What's wrong with the lack of oil and blue smoke after the engine of Xugong excavator Isuzu 6hk1 heats up? _Baidu...

Blue smoke from the excavator engine is generally caused by incomplete combustion, and there are many possible reasons. First of all, there may be problems with the quality of fuel, such as the oil is too thin or mixed with impurities. Secondly, the mixing ratio of air and fuel in the combustion chamber is incorrect, resulting in insufficient combustion.

The cylinder liner piston wears out and the engine output power decreases, resulting in a large exhaust gas from the excavator engine. The engine piston ring and cylinder liner filter wear and tear.The viscosity grade used in engine oil is low, or the oil deteriorates due to long-term non-replacement, resulting in a decrease in viscosity.

This situation is generally caused by the aging of the valve oil seal, resulting in a decline in the sealing effect, causing the oil to enter the cylinder through the valve oil seal and burn, producing blue smoke, that is, the "lower leakage" mentioned above.
