本文简要叙述了为什么在高海拔地区运用的内燃机车需要进行功率修正,以及修正的原则和方法,还讨论了供油提前角对功率修正的影响;提出在海拔高差很大的特殊区段进行功率修正的方法及在成局峨段作了大量的试验研究。试验结果为机务段运用机车的调整提供了理论依据。 This article briefly describes why the diesel locomotives used in high altitude areas need to be corrected for power and the principles and methods of correction. The effect of fuel supply advance angle on power correction is also discussed. A special section with large elevation difference is proposed The method of power correction and a large number of experimental studies have been made on the Ertao section. The test results provide a theoretical basis for locomotive depot locomotive segment adjustment.
