Nat-Gas Engine Unveiled as Some Wonder About Its Future

VANCOUVER, B.C -- Cummins Westport Inc. is broadening its offerings in natural gas engines for commercial vehicles as some are wondering what the future holds for this alternative fuel in the wake of lower diesel prices. The ISB6.7 G model is a 6.7 liter medium-duty, factory built, dedicated engine for medium duty truck and vocational applications as well as for school bus and shuttle bus applications. It's based on Cummins ISB6.7 diesel engine platform. This new model will operate exclusively on compressed natural gas (CNG) or liquefied natural gas (LNG), using Cummins Westport's proprietary spark-ignited, stoichiometric combustion with cooled exhaust gas recirculation (SEGR) technology, first introduced with the 8.9 liter ISL G model engine. The ISB6.7 G features three-way catalyst aftertreatment, which is packaged as a muffler and is maintenance-free. No diesel particulate filter or selective catalytic reduction after-treatment will be required, according to the company.
