Key Considerations for Diesel Generators' Safe and Efficient Use

Oct 09, 2023


Diesel generator sets should be used with careful attention to the following aspects:


  1. Pay Attention to Usage Environment

  2. 1. Generators should be placed outdoors or in well-ventilated machine rooms, away from doors, windows, and vents to prevent carbon monoxide from entering indoor spaces.

  3. 2. Avoid using generators near flammable and explosive materials.

  4. 3. Generators should be placed in dry areas. If outdoor installation is necessary, use a canopy-style structure to protect against contact accidents due to moisture.


  5. Handle Fuel Storage and Usage with Care

  6. 1. Diesel fuel for generators should be stored in dedicated storage facilities that meet fire department regulations.

  7. 2. The type of fuel used should match the requirements specified in the generator's user manual or label.

  8. 3. Before adding fuel, shut down the generator and allow it to cool to prevent the risk of fire caused by fuel coming into contact with hot engine components.

  9. Ensure Proper Wiring Connections for the Generator

  10. 1. Outdoor electrical cables must meet the requirements of the electrical load.

  11. 2. When using extended power cables, ensure good insulation between the cable and the ground.

  12. 3. Do not directly plug the generator's output into residential power outlets, as this can cause feedback and potentially result in electric shock accidents for users powered by the same transformer. The correct connection method is to have an electrician install a power transfer switch.


  13. Keep Diesel Clean

  14. Before adding diesel to the tank, it should be allowed to settle for at least three days. During refueling, thorough filtration is necessary to prevent mechanical impurities from contaminating the fuel. Maintain the cleanliness of fuel storage containers and refueling equipment during operations.


  15. Do Not Mix Diesel with Other Fuels

  16. Mixing other fuels with diesel significantly impairs its combustion performance, leading to starting difficulties or even failure to start. The presence of other fuels in the cylinder can also wash away the cylinder's lubricating oil film, accelerating cylinder wear.


  17. Choose High-Quality Diesel Whenever Possible

  18. The quality of diesel directly affects the proper operation of diesel engines. Using low-quality diesel can reduce engine power due to poor combustion, leading to inadequate performance. Prolonged use of low-quality diesel can accelerate wear and reduce the diesel engine's lifespan. Therefore, it is advisable to select high-quality diesel with an appropriate rating.


This comprehensive guide emphasizes safety and efficiency in the use of diesel generators, highlighting critical considerations for their proper operation.
