Five Techniques for Fuel Consumption Calculation and Fuel Saving of Different Types of Generator Sets

Source: Tianjin Generator Leasing Company | Release time: 2018-12-20
How do we calculate the fuel consumption when buying a diesel generator? There are two main factors in the fuel consumption of a generator. Before the customer purchases the generator set, in order to understand the cost of its fuel consumption, most diesel generator set customers do not know the amount of fuel consumption of the diesel generator set and how to calculate the fuel consumption of the diesel generator set, they will first consult the generator set The amount of fuel consumed; in fact it is difficult to have a unified statement. Generally speaking, the fuel consumption of a diesel generator is related to the following two factors:
1. Fuel consumption rate: Different brands of diesel generator sets have different fuel consumption rates and different fuel consumption;
Second, the size of the electric load, the larger the load is, the larger the fuel consumption is, the larger the load is, and the smaller the relative fuel consumption is, the smaller it is.
In order to facilitate everyone to understand the approximate fuel consumption of the generator set, calculate the use cost of the generator set; Yinjiang Power Generation will calculate the approximate reference value (30kw-500kw) for everyone.

Model (kw)

Weight (kg)

Fuel consumption (L)

Model (kw)

Weight (kg)

Fuel consumption (L)

30kw 6.3 kg (kg)

7.8 liters (L)

200kw 40 kg (kg) 50 liters (L)
45kw 9.45 kg (kg) 11.84 liters (L) 250kw 52.5 kg (kg) 65.6 liters (L)
50kw 10.5 kg (kg) 13.1 liters (L) 300kw 63 kg (kg) 78.75 liters (L)
75kw 15.7 kg (kg) 19.7 liters (L) 350kw 73.5 kg (kg) 91.8 liters (L)
100kw 21 kg (kg) 26.25 liters (L) 400kw 84.00 kilograms (kg) 105.00 liters (L)
150kw 31.5 kg (kg) 39.4 liters (L) 450kw 94.50 kilograms (kg) 118.00 liters (L)

Fuel consumption of 500kw diesel generator set = 105.00 kilograms (kg) = 131.20 liters (L) The above are only estimates and are for reference only.


The specific calculation method for the fuel consumption of diesel generators is as follows:
One liter of diesel is about 0.84-0.86 kg (1L = 0.8-0.85KG).
Most manufacturers of diesel generators use the parameters G / KW.H, which means how many grams (G) of oil is consumed per kilowatt per hour of the generator set, and then the unit is changed to liters (L) to know that you Fuel cost per hour.
Five tips to save fuel for different generator types

Looking for power for generator rental, welcome to inquire!
First, diesel purification. Diesel contains a variety of minerals and impurities. If it is not precipitated, filtered and purified, it will affect the work of the plunger and the injector, resulting in uneven fuel supply and poor atomization of the fuel, which will reduce the engine power and increase fuel consumption. Therefore, it is recommended to let the diesel oil stand for a period of time to allow impurities to settle, and filter the funnel with a filter when refueling. Then it is to clean or replace the filter regularly to achieve the purpose of purification.
Second, remove coke. During the work of a diesel engine, polymers are attached to the valves, valve seats, injectors and the top of the piston. These carbon deposits will increase fuel consumption and should be removed in a timely manner.
Third, maintain water temperature . The cooling water temperature of the diesel engine is too low, which will cause incomplete combustion of the diesel, affect the performance of the power, and waste fuel. Therefore, it is necessary to properly use insulation curtains. Note that soft water that does not contain minerals, such as flowing river water, is preferred.
Fourth, do not overload. When the machinery is overloaded, it emits black smoke, which is an insufficiently burned fuel emission. As long as the machine emits black smoke, it will increase fuel consumption and shorten the service life of components.
5. Regular inspections and timely repairs. To achieve eye-care and hand-care, inspect the machinery regularly or irregularly, maintain and repair, and firmly establish the concept of "emphasis on healing, prevention on repair", and do not let machinery work with illness.
