Results are presented for a study on the development of methods to remove gum, sulfur, and other impurities from diesel fuels at the site of use. The removal of dissolved impurities in diesel fuel is possible by a physicochemical method, having first enlarged these impurities using coagulants. The introduction of carbamide dissolved in water into the fuel permits a reduction in the content of gum and sulfur and an increase in the anti-wear properties of diesel fuel. The use of monoethanolamine in a mixture with isopropyl alcohol in the following step of fuel treatment increases the efficiency of the impurity removal process and further reduces the fuel sulfur and gum impurity indices.
