During the summer construction, the excavator is hovering at the edge of high intensity. At this time, the excavator master is most afraid of encountering abnormal phenomena in the excavator rental work. Especially the black smoke fault, because once the fault occurs, it basically indicates the shutdown for repair. The failure of the excavator to emit black smoke is a headache for the airplane friends.
When the power of the first engine is insufficient, when the fuel injection to the cylinder is increased, the engine does not burn fully, so it emits black smoke. This problem is a normal phenomenon. For example, when you dig a rock, the engine will emit a black smoke.
Second, the maintenance of the engine is not enough. Because there are more diesel impurities added to the excavator, the service life of the fuel filter element becomes shorter, which will also cause black smoke from the engine, insufficient power, and stuffiness.
Third, the engine fuel injector is broken and cannot be atomized and injected into the cylinder, causing black smoke. In this case, as long as the cylinder is disconnected for testing and the fuel injector is replaced after it is found, the problem can also be solved quickly
The problem of black smoke from the engine is one of the most difficult faults to deal with. Many bosses also want to eradicate the fault once and for all, but the idea is good and it is very difficult to achieve. Because there are many reasons for the failure, such as the situation introduced to you today. Before troubleshooting, you must determine the cause of the failure through inspection and measurement. If necessary, you must find a professional maintenance technician to solve the problem accurately and quickly!
