1. Prevent the engine from idling.

甚在空转时，液压泵内仍会有油在循环中消耗燃料。假设1天10小时的工作时间中有1小时是空转的，那么，如果可以防止空转，每月可以节省20声左右，每年可以节省230升左右的燃料。因此，在日常装车或挖掘过程中，中途可长时间停机时，尽量不要开着挖掘机待速等待，要劳逸结合，更省油，这是挖掘机省油的一个诀窍。

Even in idling, there will still be oil in the hydraulic pump to consume fuel in the cycle. Assuming that one hour of 10 hours of working time in a day is idling, if idling can be prevented, about 20 sounds can be saved every month, and about 230 liters of fuel can be saved every year. Therefore, in the daily loading or excavation process, when the excavator can be stopped for a long time in the middle, try not to drive the excavator to wait for speed, but combine work with rest to save fuel, which is a key to save fuel.

2.防止重载和压力损失。

2. Prevent heavy load and pressure loss.

当挖出的沙子或石头负荷过重时，即使拉动操纵杆，操作机械也不动作，陷入压力损失状态。如果10小时的工作时间中有6分钟处于压力损失状态，如果能防止压力损失，每月可节约70升左右，每年可节约840升左右的柴油，费用接近5000元。

When the excavated sand or stone is overloaded, even if the control lever is pulled, the operating machinery will not move and fall into the state of pressure loss. If 6 minutes of 10 hours of working time in a day are in the state of pressure loss, if the pressure loss can be prevented, about 70 liters of diesel can be saved every month, and about 840 liters of diesel can be saved every year, and the cost is close to 5000 yuan.

3.降低引擎的转速；

3. Reduce the engine speed;

尽管降低发动机转速会影响工作量，但可以大大降低燃烧消耗，提高燃烧效率。当然，前提是工作效率不会太低，可能会引起雇主的反感，失去工作。

Although reducing the engine speed will affect the workload, it can greatly reduce the combustion consumption and improve the combustion efficiency. Of course, the premise is that the work efficiency will not be too low, which may cause the employer's disgust and lose his job.

4.减小旋转角度。

4. Reduce the rotation angle.

减少装载自卸卡车时的旋转角度可以缩短工作周期，增加单位时间内的工作量，从而提高燃烧效率。这也是很有效的省油方法。许多机器人在装载作业时经常没有想到这一点，所以他们花了更多的油钱。

Reducing the rotation angle of loading dump truck can shorten the working cycle, increase the workload per unit time, and improve the combustion efficiency. This is also a very effective way to save fuel. Many robots often don't think of this when loading, so they spend more money on fuel.

5.行走时降低发动机转速。

5. Reduce the engine speed when walking.

发动机转速越快，行走时消耗的燃料越多。降低运转时发动机的转速可以提高行走时的消耗效率。

The faster the engine speed is, the more fuel will be consumed when walking. Reducing the engine speed can improve the consumption efficiency of walking.

6.是实施高位挖掘。

6. Implement high level mining.

在挖掘现场，挖掘高位部分，然后挖掘低位部分。与低位挖掘相比，高位挖掘可以缩短约12%的周期，提高约8%的燃烧效率。

In the excavation site, first excavate the high part, and then excavate the low part. Compared with the low-level excavation, the high-level excavation can shorten the cycle by about 12% and improve the combustion efficiency by about 8%.
