Douglas said environmental stewardship, which can be an important factor for truck operators in attracting new business, provides another reason why the ISX12 G promises to be a popular choice. The engine will allow truck operators to meet current and future environmental regulations more easily. When the ISX12 G is launched next year, Cummins Westport expects it to be certified to meet the U.S. Environmental Protection Agency and California Air Resources Board emission standards of 0.20 g/bhp-hr NOx and 0.01 g/bhp-hr PM. The engine is expected to be capable of meeting EURO VI and pending U.S. greenhouse gas and fuel economy regulations, he added.
