The primary purpose of a fuel oil purifying system is to remove impurities from fuel oil before it is used in the engine. This process is crucial because any contaminants such as water, sediments, or particulates in the fuel can lead to inefficient combustion, engine wear, and potential damage. By purifying the fuel oil, the system ensures that only clean fuel enters the engine, which promotes optimal performance, efficiency, and longevity of the equipment.

Fuel oil purifiers typically use centrifugal force or other methods to separate impurities based on density differences. This results in cleaner fuel that reduces the risk of problems such as clogging filters or injectors, as well as reducing emissions due to incomplete combustion. Thus, the operation of a purifying system is a key aspect of maintaining fuel quality and ensuring reliable engine operation.
