Ou Man 8 can't get on.

There may be many reasons why Ou Man can't keep up. Here are some possible reasons and solutions:

1. air filter blockage: air intake will be insufficient due to air filter blockage, resulting in insufficient power of diesel engine. The solution is to replace or clean the air filter.

2. Blockage of oil circuit: Blockage of oil circuit will lead to insufficient oil supply and insufficient power of diesel engine. The solution is to clean the oil circuit.

3. Poor atomization of fuel injector: Poor atomization of fuel injector will lead to insufficient fuel combustion and insufficient power of diesel engine. The solution is to adjust or replace the fuel injector.

4. Insufficient combustion: Insufficient combustion will reduce the efficiency of the diesel engine and lead to insufficient power. The solution is to adjust the combustion chamber structure or change the diesel engine model.

5. Engine lack of cylinder: Engine lack of cylinder will make diesel engine lack of power. The solution is to check the causes of engine cylinder loss and carry out maintenance.

6. Clutch slip: Clutch slip will make the engine output power insufficient, resulting in insufficient power. The solution is to adjust the clutch clearance and carry out maintenance.

7. Transmission system failure: Transmission system failure will prevent power from being transmitted to the wheels, resulting in insufficient power. The solution is to check the transmission system and carry out maintenance.

8. Sensor failure: Sensor failure will lead to engine control system failure, resulting in insufficient power. The solution is to check the sensor and repair it.

These are some possible reasons and solutions. It is recommended that you do not continue to use the vehicle until the problem is solved, so as not to cause greater failures and losses. I suggest you go to Ou Man Service Station for maintenance as soon as possible.
