1. Prevent the engine from idling

在怠速时液压泵中仍会有油在循环中消耗燃油，在日常装车或挖掘过程中，当机器在中途可以长时间停机时，尽量不要开挖掘机等待提速，而是劳逸结合节省燃油，这是挖掘机节省燃油方法。

At idle speed, there will still be oil in the hydraulic pump that consumes fuel in circulation. In the process of daily loading or excavation, when the machine can be stopped for a long time in the middle, try not to drive the excavator to wait for speed increase, but combine work and rest to save fuel. This is the way for the excavator to save fuel.

2.防止重载和压力损失

2. Prevent heavy load and pressure loss

当挖出的砂或石超载时即使拉动操纵杆，作业机械也不动，进入失压状态够防止压力损失。

When the excavated sand or stone is overloaded, even if the control lever is pulled, the operation machinery will not move and enter the pressure loss state, which is enough to prevent pressure loss.

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负荷，但可以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。

Although reducing the engine speed will affect the working load, it can reduce the combustion consumption and improve the combustion efficiency, of course, on the premise that the working efficiency will not be too low.

4.减小旋转角度。

4. Reduce the rotation angle.

装载挖机时减小旋转角度可以缩短工作周期，增加单位时间的工作量，从而提高燃烧效率，这也是非常有效的省油方式。

When loading the excavator, reducing the rotation angle can shorten the working cycle and increase the workload per unit time, so as to improve the combustion efficiency, which is also a very effective fuel-saving way.

5.行走时降低发动机转速

5. Reduce the engine speed when walking

挖机的发动机转速越快，行走时消耗的燃油越多，跑步时降低发动机转速可以提高行走时的消耗效率。

The faster the engine speed of the excavator is, the more fuel is consumed during walking. Reducing the engine speed during running can improve the consumption efficiency during walking.

6.实施高位开采

6. Implement high-level mining

在挖机现场先挖掘高的部分，然后挖掘低的部分，与低位开挖相比高位开挖可缩短周期约12%，提高燃烧效率约8%。

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