Correction оf Properties оf Modern Diesel Fuels Using Additives

Creation of high quality diesel fuels for internal combustion engines that meet stringent operational and environmental requirements is currently an urgent task. The most rational way to improve the performance characteristics of diesel fuel, its environmental properties, as well as to reduce losses during its storage, is to use polyfunctional additives. Requirements for the structure of polyfunctional additives are formulated. It is shown that their stabilizing and protective effects are the higher, the greater the value of the dipole moment and total electron density on heteroatoms. Amides and esters of higher aliphatic acids, synthesized from renewable diesel raw materials, as well as molecules of azo compounds including aromatic fragments and electron-donating functional groups, are promising multifunctional additives to diesel fuel.
