Reasons for the failure of blue smoke from excavator:
1. The blue smoke from the cool car may be because the fuel injection nozzle is stuck, or the diesel pump needs to be calibrated.
A. The valve oil seal is not well sealed.
B. There is a problem with the oil-water separator.
C. The piston ring is worn, causing the blue smoke failure of the excavator.
D. The grade of the selected oil is too high.
2. Blue smoke is still emitted after the excavator is started, indicating that the excavator oil may be burned, then the reasons for the failure are as follows:
A. The excavator turbocharger oil seal is worn.
B. There is a problem with the engine cylinder piston.
C, The gap between the valve and the guide rod is too large.
D. The valve oil seal is leaking oil, and the cylinder is running through the oil.
Excavator blue smoke maintenance:
1. The blue smoke when the excavator is cold is probably caused by the incomplete combustion of oil when the excavator is just started because the ambient temperature is too low.
2. In addition, you can also check whether the oil level of the engine oil pan is excessive. If the oil is excessive, it will cause the blue smoke failure of the excavator.
3. If the oil-water separator is broken, it should be replaced with a new one.
Second, if there is a problem with the turbocharger of the excavator, you need to check the inorganic impellers and the intercooler pipes on both sides of the turbocharger for traces of organic oil. Or replace.
1. If there is a problem with the engine cylinder piston, it needs to be repaired or replaced.
2. If the gap is too large, it needs to be adjusted to eliminate the blue smoke failure of the excavator.
3. The blue smoke phenomenon occurs during the operation of the excavator, which is generally the performance of the failure of the oil burning of the excavator, so you can check the fuel consumption of the excavator, the air filter of the excavator, the turbocharger of the excavator, etc , So as to eliminate the blue smoke caused by excavators.
