Why is the Da Fenghuang Refrigerator Emitting Black Smoke?
2 Answers
The reason why the Da Fenghuang refrigerator emits black smoke is that the exhaust gas contains excessive carbon particles, caused by incomplete combustion during engine operation. Below are the measures to address black smoke emission: Small amount of black smoke from the exhaust pipe: If the engine exhaust pipe emits a small amount of black smoke accompanied by rhythmic "popping" sounds, it can be determined that a few cylinders are not working or the ignition timing is incorrect. The non-working cylinder can be identified using the cylinder cut-off method, or the ignition timing can be checked and adjusted. Large amount of black smoke from the exhaust pipe: If the engine exhaust pipe emits a large amount of black smoke accompanied by backfiring sounds, it can be determined that the air-fuel mixture is too rich. The choke valve should be checked immediately to ensure it is fully open, and high-speed maintenance should be performed if necessary. After turning off the engine, check the main nozzle from the carburetor port; if there is fuel injection or dripping, the fuel level in the float chamber is too high and should be adjusted to the specified range, and the main jet should be tightened or replaced. If the air filter is clogged, it should be cleaned or replaced.
I remember last time seeing my friend's Da Fenghuang refrigerator emitting black smoke, which is mostly a sign of mechanical component failure, like the motor in the compressor burning out, causing internal parts to combust and smoke. Possible causes include insufficient lubrication, refrigerant leakage, or the belt being too tight and slipping. Once the compressor overheats, it can produce a large amount of black smoke, which is definitely dangerous. If you encounter this issue, I recommend immediately shutting down and cutting off the power to avoid fire hazards. Then, check the compressor's operating sound—if there's abnormal noise or a strong smell of smoke, don't attempt to fix it yourself—call a professional technician right away. For prevention, regularly cleaning the radiator and adding lubricant can reduce this risk, especially during high-load summer use when you should be extra careful not to overwork the machine. Abnormal operation of the refrigeration system can also lead to other issues, such as battery short circuits, so don't overlook routine maintenance details. In short, safety comes first—don't delay repairs.
