提高柴油机低温起动性能的预热燃油管开发

Development of Preheating Fuel Pipe for Improving Diesel Engine Cold Start Performance

针对柴油在低温下流动性变差的问题,开发了一种可对燃油进行加热的油管,利用汽车蓄电池对柴油加热,使柴油温度上升,提高流动性。试验结果表明,使用该装置后,柴油机在低温环境下燃用高凝点柴油可以迅速起动。

For the worse fuel fluidity at low temperature, a fuel pipe that could heat fuel was developed. With the automotive battery, the fuel temperature increased and the fuel fluidity improved. The results show that diesel engine can be fast started with the device at low temperature.
