Liugong excavator parts tell you how much damage the intake and exhaust system causes to the engine

2025-04-21

The intake and exhaust system of Liugong excavator accessories is similar to our human respiratory system, completing many complex steps between breathing and inhaling. However, in many steps, fresh air is needed to participate in combustion to ensure the power output of the engine. So how much impact does the intake and exhaust system have on excavators?

I. What is the intake and exhaust system?

The intake and exhaust system continuously sends fresh air or combustible mixture into the combustion chamber during the operation cycle of the internal combustion engine, and then discharges the incinerated exhaust gas into the atmosphere.

1. The function of the intercooler in Liugong excavator accessories is to lower the temperature of the pressurized gas to improve inflation efficiency and increase intake volume.

2. The function of an air filter is to remove dust and sand particles from the air, in order to reduce wear on the cylinder, piston, and piston rings.

3. The exhaust gas turbocharger of Liugong excavator accessories uses the burned exhaust gas to drive the turbine to roll, thereby driving the compressor impeller installed coaxially with it to operate. The impeller rolling presses more fresh air into the cylinder.

4. The intake volume is the main factor determining engine power!! !

5. The cleanliness of the intake is an important factor affecting the lifespan of the engine!!!!

II. Symptoms and maintenance methods of intake and exhaust system problems

1. Liugong excavator parts turbocharger compressor front pipeline leakage:

2. Dust and other foreign objects enter the engine, causing rapid wear of the cylinder;

3. The compressor blades are damaged and the turbocharger is damaged.

4. Turbocharger compressor front pipeline blockage

5. Smooth engine oil that easily forms a turbocharger enters the cylinder through the compressor end and burns, causing the vehicle to burn engine oil.

6. Liugong excavator parts turbocharger compressor rear pipeline leakage:

7. Lack of intake/power

8. Dust may also be inhaled at idle or low load speeds!

9. Liugong excavator parts turbocharger compressor rear pipeline blockage:

10. Lack of intake/power

11. Turbocharger - Exhaust gas turbine front pipeline leakage:

12. Lack of exhaust gas, resulting in a lack of intake air and a lack of power.

13. Turbocharger - Exhaust gas turbine rear pipeline blockage:

14. Poor exhaust emissions result in a lack of intake and power.

Note: Lack of sealing in the turbocharger air filter, cracked bolt holes in the intake pipe, inadequate sealing in the intake pipe, defective air filter, and lack of maintenance can all lead to wear and tear on the turbocharger, piston rings, piston strains, cylinder liner strains, and other parts of the LiuGong excavator.

III. Maintenance methods

Air intake system

1. Check whether there is dust on the inner wall of the pipeline. If there is dust, immediately find the entry and exit points and handle them;

2. Check if the installation bolts of the pipeline are loose or cracked. If they are loose, tighten them immediately. If they are cracked, replace the faulty parts;

3. Check if there is any looseness or air leakage in the intake pipe after the turbocharger of the LiuGong excavator parts, and tighten it if necessary;

4. Check the clamps of the entire system, it is necessary to tighten them in place;

air filter

1. Regularly check and tidy up the dust, dirt, etc. inside the shell, pay attention to whether the shell is damaged, and replace it if it is damaged;

2. Check if the air filter outlet pipe of the Liugong excavator accessory is tightened properly, and replace it if necessary;

3. The main filter element is only allowed to be sorted 5 times, and it is necessary to replace it after 5 times. If it is damaged, it is also necessary to replace it;

4. The safety filter element can only be replaced and cannot be sorted;

5. Pay attention to the connections of dust valves and other components;

air filter

After loosening the locking handle, remove the filter housing.

2. After releasing the second locking handle, remove the external filter element; During this operation, special care should be taken to ensure that no dust enters the liner.

3. Check if there is no dust or dirt. If applicable, clean the filter element according to the following method.

4. Blow dehumidified compressed air (maximum pressure: 200 kPa) from the inside out of the filter element of the LiuGong excavator accessory. Do not use cleaning agents; Do not use diesel fuel.

5. Do not use objects to hit the filter element; Check its condition before replacing.

If cracks or damages are found, the filter should be replaced.

7. Check if the sealing gasket of the bottom Liugong excavator accessory is in good condition. Some filter systems are installed with secondary filter elements that do not require cleaning; The main filter element must be replaced every 3 times.

When reinstalling, repeat the above operations in reverse order.
