The excavator burning engine oil is very harmful to the excavator itself. Failure to solve the problem of burning engine oil will become a hidden danger of the excavator and shorten the service life of the machine. Now let's share the cause and troubleshooting of the excavator burning oil!
Reasons for oil burning of excavator:
1. The excavator oil pump is faulty. It is necessary to calibrate the diesel oil pump ① supercharger fault ② oil nozzle is worn or does not match ③ the engine valve clearance is too large, which may also cause the excavator to burn oil ④ the oil pump governor is worn ⑤ the combustion is not good, and the atomization is poor ⑥ the oil supply time is not correct ⑦ the compression ratio is not correct, which may also cause the excavator to burn oil ⑧ insufficient air intake
2 The piston rings are aligned. ① The clearance between the piston and the cylinder wall is too large ② The filter is blocked, which may cause the excavator to burn oil ③ The clearance between the cylinder liner piston is too large ④ The ignition time of the engine is incorrect ⑤ The fuel injection nozzle is worn or the model of the fuel injection nozzle does not match, which may also cause the excavator to burn oil ⑥ The diesel pump needs to be calibrated
3 The air filter of the excavator is too dirty. ① The oil used by the excavator is incorrect, or the quality of the oil used is too poor, which does not match the excavator model. ② The excavator engine blows air. ③ The turbocharger oil seal in the excavator is damaged. ④ The engine has a problem, causing the excavator to burn oil. ⑤ The piston ring is aligned. ⑥ The excavator has a problem with the four matching parts. It needs to be replaced. ⑦ The air inlet is insufficient. ⑧ The oil pump governor is worn.
Common disposal methods for excavator burning oil:
1. Check whether there is too much oil.
2. Check the turbocharged turbine and loosen the rubber hoses at both ends of the intake and exhaust. It should be dry normally. If oil is found, it may be that there is something wrong with the turbine, causing the oil to flow from the turbine to the exhaust pipe.
3. Pay attention to the exhaust pipe when you start burning in the morning. If there is thick black smoke and clear oil smell, it indicates that the turbine is leaking oil.
4. Check whether the exhaust gas in the engine exhaust pipe is heavy. Normally, you should see light smoke at most. If the exhaust gas is heavy, severe or even drips oil, it is time to repair the engine.
5. In addition, turbine oil channeling is usually not fierce, so check the exhaust pipe.
