1.起动困难 柴油机不易着火,首先要检查气缸压力是否充足。因为,柴油机是压燃,即利用本身压缩热点火,如果气缸压力不足,会使压缩温度降低,当压缩温度低于柴油自燃温度(350℃)时,喷入气缸的燃油就难以发火燃烧。造成气缸压力不足的原因有:缸壁、活塞、活塞环
1 start difficult diesel engine is not easy to fire, we must first check whether the cylinder pressure is sufficient. Because the diesel engine is a compression ignition, that is, the use of its own compression hot ignition, if the cylinder pressure is insufficient, will make the compression temperature decreases, when the compression temperature is lower than the auto-ignition temperature of diesel (350 ℃), the fuel injected into the cylinder is difficult to ignite the combustion. The reasons for the lack of cylinder pressure are: cylinder wall, piston, piston ring
