近几年,某些机务段对东风型机车操纵方法进行了“低手柄大功率”的尝试。所谓“低手柄大功率”,实际上是对现有的柴油机牵引特性作重新调整,使其更接近油耗的最佳经济线,用较低的手把位发出较大的功率,但一般不超过额定功率。在我们段,使用这种工况的机车手把常在13～15位,主发电机功率为1050千瓦。通过近 In recent years, some locomotive depots have made “low handle high power” attempts on the operation method of Dongfeng locomotives. The so-called “low power handle” is actually the best diesel engine to readjust the trait to make it closer to the best fuel economy, with a lower hand position to send a larger power, but generally not more than rated power. In our section, locomotives using this type of working conditions are usually located at 13 to 15 positions and the main generator has a power of 1,050 kW. Through
