拖拉机在夏季作业时,柴油机经常会发生温度过高的现象。此时,柴油机会因热膨胀而导致气缸充气量不足、功率下降;柴油机温度过高还会导致机油、润滑性能降低甚至运动机件卡死。因此,在夏季对柴油机冷却系的保养工作非常重要。 (1)检查水箱水位。柴油机启动前应检查水箱水位。闭式冷却系水箱的水位应高出散热器芯管口,且不得低于溢
When the tractor is working in summer, the diesel engine often has the phenomenon of overheating. At this point, the diesel engine due to thermal expansion caused by lack of cylinder inflated, the power down; Diesel engine temperature can lead to excessive oil, lubricating performance and even moving parts stuck. Therefore, in the summer of diesel engine cooling system maintenance work is very important. (1) Check the tank water level. Diesel engine should be checked before starting the water level. Closed water cooling tank water level should be higher than the core of the radiator nozzle, and shall not be less than overflow
