1. Prevent engine from idling

即使是在空转，液压泵内还是会有油在循环并消耗燃料。假如1天10小时的作业时间中有1小时是在空转，那么，如果能防止空转，则每月可节省约20声、每年可节省约230升的燃料。所以，在日常装车或挖掘过程中，中途可以较长时间停机的时候，尽量不要开着挖掘机待速“等候”，要劳逸结合、更加省油，这是挖掘机省油诀窍之一

Even in idling, there will be oil circulating in the hydraulic pump and consuming fuel. If one hour of the 10 hour operation time in a day is idling, then if idling can be prevented, about 20 sounds per month and 230 liters of fuel per year can be saved. Therefore, in the daily loading or excavation process, when the excavator can be shut down for a long time, try not to "wait" while the excavator is running. It is necessary to combine work with rest and save more oil. This is one of the keys to save oil for the excavator

2、防止重载失压

2. Prevention of heavy load and voltage loss

当挖掘的沙土或石块负荷过重时，即使拉动操纵杆作业机械也无动作，而陷入失压状态。假如1天10小时的作业时间中有6分钟为失压状态，那么，如果能防止失压，则每月可节省约70升，每年可节省约840升柴油，这一笔费用将近5000元的费用。

When the digging sand or stone load is too heavy, even pulling the control lever, the machine will not move and fall into the state of pressure loss. If 6 minutes of the 10 hour operation time in a day is in the state of loss of pressure, if the loss of pressure can be prevented, about 70 liters of diesel can be saved every month, and about 840 liters of diesel can be saved every year, which costs nearly 5000 yuan.

3、降低发动机转速

3. Reduce the engine speed

虽然降低发动机转速会影响工作量，但却可以大幅减少燃耗，提升燃耗效率。当然，前提是不会致使干活效率太低，那样的话，可能引起雇主的反感而失去到手的工作。

Although reducing engine speed will affect the workload, it can significantly reduce fuel consumption and improve fuel consumption efficiency. Of course, the premise is not to make the work efficiency too low, in that case, it may cause the employer's disgust and lose the job.

4、减小回旋角度

4. Reduce the turning angle

减小在向自卸卡车装载时的回旋角度可以缩短作业周期，增加单位时间内的工作量，从而提升燃耗效率。这也是很有效的一种省油方法，很多机手在进行装车作业，很多时候往往想不到这点，因而多花了一部分冤枉的油钱。

Reducing the turning angle when loading the dump truck can shorten the operation cycle, increase the workload per unit time, and improve the fuel consumption efficiency. This is also a very effective way to save fuel. Many operators do not think of this when they are loading, so they spend more money on fuel.

5、行走时减少发动机转速

5. Reduce engine speed while walking

发动机转速越快，行走时所消耗的燃料就越多。通过减少运行时的发动机转速可以提升行走时的燃耗效率。

The faster the engine speed, the more fuel will be consumed when walking. The fuel consumption efficiency can be improved by reducing the engine speed.

6、实施高位挖掘

6. Implement high level mining

在挖掘现场，挖掘位置较高的部分而后再挖掘位置较低的部分的高位挖掘与低位挖掘相比，可以缩短约12%的周期用时并可提高约8%的燃耗效率。

In the excavation site, the higher part is excavated first, and then the lower part is excavated. Compared with the lower part, the high level excavation can shorten the cycle time by about 12% and improve the fuel consumption efficiency by about 8%.
