为了适应铁路运输能力增长的需要,要求为提高效率作出决定性的努力。最近几年,在液力传动内燃机车的驱动装置的发展方面有了很大的进步。从研制和试验阶段的运行燃料费用要尽可能小来看,运行试验同费用远远超过它的试验台试验相比,前者具有越来越多的优点。 In order to meet the needs of the railway transport capacity growth, demands for decisive efforts to improve efficiency. In recent years, great progress has been made in the development of drive units for hydrostatic diesel locomotives. From the point of view of operating fuel costs during the development and testing stages to be as small as possible, the operational tests have more and more advantages over the cost of its test bench test.
