Diesel Generator Fuel Consumption Calculation

Presumably, many people are unclear about how to calculate the fuel consumption of diesel generators. They also wonder why it always seems that the generator consumes fuel very quickly. What exactly is the reason? The editor of Dingbo Power will reveal the answers for you.

To help everyone understand the approximate fuel consumption of diesel generator sets and calculate the operating costs of the generator sets, we have listed the approximate estimated fuel consumption values (from 30kw to 500kw) of the generator sets under full - load conditions for your reference.

30kw fuel consumption = 6.3 kilograms (kg) = 7.8 liters (L)

45kw fuel consumption = 9.45 kilograms (kg) = 11.84 liters (L)

50kw fuel consumption = 10.5 kilograms (kg) = 13.1 liters (L)

75kw fuel consumption = 15.7 kilograms (kg) = 19.7 liters (L)

100kw fuel consumption = 21 kilograms (kg) = 26.25 liters (L)

150kw fuel consumption = 31.5 kilograms (kg) = 39.4 liters (L)

200kw fuel consumption = 40 kilograms (kg) = 50 liters (L)

250kw fuel consumption = 52.5 kilograms (kg) = 65.6 liters (L)

300kw fuel consumption = 63 kilograms (kg) = 78.75 liters (L)

350kw fuel consumption = 73.5 kilograms (kg) = 91.8 liters (L)

400kw fuel consumption = 84.0 kilograms (kg) = 105 liters (L)

450kw fuel consumption = 94.5 kilograms (kg) = 118 liters (L)

500kw fuel consumption = 105 kilograms (kg) = 131.2 liters (L)

The specific calculation method for the fuel consumption of a diesel generator is as follows: One liter of diesel is approximately equal to 0.84 - 0.86 kilograms.

Most manufacturers of diesel generators use the parameter G/KW.H, which means how many grams (G) of fuel a generator set consumes per kilowatt per hour. By converting the unit to liters (L), you can know the hourly fuel - cost. Generally, a diesel generator set consumes 0.21 kg per kilowatt per hour.

After clearly understanding the calculation method of diesel generator fuel consumption, many users are also concerned about the same question: why does their own diesel generator set consume fuel so quickly? The editor has also summarized the following reasons for you.

Five factors affecting excessive fuel consumption of diesel generators:

1.Diesel engine power factor: The greater the power of the diesel engine itself, the higher the fuel consumption.

2.Manufacturer - related factors: Imperfections in the selection of materials for the diesel generator, such as imperfect production technology or the quality of the diesel engine materials, can affect the fuel consumption of the diesel generator set.

3.Assembly issues: Problems in the assembly process of the diesel engine and the generator, such as improper gear matching, can affect the fuel consumption of the generator set.

4.Environmental factors: The working environment of the diesel generator set, including good ventilation and timely heat dissipation, can also affect the fuel consumption of the generator set.

5.Load factor: This is also the most important part. The size of the load carried by the generator set affects the fuel consumption of the diesel generator set.

How to solve the problem of excessive fuel consumption of diesel generators:

First, check whether there is any oil leakage at the connections of the engine body, gear chamber cover, large disc on one side of the traveling wheel, rear cover, cover, etc. If there is oil leakage, pay attention to observing whether the gaskets at each connection are intact, and replace the damaged gaskets. If the gaskets are intact, check whether the connecting screws at each part are loose. Tighten the loose bolts to the specified torque with a wrench. If the above parts are basically normal and the oil leakage is at the frame position, check the oil pan. The main inspection part is at the front end of the oil pan on the same side as the traveling wheel. Usually, due to loose frame screws, the traveling wheel rubs against the angle iron of the frame that protects the oil pan under the pull of the V - belt for a long time, wearing through the oil pan and causing a gap and oil leakage.
