The excavator emits white smoke when the water temperature is high. If the injection time is not running, it seems that the engine oil is burned. The engine oil pressure is too high, the oil seal of the supercharger leaks oil, and the valve guide is worn It may be that the matching gap between the piston ring and the steel barrel is too large and the engine oil will be burned. Try a repair agent such as carbon deposit.
If it is just overhauled, it can be automatically eliminated after running in for a period of time. Or the oil supply time is late after the pump is calibrated. It may also be that the machine is aging and needs overhauling.
It's normal to start now, and blue smoke will appear when the car is cold The main problem now is to see how little the oil is. Under normal working conditions, the oil is much less. It may be necessary to repair the engine.
The blue smoke of the engine is mainly caused by oil burning. The engine operates at low speed and low temperature for a long time, the cylinder liner piston is worn, the cylinder wall clearance is large, the piston ring is stuck or inflexible, the oil pressure is too high, the valve guide is seriously worn, and the oil seal of the supercharger leaks oil, etc. can cause oil burning If it's just started, the low-speed car emits blue smoke, and the hot car does not emit blue smoke at high speed, there's no problem. If the hot car emits heavy smoke, it needs to be repaired.
In addition, the water tank is connected with the auxiliary water tank If the water in the water tank is insufficient, the water in the auxiliary water tank will be sucked first. When the water temperature in the water tank is high (heat rises and cold shrinks), the water will also go to the auxiliary water tank The auxiliary water tank is only three or four liters of water. Fill the auxiliary water tank with water. Check the water pipe connected to the auxiliary water tank to see if the auxiliary water tank is displaced.
It may be that the cylinder pad is flushed, and the working room of the engine is connected to the water channel through the cylinder pad. When the engine is cooled, open the main water tank cover, and then hit the machine to see if there are bubbles in the water inside? Yes, it's necessary to replace the cylinder gasket. No, try to add a little throttle and see if there is one.
