Excavator fuel consumption increased! How to solve it?

[BONOVO]

1. The fuel consumption of the excavator increases abnormally, and the fuel consumption increases;

2. Blue-black smoke from the lower exhaust;

Reasons for excavator burning oil

1. The lower exhaust of the excavator emits blue-black smoke during operation, and the oil consumption is also higher than usual, indicating that the excavator burns oil, which may be caused by piston ring wear, large valve clearance, large valve guide clearance, piston installation error, etc.

2. The clearance between the cylinder liner and the piston is too large, or the piston oil ring is stuck or cracked.

3. If the phenomenon of burning oil occurs with the phenomenon of lower exhaust oil dripping, it is likely that the piston ring is severely worn or cracked.

4. Burning oil, if the lower exhaust is not very serious, it may be caused by the lax sealing of the turbocharger. At this time, it is recommended to remove the pipes at both ends of the turbocharger to see if there is oil. If there is oil, it means that the turbocharger is faulty.

5. In addition, poor sealing of the engine valve oil seal will also cause the phenomenon of excavator burning oil.

6. Too much oil.

Common treatment methods for excavator oil burning

1. Check whether the oil is too much.

2. Check the turbocharger and loosen the hoses at both ends of the intake and exhaust. Normally, it should be dry. If there is oil, there may be a problem with the turbine, causing the oil to flow from the turbine to the exhaust pipe.

3. Pay attention to the exhaust pipe when you just start the engine in the morning. If there is thick black smoke and a clear smell of oil, it may be that the turbine is leaking oil.

4. Check whether the exhaust gas from the engine exhaust pipe is heavy. Normally, you should see light smoke at most. If the exhaust gas is very heavy, or even dripping oil in severe cases, it is time to repair the engine.

5. In addition, the turbo oil is usually not severe because the oil is not enough, so you should focus on checking the exhaust pipe.
