Poor Quality Fuel Will Reduce The Service Life Of Diesel Generator Sets

Jul. 19, 2022

Diesel generator sets are the most widely used power generation equipment at present. When purchasing a generator set, I believe that the generator manufacturer must have emphasized to you that when running a diesel generator set, it is necessary to select and add clean diesel oil that meets the requirements according to different sets and the operating environment temperature. In order to save operating costs, some users add cheap "private oil" without permission, which seems to save a lot of oil costs, but it is actually very dangerous.


The use of inferior diesel will make the diesel generator not reach the rated power, the fuel consumption will be higher than the standard of the unit, and the internal parts of the machine will be damaged prematurely. At the same time, the power system of the generator set will not be fully lubricated, the power performance will be reduced, and the time of the unit overhaul period will be shortened. This will lead to an increase in user costs, more manpower and material resources to maintain and care, and will directly affect the service life of the diesel generator set. In addition, poor quality fuel can cause the following hazards:


1. The high sulfur content of diesel oil will destroy the quality of the oil, make the oil prematurely reduce the performance, and make the diesel engine of the diesel generator set not get good lubrication.


2. The high water content will destroy the lubrication of the fuel pump and the precision parts of the fuel injector.


3. It contains a lot of impurities, which damages the fuel pump and the precise parts of the fuel injector, and the wear of the nozzle orifice of the fuel injector becomes larger.


4. The residual carbon content is high, and the combustion produces too much carbon deposition, which affects the combustion effect of the diesel engine. The temperature of the combustion chamber is too high, causing early damage to the ring and cylinder liner.


5. The diesel separator is easily blocked, the power of the generator set decreases, and the replacement interval of the diesel separator is shortened.


6. Inferior diesel oil can easily lead to cylinder pulling, resulting in the overall scrapping of the diesel engine.


7. Inferior diesel oil is not easy to burn, and a lot of exhaust gas will be generated during use.

8. Inferior diesel oil can easily lead to blockage of the third filter of the generator set and affect the service life of the generator set.


9. The low calorific value of diesel fuel cannot reach the specified value. The fuel consumption rate is higher than the rated power of the calibrated diesel engine, which directly leads to a decrease in the power of the diesel generator set.


10. The diesel filter element is easy to be blocked, the power of the diesel generator set is reduced, and the diesel oil replacement interval is shortened.


When choosing fuel, Starlight recommends that users should read more, compare more, and look at product ingredients. Generally, inferior fuel oil is cloudy on the outside, does not reach the specified label and low calorific value, and at the same time contains high sulfur, acrobatics, moisture and residual carbon. The high-quality fuel is clear and low in sulfur (less than 1.0%), low in carbon residue (less than 1.0% by weight), less water and sediment (less than 0.1% by volume), and less ash (less than 0.03%).
