一种内燃机车燃油预热系统设计

Design of a fuel preheating system for diesel locomotive

在我国当前的铁路系统中,内燃机车占有相当大的比重,每年需要消耗大量的燃油。冬季尤其是在我国北方地区,内燃机车因采用高标号柴油要增加更多的成本,这就意味着在冬季若能采用低标号柴油将有很大的经济价值。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 railway traction system, the diesel locomotive occupies biggish proportion and consumes a large amount of fuel every year. In order to cut down the consumption of fuel oil, this paper discusses a heating system which can control the power of heating pipe for fuel tank according to the temperature of the fuel oil in the tank and the speed of diesel engine, so that it is possible to use lower grad of diesel oil in winter.
