| 摘 要： | 针对在极地气候对吊管机用柴油机进气道采用加热辅助冷起动技术，即采用压缩天然气（CNG）加热器燃烧加热空气，利用颗粒式热容器，实现对空滤器过来的冷空气加热的目的。加热后的空气通过进气歧管，进入气缸，实现整个进气管路的加热，使得柴油机起动时进入气缸的空气平均温度达到0℃以上，从而确保柴油机在-45℃条件下顺利起动。

| Abstract: | Against the polar climate, the intake manifold of the pipeplayer - driving diesel engine are heated by the CNC heater and the heat container . The heated air flows into cylinders through intake pipes to warm the intake pipes. When the diesel engine starts, air in the intake pipe increases to over 0℃, ensuring the diesel engine starting smoothly. |
