Fuel consumption of an extended arm excavator is a large daily cost.

　　一、防止发动机空转

　　I. Preventing Engine Rotation

　　即使在空转时，石油也会在泵中循环并消耗燃料。在日常装载或挖掘过程中，中途可以长时间停车，尽量不要驾驶挖掘机怠速“等待”，要把工作和休息结合起来，更加省油，这是挖掘机省油的窍门之一。

　　Even when idling, oil circulates in the pump and consumes fuel. In the process of daily loading or excavation, it is one of the tips for excavators to save oil by stopping for a long time in the middle of the road, avoiding idling and "waiting" while driving the excavator, and combining work with rest.

　　二是防止重负荷压力损失

　　The second is to prevent heavy load pressure loss

　　当开挖的砂石荷载过大时，甚拉动操纵杆操作的机械也没有动作，而陷入失压状态。“一口口不能吃大胖子”这个道理大家都很清楚，一把铲子不了问题，可以分成两部分来，否则既消耗机器成本，又消耗石油，损益相抵。

　　When the load of excavated sand and gravel is too large, even the machine that pulls the control rod to operate does not move, and falls into the state of losing pressure. We all know that a shovel can't solve the problem. It can be divided into two parts to solve it. Otherwise, it will not only consume machine costs, but also oil, and the profits and losses will offset each other.

　　三、降低发动机转速

　　3. Reducing Engine Speed

　　虽然降低发动机转速会影响工作量，但可以显著降低燃耗，提高燃耗效率。当然，如果这不会导致效率低下，就会让雇主望而却步，让他们丢掉工作。

　　Although reducing the engine speed will affect the workload, it can significantly reduce the fuel consumption and improve the fuel efficiency. Of course, if this does not lead to inefficiency, employers will be deterred from losing their jobs.

　　第四，减小旋转角度

　　Fourth, reduce the rotation angle

　　降低自卸车装载时的转角，可以缩短作业周期，增加单位时间的作业量，从而提高油耗效率。这也是有效的一种节油方法，很多机工在进行载重汽车操作，往往不经常想到这一点，因而浪费了一部分的油钱。

　　Reducing the turning angle of dump truck during loading can shorten the operation cycle and increase the amount of work per unit time, thus improving the efficiency of fuel consumption. This is also the most effective way to save fuel, many mechanics in the operation of trucks, often do not often think of this, thus wasting a part of the fuel money.

　　行走时降低发动机转速

　　Reduce engine speed while walking

　　发动机转得越快，就需要更多的燃料来行走。在运行时降低发动机转速可以提高燃油效率。

　　The faster the engine turns, the more fuel it needs to walk. Reducing engine speed during operation can improve fuel efficiency.

　　六是开展高水平挖掘

　　Sixth, carry out high-level excavation

　　在开挖现场，先高后低的高开挖，比低开挖周期缩短12%左右，燃耗效率提高8%左右。

　　In the excavation site, the excavation period of high excavation is shorter by 12% than that of low excavation, and the fuel consumption efficiency is increased by 8%.
