论述了内燃机车用Д100型柴油机空转工况时的各缸供油不均匀度的问题，及其所造成的后果，如机油稀释、后燃、燃油消耗量大等。较详细地介绍了一种改进喷嘴结构的措施，即在喷口端头通道中安装一圆柱型带对称平行侧隙的嵌块，以减少油道的容积。对上述结构改进。完成了大量的试验研究工作，对嵌块的几何尺寸进行了多方案的试验，选出最佳方案，并列出与原批量生产方案的对比效果，给出其推广使用的经济效益。
Discusses the problem of non-uniformity of oil supply of each cylinder in Д100 diesel engine with idling condition for diesel locomotive, and its consequences, such as oil dilution, afterburning, fuel consumption and so on. A more detailed description of a nozzle structure measures to improve the nozzle end of the channel to install a cylinder with symmetrical parallel backlash block to reduce the volume of the oil channel. Improve the above structure. Completed a large number of experimental research work on the geometric dimensions of the block a multi-program test, select the best program, and lists the original batch production program of the contrast effect, given its promotion of the use of economic benefits.
