东风型内燃机车磁场削弱系数原设计为:β_1=53％,β_2=35％。这个数值是从全国不同线路条件出发考虑的,因而对于较平坦的线路,还有潜力可挖。我们通过在宁蚌区段牵引旅客列车的长期实践,证明在这种区段的牵引条件下,适当降低β值,就能提高列车技术速度,节约燃油消耗。下面介绍一下我们在这方 The original design of magnetic field weakening coefficient of DFM diesel locomotive is: β_1 = 53%, β_2 = 35%. This value is based on the national conditions of different lines to consider, so for the more flat lines, there is potential to dig. Through the long-term practice of towing passenger trains in the Ninglang section, we prove that by reducing the β value properly under the traction conditions in this section, we can improve the speed of train technology and save fuel consumption. Here is a brief introduction of us on this side
