Eaton and Cummins Westport have launched an integrated powertrain package for the Cummins Westport ISX12 G natural gas engine – the first automated transmission to be paired with a spark-ignited natural gas engine in the North American market.
The powertrain combines an Eaton UltraShiftPLUS automated transmission with the Cummins Westport ISX12 G engine, and will be available for limited application release for linehaul and regional haul in mid-2014.
Speaking at a media event Sunday at the American Trucking Associations’ annual Technology & Maintenance Council meeting, executives said this product announcement is a continuation of the long-standing collaboration between Eaton and Cummins, and builds upon the announcement one year ago of the SmartAdvantage Powertrain package for the Cummins ISX15 diesel engine.
“We are proud to be able to offer North American fleet customers the first automated transmission to be integrated with a spark-ignited natural gas engine, which shows the level of customer commitment our teams are focused on providing,” says John Beering, Senior Vice President and General Manager, Commercial Vehicle Transmission Business, Eaton.
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; and tailored shift logic enables efficient operation and enhances braking performance
The Cummins Westport ISX12 G engine can be paired with either the UltraShift PLUS automated transmission or the Eaton Fuller Advantage Series manual transmission.
