The precautions for fuel used in
diesel engines mainly include the following aspects:
1. Choose the appropriate fuel:
Fuel type: Diesel can be classified into different grades such as 0, 10, -20, etc. according to its freezing point. Diesel with a lower freezing point is suitable for low-temperature environments, while diesel with a higher freezing point is suitable for high-temperature environments. When choosing fuel, it should be determined based on the power demand of the diesel generator set and the ambient temperature.
Fuel quality: High quality diesel has high combustion efficiency and can reduce engine wear and failure. You should choose fuel from legitimate channels and avoid using inferior fuel.
2. Use and maintenance of fuel:
Shutdown cooling: Before replacing the fuel, the machine should be shut down and wait for it to cool down to a certain temperature to avoid fuel splashing or causing a fire due to high temperatures.
Cleaning the fuel tank: Before replacing the fuel, the fuel tank should be thoroughly cleaned to remove impurities and sediment, ensuring the cleanliness of the new fuel.
Replacing the filter: The fuel filter is an important component to prevent impurities from entering the engine. When replacing the fuel, the filter should be replaced at the same time.
Check the oil quality and level: After adding new fuel, the fuel level and quality should be checked to ensure that the refueling amount is appropriate and the quality is qualified. At the same time, check whether there are leaks in the fuel pipeline and connections.
3. Safety measures:
Fire and explosion prevention: When adding fuel, attention should be paid to the surrounding environment, smoking is strictly prohibited, and fire and explosion prevention measures should be taken.
Environmental temperature: Choose the appropriate diesel fuel based on the environmental temperature of the usage area. For example, 10 # light diesel fuel can be used in southern regions, while -20 # and -35 # light diesel fuel can be used in cold and high-altitude northern regions during winter.
By following the above precautions, the normal operation of the diesel engine can be effectively ensured and its service life can be extended.
