Fuel consumption of excavator is a major item of daily cost

　　，防止发动机空转

　　First, prevent the engine from idling

　　即使在空转时，液压泵内也有油循环，消耗燃料。每天装载或开挖过程中,当机器可以停止在中间很长一段时间,尽量不要把挖掘机闲置和“等待”,但把工作与休息,节省燃料,这是一个技巧的挖掘机,以节省燃料。

　　Even when idling, there is oil circulation in the hydraulic pump, which consumes fuel. In the process of loading or excavation every day, when the machine can be stopped for a long time in the middle, try not to leave the excavator idle and "wait", but work and rest to save fuel. This is a skilled excavator to save fuel.

　　第二，防止过载损失压力

　　Second, prevent overload loss of pressure

　　当开挖的砂土或岩石荷载过大时，即使拉动操作机械的杠杆也不起作用，并陷入压力损失的状态。“一口气不能吃大胖子”这个道理大家都清楚，一铲不了问题，可以分成两部分来，否则既费机子，又耗油，得不偿失。

　　When the excavation of sand or rock load is too large, even pulling the lever of operating machinery will not work, and fall into the state of pressure loss. We all know that a shovel can't solve the problem. It can be divided into two parts. Otherwise, it will cost both machine and fuel, and it won't pay off.

　　三、降低发动机转速

　　III. reduce engine speed

　　虽然降低发动机转速会影响到发动机的运行量，但是可以大大降低油耗，提高燃油效率。当然，如果这样做不会降低工作效率，就会让雇主失去兴趣，让他们失去工作。

　　Although reducing the engine speed will affect the engine operation, it can greatly reduce fuel consumption and improve fuel efficiency. Of course, if this does not reduce work efficiency, it will make employers lose interest and work.

　　四、减小旋转角度

　　IV. reduce the rotation angle

　　减少挖掘机的回转角度，可以缩短操作周期，增加单位时间的工作量，从而提高燃油消耗效率。这也是更有效的省油方式，很多移动运营商在装油操作的时候，很多时候往往没有想到这一点，从而花费了一部分错误的油钱。

　　Reducing the rotation angle of the excavator can shorten the operation period, increase the workload per unit time, and improve the fuel consumption efficiency. This is also the most effective way to save fuel. Many mobile operators often fail to think of this when they are loading oil, thus spending part of the wrong fuel money.

　　走路时降低引擎速度

　　Reduce engine speed when walking

　　发动机转速越快，在行走时消耗的燃料越多。燃油效率可以通过降低发动机运行速度来提高。

　　The faster the engine speed is, the more fuel will be consumed during walking. Fuel efficiency can be improved by reducing the engine speed.

　　实施高水平挖掘

　　Implement high level mining

　　在开挖现场，与低位置开挖相比，先高位置部位的高位置开挖与低位置部位的低位置开挖可缩短循环时间约12%，提高燃耗效率约8%。

　　In the excavation site, compared with the low position excavation, the high position excavation in the first high position and the low position excavation in the low position can shorten the cycle time by about 12% and improve the fuel consumption efficiency by about 8%.
