1.Diesel oil quality is poor
The performance index of diesel fuel used does not meet the standard requirements, resulting in poor fuel combustion and black smoke. Secondly, the quality of diesel is not good, will damage the diesel filter, resulting in diesel deterioration inside the diesel engine, resulting in the phenomenon of black smoke.
2. Air inlet is blocked
The fuel tank of the diesel generator is not sealed. Due to long-term contact with the air, it is inevitable that impurities and dust in the air will fall into the air filter. These particles can clog the air intake and provide insufficient air during diesel combustion, which can easily lead to incomplete combustion and black smoke from diesel generators.
3. Insufficient compression force
One of the conditions of diesel combustion is the combustion environment with a certain pressure. But if the valve, piston ring and other wear, it will make the compression pressure is insufficient, leading to the pressure needed to meet the requirements of combustion, so that the combustion conditions become worse, there will be black smoke from the diesel generator.
4. Change of combustion environment
Long-term use of diesel generators and other factors can lead to changes in the shape and volume of the combustion chamber, which can further lead to a decrease in the quality of fuel and air mixture, not forming a good mixture, and poor combustion conditions can produce black smoke.
5. The oil supply is too large
If in the normal operation of the diesel generator, the diesel poured into the diesel engine is far more than the diesel required to work, this behavior will make the mixture is too thick, so it is easy to cause incomplete diesel combustion, resulting in black smoke.
