Calculation method of 8-hour fuel consumption of diesel generator set

April 14, 2022
In the use of diesel generator sets, the fuel tank is an indispensable part. Generally speaking, the size of the fuel tank should be able to provide the fuel consumption of the diesel generator set for eight hours under full load. The simplest calculation method is to multiply the power (KW) of the diesel generator set by 2.1 and the figure is approximately equal to the fuel consumption of eight hours. Considering different brands of generator sets, the fuel consumption is slightly different. When calculating the fuel consumption of the generator set, the user can calculate it according to the actual situation.
 
Most of the oil consumption parameters used by the manufacturers of diesel generators use G/KW.H, which means how many grams (G) of oil the generator set consumes per kilowatt per hour, and one liter of diesel is about 0.84-0.86 kg (1L). =0.8-0.85KG), and then change the unit to liters (L) so that you can know the cost of fuel consumption for one hour, and then calculate the fuel consumption for eight hours.
 
The fuel consumption of diesel generators, the following data are for reference only:
 
30kw diesel generator set fuel consumption = 6.3 kilograms (kg) = 7.8 liters (L) 62.4 liters (L) of oil in eight hours
 
45kw diesel generator set fuel consumption = 9.45 kilograms (kg) = 11.84 liters (L) 94.72 liters (L) of fuel in eight hours
 
50kw diesel generator set fuel consumption = 10.5 kilograms (kg) = 13.1 liters (L) 104.8 liters (L) of oil in eight hours
 
75kw diesel generator set fuel consumption = 15.7 kilograms (kg) = 19.7 liters (L) 157.6 liters (L) of oil in eight hours
 
100kw diesel generator set fuel consumption = 21 kilograms (kg) = 26.25 liters (L) 210 liters (L) of oil in eight hours
 
150kw diesel generator set fuel consumption = 31.5 kilograms (kg) = 39.4 liters (L) 315.2 liters (L) of oil in eight hours
 
200kw diesel generator set oil consumption = 40 kilograms (kg) = 50 liters (L) 400 liters (L) of oil in eight hours
 
250kw diesel generator set fuel consumption = 52.5 kilograms (kg) = 65.6 liters (L) 524 liters (L) of oil in eight hours
 
300kw diesel generator set fuel consumption = 63 kilograms (kg) = 78.75 liters (L) 630 liters (L) of oil in eight hours
 
350kw diesel generator set fuel consumption = 73.5 kilograms (kg) = 91.8 liters (L) 734.4 liters (L) of oil in eight hours
 
400kw diesel generator set fuel consumption = 84.00 kilograms (kg) = 105.00 liters (L) 840 liters (L) of oil in eight hours
 
450kw diesel generator set fuel consumption = 94.50 kilograms (kg) = 118.00 liters (L) 944 liters (L) of oil in eight hours
 
500kw diesel generator set oil consumption = 105.00 kilograms (kg) = 131.20 (L) 1048 liters (L) of oil in eight hours
