Production Is to Commence in Mid-2016 at Cummins RMEP
Cummins Westport unveiled its latest engine, the all-natural gas, 6.7-liter, spark-ignition ISB6.7 G, at ACT Expo 2015 in Dallas evening.
Production is to commence in mid-2016 at EMEP, the Cummins Rocky Mount Engine Plant in Whitakers, N.C.
“It completes our product family,” says Cummins Westport president Rob Neitzke. The new engine complements Cummins Westport’s 8.9-liter ISL G and the 11.9-liter ISX12 G, and bringing the dedicated-natural gas option to a new class of vehicles.
Thomas Built School Buses First
The first application of the ISB6.7 G will be in Type C Thomas Built school buses, Neitzke told F&F, mentioning yard spotters and street sweepers as other potential markets. He notes too that the base Cummins ISB powers the popular Dodge Ram diesel pick-up truck.
Like the ISL G and ISX12 G, the new ISB6.7 G is a stoichiometric engine with cooled EGR/exhaust gas recirculation and three-way catalyst. Preliminary ISB6.7 G specifications include a range of ratings up to 260 horsepower and 660 foot-pounds torque.
The Cummins Westport joint venture was formed in 2001. “As of December 2014 we have delivered over 50,000 engines of which over 30,000 are ISL Gs,” says marketing director Jeff Campbell.
ACT Expo 2015 runs through May 7 at the Kay Bailey Hutchison Convention Center in Dallas.
