1977年s月份全国推广优选法小分队来到我们段,在段党委领导下组成了三结合试验小组,对影响柴油机性能的供油系统主要部件的结构参数进行了调查研究和现车试验,简单介绍如下。(一)添乘调查试验小组对全段内燃机车耗油情况进行摸底,每台车万吨公里耗油都在29～36公斤之间。东风4 2031号机车节油较少,甚至费油,而东风4 2027号机车是中游机车。添乘过程发现2031号机车手柄放在13～14位,而2027号机车手柄放到11～12位都是正点运行,但耗油不一。除去客观影响因素外,还有机车本身性能上的差别,并发现两台车的废气支管及总管都变
In 1977, the National Optimization Law Team came to our country in July. Under the leadership of the Party Committee of the Party, a three-pronged test group was formed to investigate and test the structural parameters of the main components of the oil supply system that affect the performance of the diesel engine. as follows. (A) Tim Lim survey team conducted a thorough examination of the fuel consumption of diesel locomotives in the entire section. Fuel consumption per tonne of vehicles was between 29 and 36 kilograms. Dongfeng 4 2031 locomotive less fuel-efficient, or even oil, and Dongfeng 4 2027 locomotive is the middle reaches of locomotives. Tim process found 2031 locomotive handle on the 13 to 14, while the 2027 locomotive handle put 11 to 12 are punctual operation, but different fuel consumption. In addition to the objective factors, there are differences in the performance of the locomotive itself, and found that both the exhaust branch pipe and the Explorer have changed
