How to calculate the fuel consumption rate of diesel generator sets?

Multiple users should ask the fuel consumption of diesel generator sets before purchasing a diesel generator, which is used to calculate the cost of diesel generator sets because the brands of the generator sets are much larger, and the power segments are more, the generator fuel consumption of different power segments Different, the fuel consumption of different brands is also different, so it is two factors, brands and powers of fuel consumption.
Below our company's technical personnel calculate the fuel consumption of the 30kW-diesel generator set supplied by our company.

30KW diesel generator set fuel consumption = 6.3 kg (kg) = 7.8 liters (L)

45KW diesel generator set fuel consumption = 9.45 kg (kg) = 11.84 liters (L)

50KW diesel generator set fuel consumption = 10.5 kg (kg) = 13.1 liter (L)

75KW diesel generator set fuel consumption = 15.7 kg (kg) = 19.7 liters (L)

100KW diesel generator set fuel consumption = 21 kg (kg) = 26.25 liters (L)

150KW diesel generator set fuel consumption = 31.5 kg (kg) = 39.4 liters (L)

200kw diesel generator set fuel consumption = 40 kg (kg) = 50 liters (L)

250KW diesel generator set fuel consumption = 52.5 kg (kg) = 65.6 liters (L)

300KW diesel generator set fuel consumption = 63 kg (kg) = 78.75 liters (L)

350KW diesel generator set fuel consumption = 73.5 kg (kg) = 91.8 liters (L)

400KW diesel generator set fuel consumption = 84.00 kg (kg) = 105.00 liters (L)

450KW diesel generator set fuel consumption = 94.50 kg (kg) = 118.00 liters (L)

500KW diesel generator set fuel consumption = 105.00 kg (kg) = 131.20 liters (L)
