本文指出,由于电力牵引可以实现很高的牵引功率,因而适用于高速运输和要求有高的加速功率的市郊运输。由于经济方面的原因,在数十年内继续发展内燃牵引具有重大的意义;在那些适用内燃牵引的地区,由于内燃牵引的优点,可以带来特别大的效益。采用具有油耗优化的柴油机和交流电力传动的内燃机车,牵引总效率达到35%以上。这个效率值对于电力牵引而言,几乎是不可能达到的。本文指出,在未来各种运输方式的激烈竞争中,为铁路带来了新的机遇。同时必须提高铁路的吸引力,如缩短运行时间、提高正点率和舒适性、提高环境可容性等。对未来内燃机车而言,应进一步提高牵引能力、经济性、可靠性、减少有害物质的排放等。同时对未来各种用途的内燃机车的发展趋势和技术要求作了概括介绍。
This paper points out that because electric traction can achieve high traction power, it is suitable for high-speed transportation and suburban transportation that requires high acceleration power. Due to economic reasons, it is of great significance to continue to develop internal combustion traction for decades. In areas where internal combustion is suitable for traction, the benefits of internal combustion can be of particular benefit. The use of diesel engine with optimized fuel consumption and AC power transmission diesel locomotive, the total traction efficiency of more than 35%. This efficiency value is almost impossible for electric traction. This article points out that in the future fierce competition of various modes of transportation, new opportunities have been brought to the railway. At the same time, the attractiveness of the railway must be enhanced, such as shortening the running time, improving the punctuality and comfort, and improving the environmental compatibility. For the future of diesel locomotives, should further improve traction, economy, reliability, reduce emissions of harmful substances. At the same time, the development trends and technical requirements of diesel locomotives for various uses in the future are summarized.
