What does a fuel oil purifier do?

A fuel oil purifier plays a crucial role in maintaining the quality of fuel used in marine engines. Its primary function is to remove impurities and water from the fuel oil before it is fed into the engine. This process is essential because contaminants like dirt, sludge, and water can compromise engine performance, lead to increased wear, and ultimately result in engine failure or inefficiency.

The purification process often involves the use of centrifugal force to separate the heavier impurities and water from the lighter fuel oil. By effectively cleaning the fuel, the purifier ensures that only the highest quality oil enters the engine, which enhances combustion efficiency, reduces emissions, and improves overall operational reliability.

In contrast to other options, increasing oil pressure, combining different fuel grades, or heating oil may be part of broader fuel management systems, but they do not capture the specific and critical function of a fuel oil purifier, which is to clean the fuel by removing unwanted elements.
