better launch and shift decisions through grade sensing, weight computation and driver throttle commands
Hill Start Aid, which prevents rollbacks when engaged, reduces risk and simplifies operations for even the most inexperienced drivers
Tailored shift logic enables efficient operation and enhances braking performance
The Cummins Westport ISX12 G engine can now be paired with either the UltraShift PLUS automated transmission or the Eaton Fuller Advantage Series manual transmission.
