VANCOUVER, B.C. -- Cummins Westport has announced it plans to offer a mid-range natural gas engine based on Cummins’ 6.7-litre ISB.
The engine will use Cummins Westport’s spark-ignited, stoichiometric cooled exhaust gas recirculation (SEGR) technology. Exhaust aftertreatment will be provided by a three-way catalyst.
The ISB6.7 G will run off compressed natural gas (CNG), but the fuel can be stored on the vehicle in either compressed or liquefied form, the company announced.
“The addition of the ISB6.7 G will round out our family of high performance natural gas engines,” said Jim Arthurs, president of Cummins Westport. “It joins the 8.9-liter ISL G, with over 16,000 engines in service, and the 11.9-litre ISX12 G, which will start production in 2013, to give our customers a broad range of natural gas engines for on-highway applications.”
The latest offering will enter production in 2015 and will be aimed at medium-duty and vocational truck markets.
