Excavation machine black smoke appears to be a small problem, but if it is not handled in time, it may cause the excavator to burn engine oil, and even cause damage to the engine ’s four sets and eventually cause overhaul.
Failure classification:
1 The black smoke is emitted from the lower exhaust gas just after starting.
2 The black smoke has been discharged during the excavator operation. (At this time, it may be accompanied by an increase in the oil consumption of the excavator and the phenomenon of burning the oil.)
Reasons for black smoke of excavate engine:
1.If there is black smoke when the excavator is just started, and it gradually disappears after a period of time after startup, it is normal.If you have any doubt, you can inspect the three filters (Oil filter, Diesel filter, Air Cleaner. In fact, there are no more than three filter elements on the excavate machine, two diesel filter elements, one coarse filter, one fine filter, one oil filter element, two space filter elements, one internal Filter, one external filter, two hydraulic oil filter elements, one oil inlet and one oil return, and some excavators also have pilot filter elements)
2.The black smoke phenomenon has been emitted during the excavator operation, and accompanied by the increase in fuel consumption, the causes of the failure are:
①The air cleaner of the excavator is blocked, the engine has less air intake, the fuel enters the combustion chamber and is not completely burned, and the smoke is discharged. Repairing the excavator The commissioning department composed of professional technicians professionally inspects and debugs the hydraulic system of various models of excavators, and has an excellent computer testing test bench to make your machine fully use its benefits. To provide our customers with professional 24-hour warranty service, a phone call, one step in place, to provide you with fast and excellent service. Constantly exploring innovation and providing customers with higher quality technical services, all accessible people look forward to your visit!
② The valve clearance of the excavator engine is too small, the air intake is insufficient, and the air intake system is faulty.
③ Diesel pump (Deep well pump) oil supply is too large, poor atomization of the fuel injection nozzle, oil dripping from the oil nozzle.
④ The pressure of the excavator cylinder (compressed air) is insufficient and the combustion is not good.

At the same time, our company has a relatively advanced domestic imported engineering machinery hydraulic system test bench, which can accurately judge and repair and adjust the difficult hydraulic system of imported engineering machinery in different countries to restore the effect of the mechanical equipment.
⑤ The oil inlet of the supercharger leaks oil, and the oil enters the supercharger. At high temperature, the exhaust gas makes the oil black, and the excavate engine emits black smoke.
⑥ If the black smoke is accompanied by the phenomenon of excavator dredging, it is caused by the failure of the hydraulic systems of the excavator (too much pressure).
中 With a medium-cooled engine, the fins are blocked by dust due to long-term operation and cannot absorb air, causing black smoke.
⑧ If the black smoke only lasts for a while, it may be caused by the driver operating the throttle too much.
⑨Too much engine load or pressure and too much carbon (C) in the cylinder may cause the smoke of the excavator engine to emit black smoke.
⑩The timing is incorrect, and the fuel supply time is incorrect.
