The larger the load of the diesel generator set, the higher the fuel consumption

The fuel consumption of diesel generator sets is related to two main factors: the fuel consumption rate of the unit itself and the load size. In general, diesel generator sets of the same brand and model will increase their fuel consumption as the load increases. This is because the increase in load requires the generator set to provide more energy, leading to an increase in fuel consumption. This relationship reaches a balance point at 80% load, where fuel consumption is relatively low. If the load is below 20%, it may cause damage to the generator set, not only significantly increasing fuel consumption, but also potentially damaging the unit. Therefore, in order to maintain the efficiency of the generator set and extend its service life, it is recommended to operate the generator set at around 80% of the rated load.

In addition, phenomena such as oil dripping and leakage in diesel generator sets can also lead to increased fuel consumption. Therefore, regular inspections and maintenance of the generator set should be carried out during use to ensure its normal operation and avoid unnecessary fuel consumption increases.
