柴油发动机冷启动困难分析与辅助循环加热装置的应用

Analysis of difficulty in cold start of diesel engine and application of auxiliary heating and circulating heat device

柴油发动机在高寒、高海拔地区时常会发生冷启动困难问题,通过分析柴油发动机冷启动困难原因,采用热循环原理及自动控制技术制作出了冷启动辅助循环加热装置,该装置通过提高发动机缸体温度能够很好的解决高寒、高海拔地区柴油发动机启动困难问题。

Diesel engine is often difficult to start in cold and high altitude areas.By analyzing the causes of difficult cold start of diesel engine,the auxiliary cycle heating device of cold start is made by using the principle of thermal cycle and automatic control technology.The device can solve the problem of difficult start of diesel engine in high altitude and cold regions by increasing the temperature of engine cylinder block.
