装有Serac2400调节器的法国国营铁路BB67620电传动内燃机车的运用经验证实:由于Serac 2400调节器能一直根据负荷情况使柴油机以尽可能低的转速运转,所以可降低发动机总的工作转数。自从1986年1月Serac 2400标准型电子调节器安装在法国国营铁路BB67620内燃机车上以来,已完成了10万km的运营。为了进行多种功能的试验,正在为另一台型号相同的机车装配这种喷油系统。业已清楚,与一般液压调速器相比,Serac电子调节器具有节约燃油、减少发动机磨损的能力,因为发动机在整个功率范围内均以非常接近其最高效率的转速运行。对这些节油情况
Experience with the SNCF BB67620 electric drive diesel locomotive with Serac 2400 turndown has proven that the total number of engine revolutions can be reduced since the Serac 2400 regulators always operate the diesel engine at the lowest possible speed depending on the load. Since January 1986, the Serac 2400 standard electronic regulator has been installed on the SNB BB67620 diesel locomotive and 100,000 km of operations have been completed. In order to test a variety of functions, another model of the same locomotive is equipped with this injection system. It is clear that Serac electronic governors have the potential to save fuel and reduce engine wear compared to a typical hydraulic governor because the engine runs very close to its maximum efficiency over the entire power range. For these fuel-saving situation
