美国蒙大拿铁路公司（MontanaRailLinkInc.）向FPC技术有限公司订购了一种FPC催化剂（Catalyst）装置，以用来处理它的燃油系统。在订货之前，曾先在该铁路的4台SD9型内燃机车上进行了一碳质量平衡试验。试验结果表明，该催化剂装置不仅使机车燃油消耗量平均降低了7．7％，而且 Montana RailLink Inc. ordered an FPC Catalyst device from FPC Technologies to process its fuel system. Prior to ordering, a carbon mass balance test was conducted on four SD9 diesel locomotives on the railway. The test results show that the catalyst device not only reduces the average fuel consumption of the locomotive by 7.7%, but also
