功率可自动调节的内燃机车燃油预热系统设计

Design of Power Self-adjusting Fuel Preheater System of Diesel Locomotive

在我国当前的铁路系统中,内燃机车占有相当的比重。尤其是在我国北方地区的冬季,内燃机车因采用高标号柴油要增加更多的成本。从各标号柴油的物理参数看,只是冷凝点不同,其它参数都一致,但价格差别很大,而且不同标号的柴油在油耗实验中的平均油耗基本相同,这就意味着在冬季机车若能使用低标号柴油将具有很大的经济价值。就此提出了一套构造简单,且可随燃油箱供油的温度及柴油机转速自动调节加热管功率的加热系统。

In our country＇s present railway system,the diesel locomotive occupies biggish proportion,especially in the northern area of our country,which increase more cost because of using high-grade diesel oil in winter.By the look of physical parameters of every grade diesel oil,only condensation points are different,other parameters are identical,but the price differs significantly,and the average oil consumption of different grade diesel oil is basically the same in the oil consumption experiment,this means that using the diesel oil of low grade has very great economic worth in winter.This text has proposed a set of simple structure,it can change the power of heating pipe automatically as the temperature of the oil and the rotational speed of diesel engine change.
