柴油机班后加注燃油,对延长其使用寿命,充分发挥功率非常有益。当温度降低时,空气中的水蒸气会凝结成水滴。拖拉机发动机工作一天后,油箱中的油快用完了,油箱内油面以上的空间增大,即空气量增多,加之机体温度较高,箱内空气中会含有大量水分。停车后,温度逐渐
After the diesel class refueling, to extend its useful life, give full play to power is very useful. When the temperature decreases, the water vapor in the air condenses into droplets. One day after the tractor engine work, the oil in the fuel tank is almost used up. The space above the oil surface in the fuel tank increases, that is, the air volume increases. In addition, the air temperature in the air tank is high, and the air in the air tank contains a lot of water. After parking, the temperature gradually
