(一)前言随着我国内燃机车牵引的不断发展,越来越多的内燃机车投入到铁路运输中去。在西南地区也广泛地采用了内燃牵引。西南地区气候炎热,夏季有不少地区(如四川与贵州交界处的赶水、广西与贵州交界处的金城江一带)气温时常超过40℃。再加上线路中长大坡道较多,给内燃机车的运用带来了许多不利因素。因而,试验研究内燃机车高温工况下的性能已提到议事日程上来。环境大气条件(包括温度、压力、湿度)对柴油机功率的影响,在国外已进行过很多研
(A) Preface As China’s continuous development of diesel locomotive traction, more and more diesel locomotives into the railway transport. In the southwestern region also widely used in internal combustion traction. The climate in the southwest is hot with many areas in summer (such as catch-up at the junction of Sichuan and Guizhou and the Jincheng River at the junction of Guangxi and Guizhou) temperatures often exceed 40 ° C. Coupled with the ramp up in the line more, to the use of diesel locomotive brought many unfavorable factors. Therefore, the experimental study of the performance of diesel locomotives at high temperatures has been mentioned on the agenda. Environmental atmospheric conditions (including temperature, pressure, humidity) on the power of diesel engine in Japan has been a lot of research
