The blue smoke emitted by excavators is also known as "excavator burning oil". The main reason is that the abnormal burning of excavator burning oil will increase the carbon deposit in the engine cylinder, reduce the engine power, and hold the car. In serious cases, the engine may also be scrapped. What are the reasons for the blue smoke from the excavator?
1. Blue smoke is emitted when the engine is started in cold state.
If blue smoke occurs when starting the engine in cold state, it is determined that the engine oil is burned in cold state. This situation is generally due to the aging of the valve oil seal, resulting in a decline in sealing effect, making the engine oil enter the cylinder through the valve oil seal and burn, producing blue smoke.
2. The engine emits blue smoke when accelerating.
If the engine accelerator emits a lot of blue smoke when the load suddenly increases during operation, it is preliminarily judged that the sealing clearance between the piston and the cylinder barrel in the engine cylinder is too large. This phenomenon is due to the large gap between the cylinder and the piston or piston ring and the large amount of blue smoke generated by the oil passing through the oil pan when the engine is working at a high throttle.
3. The engine emits a lot of blue smoke at any time.
The engine emits a lot of blue smoke at any time, which proves that the engine has been seriously worn and must be overhauled. If it is not repaired in time, it is very likely to cause engine cylinder pulling, or even engine scrapping, resulting in more serious losses.
To sum up, the blue smoke from the engine is the phenomenon that the engine oil runs into the cylinder. In the daily use of machinery, the aircraft users should observe the use of the equipment and eliminate the hidden dangers caused by the blue smoke from the equipment as soon as possible.
