This can be caused by various things:

  • when there is water in diesel fuel;
  • when the diesel generating set has been working for approximately 1 hour with a very small load;
  • when the fuel filter is replaced too late and there is dirt in the diesel fuel;
  • when maintenance is carried out too late or poorly.

The engine starts smoking and stumbling because the injectors are carbonized. You can prevent this by making your generating set run under heavier loads.
A 70-80% load is optimal for the consumption and the lifespan of a diesel generating set.
