Many customers emit black smoke after buying diesel generators and using them for a period of time, but many people do not know the reasons for this phenomenon. Today, Raines will explain in detail the main factors of black smoke from diesel engines.
Solutions to black smoke from diesel generator set:
1. Damaged air filter
This is a common reason. Due to the different working environment of diesel generator sets, there is a large accumulation of dust or particles in the air. Therefore, it is necessary to clean it regularly. It is recommended to clean it every 5000 km in heavily polluted areas, and every 8000-10000 km in areas with good air quality. In order to avoid air intake obstruction and black smoke caused by insufficient combustion. The conventional treatment method is cleaning. If the effect is poor, it is recommended to replace it.
2. The oil circuit is blocked
The maintenance personnel pointed out that the oil circuit will also cause black smoke because carbon deposition will lead to difficult oil supply. If the local diesel brand is not ideal, diesel additives can be added appropriately to support combustion and clean the oil circuit. If the condition is not good, it is recommended to let professional maintenance personnel check it to avoid working with the equipment for a long time and causing greater losses to the damaged equipment.
3. Poor operation of equipment
Common problems are: overload operation of diesel generator set, abnormal fuel injection of fuel injection pump, bearing bush of generator, etc. will lead to black smoke. Please pay attention to check the equipment.
4. The fuel filter is damaged
In many areas, due to different specifications and quality of diesel, some particles are not filtered into the engine, resulting in insufficient combustion and black smoke. First, check whether the fuel filter is effective, and replace it in time in case of damage or failure.
5. Intake air temperature is too high
Pay attention to the temperature of the operating environment. High temperature will reduce the oxygen content and cause insufficient combustion of oxygen. It is recommended to make the ambient temperature of the equipment moderate and install cooling devices to avoid this situation.
