Reduction of carbon footprint is a world community key goal. Modern corporations for motor-cars and their components manufacture are working hard on carbon footprint reduction by developing more effective and powerful combustion engines running on diesel fuel. Growth of requirements concerns both combustion engines and quality of fuel for these engines. Minute particles of mechanical impurities available in the diesel fuel in suspension could result in seizure of moving members of high-pressure pumps and combustion engines; in this connection qualitative purification of diesel fuel is required in case of its contamination. Filtration is the main method of diesel fuel purification against mechanical impurities. Filtering elements with filtration degree of 1 µm are required to remove minute particles of mechanical impurities. In case of strong contamination and high diesel fuel amounts, filtering elements are quickly clogged that causes their frequent replacement and operational costs increase. In this connection, searching for alternate diesel fuel purification methods is topical issue.

The article presents results of laboratory and field tests of various diesel fuel purification methods, which permit to evaluate their effectiveness in removing minute suspended particles from the diesel fuel. The authors have found that effectiveness of filtration with using various filtering elements, including gauze, cellulose and polymeric ones, diminishes with time. In addition, the performed studies demonstrate that there is a number of alternate methods for diesel fuel purification. Purification effectiveness of these methods is comparable with that of filtration, and their effectiveness is not decrease with time. It could be concluded from the obtained data that several techniques shall be considered when selecting a purification method, including their possible combinations.
