Cummins Westport To Add 6.7 L To Natural Gas Lineup
Cummins Westport Inc. has announced that it has begun development on the ISB6.7 G, a mid-range 6.7 L natural gas engine. The company said the ISB6.7 G is designed to meet the increasing demand for on-highway vehicles powered by lower cost and cleaner fuels and the increasingly abundant availability of natural gas.
The ISB6.7 G engine will be based on the Cummins ISB6.7 diesel engine and will use Cummins Westport's proven spark-ignited, stoichiometric cooled exhaust gas recirculation (SEGR) technology. Exhaust aftertreatment will be provided by a maintenance-free three-way catalyst. The engine will operate on CNG, however, natural gas may be stored on the vehicle in an LNG state or as CNG.
The ISB6.7 G is expected to be in production by 2015 and will be designed to meet EPA and CARB regulations in force at the time of launch.
"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 L ISL G, with over 16,000 engines in service, and the 11.9 L ISX12 G, which will start production in 2013, to give our customers a broad range of natural gas engines for on-highway applications."
